Regardless of shape, all fused quartz components are amorphous, isotropic, and free of the grain boundaries that would otherwise create sites for thermally and chemically preferential attack.<\/p>\n<hr \/>\n<p><img decoding=\"async\" src=\"https:\/\/toquartz.com\/wp-content\/uploads\/2026\/02\/Quartz-Glassware-Components-in-Semiconductor-Cleanroom-Fabrication.webp\" alt=\"Quartz Glassware Components in Semiconductor Cleanroom Fabrication\" title=\"Quartz Glassware Components in Semiconductor Cleanroom Fabrication\" \/><\/p>\n<h2>Applications of Quartz Glassware in Semiconductor Fabrication<\/h2>\n<p>Semiconductor manufacturing subjects materials to a combination of extreme temperature, ultra-high purity requirements, and aggressive chemical exposure that eliminates virtually every glass alternative \u2014 placing fused quartz at the structural and chemical center of modern wafer processing infrastructure.<\/p>\n<p>Within a silicon wafer fabrication facility, quartz glassware and quartz-based components appear at nearly every thermal and wet chemical processing stage. The purity requirements in this context are not laboratory-grade but semiconductor-grade: <strong>metallic contamination at even single-digit parts-per-trillion concentrations<\/strong> on wafer surfaces can alter carrier lifetimes, introduce gate oxide defects, and reduce device yields. Every quartz component in contact with wafers or process gases must therefore meet stringent specifications that go beyond standard industrial fused quartz into semiconductor-grade and electronic-grade classifications.<\/p>\n<h3>Diffusion Furnace Tubes and Boat Assemblies in Wafer Processing<\/h3>\n<p>Diffusion furnace tubes represent the highest-volume and most thermally demanding application of quartz glassware in semiconductor manufacturing. These large-diameter tubes \u2014 typically 150 mm to 300 mm outer diameter, with lengths up to 1,500 mm \u2014 house silicon wafers during thermal oxidation, dopant diffusion, and anneal processes conducted between 800 \u00b0C and 1,200 \u00b0C in controlled atmospheres of oxygen, nitrogen, or hydrogen.<\/p>\n<p><strong>The quartz used for semiconductor diffusion tubes must meet electronic-grade purity specifications<\/strong>, with total metallic impurity content below 20 parts per billion and, in leading-edge fabs, below 5 ppb for critical elements including iron, copper, nickel, and aluminum. A single iron atom diffusing from a contaminated furnace tube wall into a silicon wafer at 1,000 \u00b0C creates a deep-level trap state that measurably degrades minority carrier lifetime \u2014 a defect directly traceable to material quality. Wafer boats (carriers that hold wafers in vertical or horizontal arrays within the tube) are similarly manufactured from high-purity fused quartz, with slot geometries machined to micron-level tolerances to ensure uniform wafer spacing and reproducible gas flow distribution.<\/p>\n<p>Furnace tube lifetimes in production fabs are carefully tracked, as prolonged thermal cycling gradually induces devitrification \u2014 a surface crystallization phenomenon observable as a milky opacity \u2014 that increases particulate shedding risk and prompts scheduled tube replacement.<\/p>\n<h3>Wet Bench Etching Trays and Chemical-Resistant Process Vessels<\/h3>\n<p>Wet chemical processing stations \u2014 known in semiconductor manufacturing as wet benches \u2014 use immersion tanks, overflow weirs, and transfer trays fabricated from fused quartz to expose wafers to sequential chemical baths.

The mechanical rigidity of quartz at operating temperature also maintains dimensional precision in wafer carrier slot geometry, preventing wafer-to-wafer contact during chemical immersion \u2014 a contact event that would introduce cross-contamination and yield loss.<\/p>\n<p>Cleanroom-grade quartz wet bench components are produced with surface finishes specified in Ra values, typically below 0.8 \u03bcm, to minimize particle adhesion and facilitate complete chemical rinsing between process steps.<\/p>\n<h3>Quartz Components in CVD and Epitaxial Growth Chambers<\/h3>\n<p>Chemical vapor deposition and epitaxial growth processes demand quartz components that simultaneously withstand high temperatures, corrosive deposition precursor gases, and the requirement for zero metallic contamination of the growing film. Quartz reaction tubes, liner tubes, and susceptor components appear across low-pressure CVD (LPCVD), atmospheric-pressure CVD (APCVD), and silicon epitaxial reactors operating between 600 \u00b0C and 1,200 \u00b0C.<\/p>\n<p>In LPCVD systems depositing silicon nitride from dichlorosilane (SiH\u2082Cl\u2082) and ammonia (NH\u2083), or depositing polysilicon from silane (SiH\u2084), the quartz tube serves as the primary reaction envelope. <strong>The tube must remain chemically inert to deposition precursors, carrier gases, and etch-back chemistries<\/strong> including chlorine and HCl used for in-situ cleaning between deposition cycles. Any reaction between the tube wall and process chemistry would introduce silicon oxide or contamination species into the growing film. In epitaxial growth chambers, quartz liner tubes and bell jars provide a clean, thermally transparent enclosure around the susceptor and substrate, allowing infrared heating lamps \u2014 typically tungsten-halogen \u2014 to transmit energy through the quartz walls with minimal absorption loss.<\/p>\n<h4>Quartz Glassware in Semiconductor Process Applications<\/h4>\n<table>\n<thead>\n<tr>\n<th>S\u00fcre\u00e7<\/th>\n<th>Quartz Component<\/th>\n<th>Operating Temp.

A vessel that absorbs UV radiation at the measurement wavelength introduces systematic error in every absorbance reading; a digestion flask that leaches silicon, boron, or sodium into an acid matrix raises the analytical blank and degrades detection limits. Fused quartz addresses both failure modes simultaneously, which explains its mandatory status in UV spectrophotometry and trace element sample preparation \u2014 fields where analytical credibility depends on the behavior of every material in contact with the sample.<\/p>\n<h3>UV-Vis Spectrophotometry Cuvettes \u2014 Why Optical-Grade Quartz Is Non-Negotiable<\/h3>\n<p>UV-Vis spectrophotometry quantifies the concentration of absorbing species by measuring the attenuation of light passing through a sample solution across wavelengths typically spanning 190 nm to 900 nm. The cuvette \u2014 the sample cell through which the beam passes \u2014 must be transparent across this entire range; any absorption by the cuvette material itself introduces a baseline error that propagates directly into every concentration calculation.<\/p>\n<p>Standard optical glass cuvettes transmit adequately above approximately 340 nm, covering the visible range and long-wavelength near-UV. <strong>Below 310 nm, borosilicate glass absorbs so strongly that it becomes functionally opaque<\/strong>, making glass cuvettes incompatible with measurements of aromatic compounds, nucleic acids (peak absorbance at 260 nm), proteins (peak absorbance at 280 nm), and a large class of inorganic ions with UV charge-transfer absorptions. Fused quartz cuvettes maintain greater than <strong>80% transmission at 200 nm<\/strong> in high-purity synthetic grades, enabling reliable measurement throughout the deep UV range.<\/p>\n<p>Standard analytical quartz cuvettes are manufactured with a path length of <strong>10.000 \u00b1 0.010 mm<\/strong>, a tolerance maintained through precision grinding and polishing of the optical windows. Deviations from this path length directly translate into proportional errors in Beer-Lambert law calculations. <strong>Optical-grade synthetic fused silica cuvettes additionally specify refractive index homogeneity across the window aperture<\/strong>, ensuring that beam steering artifacts do not contribute to apparent absorbance \u2014 a specification irrelevant for glass cuvettes but critical for cuvettes used with high-brightness UV sources or in quantitative structural biology applications.<\/p>\n<h3>Digestion Vessels and Acid Dissolution Flasks for Trace Element Analysis<\/h3>\n<p>Trace element analysis by ICP-MS and ICP-OES requires sample dissolution in mineral acids \u2014 typically concentrated HNO\u2083, HCl, or HNO\u2083\/HCl mixtures \u2014 at temperatures between 80 \u00b0C and 250 \u00b0C, for durations ranging from minutes to several hours. The vessel used for this digestion step is the most contamination-critical item in the entire analytical workflow.<\/p>\n<p><strong>Borosilicate glass digestion vessels release boron at concentrations of 50\u2013500 \u03bcg\/L<\/strong> into hot nitric acid solutions, a contamination level that is analytically significant in environmental and biological samples where boron is itself an analyte. Sodium and aluminum leaching from glass vessels adds further matrix complexity and raises the analytical blank for these elements. Fused quartz vessels contribute silicon to solution (as silicic acid) at measurable concentrations in hot HF-free acid media, but silicon is not an analyte in most ICP workflows and is easily accounted for. <strong>For all other elements, the quartz matrix blank contribution is negligible at the sub-\u03bcg\/L level<\/strong>, enabling detection limits that are unachievable with glass or even high-grade PTFE vessels for elements where PTFE additives introduce contamination.<\/p>\n<p>In geochemical analysis of rock and mineral samples \u2014 a field where accurate determination of rare earth elements, transition metals, and platinum group elements at ng\/g concentrations is standard \u2014 quartz digestion vessels are considered the minimum acceptable vessel material for open-vessel acid dissolution at atmospheric pressure.<\/p>\n<h4>Quartz Glassware Performance in Analytical Measurement Applications<\/h4>\n<table>\n<thead>\n<tr>\n<th>Uygulama<\/th>\n<th>Temel Gereksinim<\/th>\n<th>Quartz Specification<\/th>\n<th>Alternative Material Limitation<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>UV-Vis at 200\u2013280 nm<\/td>\n<td>Transmission &gt;80%<\/td>\n<td>Sentetik erimi\u015f silika<\/td>\n<td>Borosilicate opaque &lt;310 nm<\/td>\n<\/tr>\n<tr>\n<td>UV-Vis at 280\u2013900 nm<\/td>\n<td>Transmission &gt;90%<\/td>\n<td>Natural fused quartz<\/td>\n<td>Glass adequate but not UV-capable<\/td>\n<\/tr>\n<tr>\n<td>ICP-MS digestion<\/td>\n<td>Blank &lt;0.1 \u03bcg\/L<\/td>\n<td>High-purity quartz flask<\/td>\n<td>Borosilicate releases B, Na, Al<\/td>\n<\/tr>\n<tr>\n<td>ICP-OES digestion<\/td>\n<td>Blank &lt;1 \u03bcg\/L<\/td>\n<td>Quartz Erlenmeyer<\/td>\n<td>PTFE suitable but temperature-limited<\/td>\n<\/tr>\n<tr>\n<td>Fluorescence at &lt;300 nm<\/td>\n<td>Zero background fluorescence<\/td>\n<td>UV s\u0131n\u0131f\u0131 erimi\u015f silika<\/td>\n<td>Glass fluoresces in UV range<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr \/>\n<p><img decoding=\"async\" src=\"https:\/\/toquartz.com\/wp-content\/uploads\/2026\/02\/Quartz-Glassware-Crucible-and-Reaction-Tube-in-High-Temperature-Tube-Furnace-Setting.webp\" alt=\"Quartz Glassware Crucible and Reaction Tube in High-Temperature Tube Furnace Setting\" title=\"Quartz Glassware Crucible and Reaction Tube in High-Temperature Tube Furnace Setting\" \/><\/p>\n<h2>Quartz Glassware Across High-Temperature Synthesis and Thermal Research<\/h2>\n<p>Beyond semiconductor and analytical applications, an equally demanding set of material requirements emerges in high-temperature synthesis, thermal analysis, and photochemical research \u2014 environments where the combination of extreme temperature, reactive atmospheres, and optical access constraints eliminates conventional glass alternatives with equal finality.<\/p>\n<p>Research laboratories conducting materials synthesis, thermal characterization, and photochemical experiments impose load cases on glassware that diverge from semiconductor and analytical norms but are no less severe. Temperatures may cycle between cryogenic and 1,200 \u00b0C within a single experimental protocol; atmospheric compositions range from inert argon and nitrogen through oxidizing oxygen to mildly reducing hydrogen mixtures; and photochemical reactors require UV-transparent vessel walls that simultaneously withstand thermal and chemical stresses. Fused quartz satisfies this convergence of demands across all three contexts.<\/p>\n<h3>Tube Furnaces and Crucible Applications in Materials Synthesis<\/h3>\n<p>Tube furnaces represent the primary thermal processing tool in solid-state chemistry, ceramic science, and nanomaterials synthesis. A standard horizontal tube furnace accommodates a fused quartz reaction tube of 50\u2013100 mm outer diameter and 600\u20131,200 mm heated length, through which controlled gas atmospheres flow during synthesis, annealing, or phase transformation experiments at temperatures typically between 400 \u00b0C and 1,100 \u00b0C.<\/p>\n<p><strong>Quartz reaction tubes withstand continuous operation at 1,100 \u00b0C in oxidizing (O\u2082, air), inert (Ar, N\u2082), and mildly reducing (5% H\u2082\/N\u2082) atmospheres<\/strong> without measurable reaction with the gas phase, making them compatible with the overwhelming majority of solid-state synthesis protocols. Carbon nanotubes grown by chemical vapor deposition, metal oxide powders synthesized by thermal decomposition, and thin-film materials annealed under controlled partial pressures all rely on quartz tube integrity at these conditions. A quartz crucible placed inside such a tube serves as the immediate container for reactive starting materials, isolating the sample from the tube wall and enabling gravimetric tracking of mass changes during thermally driven reactions.<\/p>\n<p>Quartz crucibles for high-temperature synthesis are specified with wall thicknesses of 2\u20134 mm and are manufactured in volumes from 10 mL to 500 mL. Their compatibility with temperatures to 1,100 \u00b0C covers the melting and sintering ranges of most transition metal oxides, phosphates, and silicates \u2014 though molten alkali metal oxides and fluorides attack quartz aggressively and require platinum or alumina alternatives.<\/p>\n<h3>Thermal Analysis Instruments and Reaction Vessels in Research Settings<\/h3>\n<p>Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) instruments require sample holders and protective components that remain dimensionally and chemically stable across the full instrument operating range, typically \u2212150 \u00b0C to 1,600 \u00b0C in high-temperature configurations. Fused quartz sample tubes, hangdown tubes, and balance shields appear throughout high-temperature TGA instruments as both structural and protective components.<\/p>\n<p>In TGA systems, a quartz hangdown tube suspends the sample crucible within the furnace zone while isolating the precision balance mechanism from the hot gas stream. <strong>The tube must exhibit zero creep at the operating temperature<\/strong> \u2014 a requirement that eliminates borosilicate glass above 500 \u00b0C \u2014 and must transmit the gas atmosphere uniformly to the sample without reaction. For TGA experiments conducted under reactive atmospheres including SO\u2082, HCl vapor, or steam at elevated temperatures, the chemical inertness of quartz toward these species (below approximately 1,000 \u00b0C and excluding HF) makes it the default tube material in instrument design.<\/p>\n<p>In high-temperature autoclave and sealed ampoule experiments \u2014 where precursor materials are enclosed in a sealed quartz tube under partial pressure and heated to promote crystal growth or phase transformation \u2014 the quartz ampoule simultaneously functions as a pressure vessel, reaction chamber, and optical observation cell if the experiment requires in-situ monitoring.<\/p>\n<h3>Quartz Glassware in Photochemical and UV-Assisted Reaction Systems<\/h3>\n<p>Photochemical research requires reactors in which a UV or visible light source illuminates a reacting solution or gas phase with minimal attenuation by the reactor wall. Fused quartz reactors \u2014 cylindrical vessels, immersion well reactors, and flat-window flow cells \u2014 serve this function across photocatalysis, UV-assisted synthesis, and <a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/actinometry\">actinometry<\/a><sup id=\"fnref1:3\"><a href=\"#fn:3\" class=\"footnote-ref\">3<\/a><\/sup> experiments where the precise photon dose delivered to the reaction volume must be known or controlled.<\/p>\n<p><strong>An immersion well reactor fabricated from fused quartz allows a mercury vapor lamp emitting at 254 nm, 313 nm, and 365 nm to illuminate the surrounding reaction annulus with negligible wall absorption<\/strong> \u2014 transmission losses through a 2 mm quartz wall at 254 nm are typically below 5% for high-purity grades. Borosilicate glass reactors under the same lamp transmit essentially zero energy at 254 nm, confining the reaction to whatever photons penetrate the 310 nm borosilicate cutoff. In photocatalytic degradation experiments where a TiO\u2082 catalyst is activated by sub-365 nm photons, the choice between quartz and glass reactors produces categorically different photon fluence rates at the catalyst surface \u2014 a variable that completely dominates reaction rate data.<\/p>\n<h4>Quartz Glassware Across High-Temperature and Photochemical Research Settings<\/h4>\n<table>\n<thead>\n<tr>\n<th>Uygulama<\/th>\n<th>Quartz Component<\/th>\n<th>S\u0131cakl\u0131k Aral\u0131\u011f\u0131 (\u00b0C)<\/th>\n<th>Key Property Utilized<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Solid-state synthesis<\/td>\n<td>Reaction tube<\/td>\n<td>400\u20131,100<\/td>\n<td>Thermal stability, gas inertness<\/td>\n<\/tr>\n<tr>\n<td>Oxide crucible melting<\/td>\n<td>Crucible<\/td>\n<td>800\u20131,100<\/td>\n<td>Chemical inertness, thermal shock resistance<\/td>\n<\/tr>\n<tr>\n<td>TGA analysis<\/td>\n<td>Hangdown tube, balance shield<\/td>\n<td>25\u20131,500<\/td>\n<td>Zero creep, chemical inertness<\/td>\n<\/tr>\n<tr>\n<td>Sealed ampoule synthesis<\/td>\n<td>Fused ampoule<\/td>\n<td>200-900<\/td>\n<td>Pressure tolerance, optical access<\/td>\n<\/tr>\n<tr>\n<td>UV photocatalysis<\/td>\n<td>Immersion well reactor<\/td>\n<td>10-80<\/td>\n<td>UV transmission at 254\u2013365 nm<\/td>\n<\/tr>\n<tr>\n<td>Photochemical synthesis<\/td>\n<td>Flow cell, flat-window vessel<\/td>\n<td>0\u2013100<\/td>\n<td>Broadband UV transparency<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr \/>\n<p><img decoding=\"async\" src=\"https:\/\/toquartz.com\/wp-content\/uploads\/2026\/02\/Quartz-Glassware-Optical-Windows-Mounted-in-Photonics-Laser-Laboratory.webp\" alt=\"Quartz Glassware Optical Windows Mounted in Photonics Laser Laboratory\" title=\"Quartz Glassware Optical Windows Mounted in Photonics Laser Laboratory\" \/><\/p>\n<h2>Optical and Photonic Uses of Precision Quartz Glassware<\/h2>\n<p>At the frontier of optical engineering, where wavelengths extend into the deep UV and power densities challenge every material's damage threshold, precision fused silica components take on roles that no other oxide glass can fulfill \u2014 roles where refractive index homogeneity, UV transmission, and resistance to laser-induced damage are specified to tolerances measured in parts per million.<\/p>\n<p>Photonic and laser applications demand material properties that go beyond standard laboratory grades. <strong>Refractive index homogeneity<\/strong> across a 100 mm aperture must be controlled to better than 1 \u00d7 10\u207b\u2076 in the most demanding lithographic and interferometric applications; <strong>\u00e7ift k\u0131r\u0131lma<\/strong> \u2014 a stress-induced anisotropy in refractive index \u2014 must be suppressed below 2 nm\/cm in optical-grade components to prevent polarization degradation in laser systems.

At pulse energies typical of production lithography scanners (approximately 5\u201310 mJ\/cm\u00b2 per pulse at repetition rates of 4,000\u20136,000 Hz), cumulative fluences exceeding 10\u2079 J\/cm\u00b2 are delivered to lens elements over their operational lifetimes. <strong>Only high-OH synthetic fused silica maintains refractive index stability and transmission at these exposure levels<\/strong> \u2014 a requirement that has driven the development of specialized lithographic-grade silica materials with tightly controlled impurity and OH specifications distinct from standard optical grades.<\/p>\n<p>For pulsed Nd:YAG laser systems generating harmonic outputs at 532 nm, 355 nm, and 266 nm, fused silica windows and lenses replace standard glass components in the UV harmonic generation and delivery stages, where damage threshold rather than homogeneity represents the primary selection criterion.<\/p>\n<h3>Optical Fiber Preform Fabrication and Silica-Based Waveguides<\/h3>\n<p>Optical fiber \u2014 the transmission medium underlying global telecommunications infrastructure \u2014 is fabricated from ultra-high-purity fused silica preforms produced by CVD processes.

Alumina and zirconia ceramics sustain higher operating temperatures but are opaque across all relevant optical wavelengths and are mechanically brittle at the wall thicknesses required for tube and vessel geometries. Borosilicate glass covers the majority of routine laboratory applications admirably but reaches hard performance ceilings at 500 \u00b0C, 310 nm, and trace-level contamination thresholds that quartz clears without compromise.<\/p>\n<p><strong>The combination of a 1,100 \u00b0C continuous service temperature, spectral transmission from 150 nm to 3,500 nm, sub-ppb metallic impurity contribution, and resistance to all mineral acids except HF exists in no other material that can be fabricated into tubes, vessels, and optical windows at useful dimensions.<\/strong> This convergence of properties \u2014 not any single attribute \u2014 is the reason fused quartz glassware occupies non-negotiable positions in semiconductor wafer processing, UV analytical measurement, high-temperature materials research, and precision photonic systems.

Its thermal stability to 1,100 \u00b0C, UV-to-infrared spectral window, and chemical inertness to mineral acids collectively define a performance envelope unmatched by any commercially available glass alternative. Across semiconductor fabrication, analytical spectroscopy, high-temperature synthesis, and laser photonics, these properties translate into functional requirements that alternative materials cannot satisfy simultaneously \u2014 establishing fused quartz as an irreplaceable material class wherever precision, purity, and thermal margin converge.<\/p>\n<hr \/>\n<h2>SSS<\/h2>\n<p><strong>Erimi\u015f kuvars ile erimi\u015f silika aras\u0131ndaki fark nedir?<\/strong><br \/>\nFused quartz is produced by melting natural quartz crystal, yielding SiO\u2082 purity of 99.9\u201399.99% with OH content of 150\u2013300 ppm and a UV cutoff near 250 nm.

Fused quartz cuvettes transmit above 80% at 200 nm, enabling accurate absorbance measurement for nucleic acids at 260 nm, proteins at 280 nm, and aromatic compounds throughout the deep UV range. Synthetic fused silica grades extend reliable transmission to approximately 180 nm for the most demanding UV spectroscopic applications.<\/p>\n<hr \/>\n<p>Referanslar:<\/p>\n<div class=\"footnotes\">\n<hr \/>\n<ol>\n<li id=\"fn:1\">\n<p>Hexafluorosilicic acid is the soluble silicon fluoride compound produced when hydrofluoric acid reacts with silicon dioxide, explaining why HF causes rapid and irreversible etching of quartz glassware surfaces.&#160;<a href=\"#fnref1:1\" rev=\"footnote\" class=\"footnote-backref\">&#8617;<\/a><\/p>\n<\/li>\n<li id=\"fn:2\">\n<p>RCA cleaning is a standardized silicon wafer surface preparation sequence developed at RCA Laboratories, consisting of sequential immersion in SC-1 and SC-2 chemical baths to remove organic contamination, particles, and metallic residues prior to device fabrication steps.&#160;<a href=\"#fnref1:2\" rev=\"footnote\" class=\"footnote-backref\">&#8617;<\/a><\/p>\n<\/li>\n<li id=\"fn:3\">\n<p>Actinometry is the quantitative measurement of photon flux in a photochemical system using a chemical or physical reference reaction of known quantum yield, requiring UV-transparent reactor vessels through which the irradiation source delivers a precisely characterized photon dose.&#160;<a href=\"#fnref1:3\" rev=\"footnote\" class=\"footnote-backref\">&#8617;<\/a><\/p>\n<\/li>\n<\/ol>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Laboratories and fabs worldwide depend on a material most people overlook \u2014 yet without it, precision science would stall at [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":11354,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[10],"tags":[79],"class_list":["post-11352","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blogs","tag-quartz-labware"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v25.4 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>What Is Quartz Glassware?
