What is Quartz Glass/How is Quartz Glass Made?

Quartz Glass Sheet

Quartz glass is made of a material called pure silicon dioxide that is known to endure harsh settings.

Quartz glass is mostly used in electrical parts, lenses, and the medical field such as MRI machines and surgery tools. One of the benefits of using quartz glass is it is durable and lasts for a long time — one of the many reasons why many industries prefer to use this kind of glass.

We will cover everything about quartz glass manufacture in this post, from its definition to its procedure.

What is Quartz Glass?

Quartz glass, often called “fused silica”, is made from pure silicon dioxide, the main component of sand.

In order to produce quartz, sand must first be purified before being melted at high temperatures. Quartz glass was discovered in the mid-19th century and utilized in numerous industries.

How is Quartz Glass Made?

Here’s a step-by-step process of how quartz glass is made:

Selecting high-quality quartz sand

This first step involves selecting high-quality quartz sand for purity purposes. This sand is the primary raw material in creating the quartz glass.

Melting in electric arc furnace

The selected sand is placed in an electric arc furnace. The furnace uses electrical currents to generate high temperatures that melt the sand.

Formation of glassy material

The heat transforms the sand into a glassy, material. This process also creates small bubbles in the material that scatter light and give quartz glass its characteristic opacity.

Cooling to form glass ingots

After the molten quartz cools down, it forms large blocks known as glass ingots. These ingots are the basic units from which various quartz glass products are formed.

Crushing and molding of the glass

The ingots are crushed and molded into different shapes and sizes to meet the requirements of the industry/client. Take note that the manufacturing process also depends on what industry requires the quartz glass.

Drying and sintering of the glass

The next step is the drying and sintering of the quartz glass. Sintering uses heat or pressure to improve the durability of the quartz glass.

What are the Benefits of Quartz Glass?

High-temperature resistance

One of the benefits of quartz glass is its durability and resistant quality to high temperatures. Since this glass is heat-resistant, quartz glass is often used in industries that involve the use of heat such as electronics, optics, medical and more.

Optical transparency

Because of its transparency in ultraviolet and infrared spectrums, quartz glass is a good material for optical applications. It means that quartz glass is well-suited for making lenses, prisms, mirrors and other optical components.


Quartz glass is cost-effective and low maintenance compared to other materials, making it an ideal choice for a variety of industries.

Industries that Use Quartz Glass

Quartz glass is used in a range of industries and applications, such as:


Quartz glass is durable and heat-resistant, making it useful in electrical components. Quartz glass is used in wire, semiconductors, capacitors, and other high-temperature components.


Quart glass is used in the medical field as it is seen in MRI scans, lasers and other medical devices.


Quartz glass is used to make optical fibres, lenses, prisms, and mirrors due to its ultraviolet and infrared transparency. It also measures optical device temperature rise.

Solar Energy

Solar cells require quartz glass as protection against harsh weather conditions such as dust and moisture. The silicon dioxide in quartz glass makes it a material that is strong and can withstand intense temperatures.


Because of its durability and strength, quartz glass is often used in making chemical equipment. Quartz glass can withstand the corrosive effects of chemicals which makes it a good material for laboratory apparatus like beakers and flasks.

The Future of Quartz Glass Manufacturing

The rise of quartz glass will be in demand in the near future as we progress in a world where industries use quartz glass.

The growth of industries such as electronics, medical equipment, and renewable energy, which heavily rely on quartz glass, will also fuel the demand.

Please note, that ongoing research in materials science may find new applications for quartz glass, expanding its usage in sectors we can only imagine today. Hence, the future of quartz glass manufacturing looks bright and promising.
