Glassblowers who work with quartz require different eyewear than those who work with pyrex or art glass. The reason for this is that quartz has a higher melting temperature than art glass, and does not emit yellow sodium flare. Unlike most other scientific glass and art glass, which emit some level of sodium flare under a torch, when working with quartz, the primary concern when shopping for safety eyewear is protection from infrared radiation and the brightness of the torch.
However, there may be situations where quartz workers use other materials as part of a larger quartz piece. In such cases, they typically require eyewear with a different lens to provide the necessary protection.
Phillips Safety offers a wide range of top-quality glassworking glasses, both for lampworking and for glass blowing. Our glassworking glasses are suitable for any type of hot glass application, whether for artistic or scientific purposes. All of our lenses are made of optical-quality German glass, and our plastic lenses are engineered to provide the best VLT (visible light transmission) in their class.
Our hot glass eyewear offers IR, UV, and sodium flare protection in different shades and combinations, ensuring that you get the protection you need. We offer several filter options for soft glass and borosilicate glass, as well as different types of work, such as furnace work, small glass work, and large glass work. Most filters also allow for mirror coating add-ons.
For lampworking, Phillips Safety offers dozens of eyeglasses options with the following filters: Phillips 202, Sodium Flare Poly, BoroView 3.0, BoroView 5.0, BoroTruView 3.0, and BoroTruView 5.0. For glass blowing, multiple eyeglasses are available in the Light Green filter.

When working with quartz, the high melting temperature results in the release of dangerous infrared (IR) radiation from torches, which is invisible to the human eye. In contrast, scientific glass such as borosilicate releases sodium flare along with infrared radiation. In such cases, our Sodium Flare Poly lens, commonly known as didymium or rose glass, is the most suitable lens choice.
Since many quartz pieces involve other types of glass, our quartz working glasses are designed with split lenses that feature a lighter lens on top and a darker green lens on the bottom. This design ensures maximum protection against both infrared and sodium flare.
Regarding the top part, which accounts for â…“ of the entire lens, it is available in three options: clear glass, sodium flare poly, or green welding. The sodium flare poly lens provides protection against UV and sodium flare, appearing as a bluish-purple tint. It has a moderate shading level, with a visible light transmission of 23.5%, and provides little protection against IR. The â…” of the bottom, on the other hand, are available in green welding lens, in either shade 6.0 or 8.0.
Besides the quartz working glasses with split lenses, Phillips Safety also offers a variety of options with shaded IR lenses. IR shade lenses are specifically designed to protect against infrared radiation, which is emitted by high-temperature sources such as welding torches or furnaces. At Phillips Safety, these glasses come with lenses in a variety of shades, ranging from 4.0 to 8.0. They offer excellent protection against eye damage and can help prevent conditions caused by prolonged exposure to infrared radiation.
Selecting the right lens for your glassworking or quartz working needs is crucial for maintaining eye safety and achieving optimal visibility. It is essential to consider factors such as the type of material being worked with, the temperature involved, and the level of protection needed against UV, IR, and sodium flare.
Phillips Safety offers a wide range of lenses, including split lenses and various filters, to cater to the specific requirements of different glassworkers and quartz workers. Choosing the right lens may take some trial and error, but the effort is well worth it to ensure a safe and productive work environment.
