The following are select filters and frames for those artisans who are engaged in torchworking (aka lampworking) borosilicate glass, including Glass Alchemy, Northstar, Momka, or any other borosilicate glass with a COE of 33. For information about the specific filters listed, please click on the filter label that heads each column. On those links, you will find information about the filter as well as transmission charts for each filter.
Developed as a low cost alternative to the full coverage AGW®-250 filter, this lens will knock out all competitors products. It meets or exceeds all applicable ANSI standards. While mainly designed as an entry-level borosilicate filter, it is also useful for knocking down the bright flare that occurs when working silvered soft glass. The AGW-203 filter is a "full coverage" filter, approximately a true shade 3.5 welders filter. It is 20% thinner than competing filters and with similar savings in weight, this filter takes the pressure off your nose. Lenses are available in plano (non-prescription), readers and single vision lenses. Clip on's are available in this filter. Protected under United States Patent Number 6,612,697. Specifications: Maximum Visible Light Transmission: 12.4 % NOTE: This filter is *NOT* designed for advanced techniques such as fuming, or with intensive flare colors without additional filtration such as our 7520 welders clip on flip up. |

The AGW®-250 lens was developed to answer requests for even better ultraviolet and infrared radiation protection while also reducing the light level perceived by the eye. It consists of a base lens of AUR®-92 with a thin layer of either shade 4, 5, 6 or 8 Green Welding (full coverage) cemented to the base lens. This is very desirable when working with high pressure torches and glass requiring very high temperatures. Suggested uses are: where there is a need for attenuation of bright illumination, such as that generated when working Pyrex®, quartz, Vicor®, platinum jewelry work, and any operation where long periods of time are spent gazing into a high temperature furnace or fire pit. Quartz workers must use a minimum Shade 8! Lenses are available in plano (non-prescription), readers and single vision lenses. Clip on's are available in this filter.

Specifications (Shade 4): Maximum Visible Light Transmission: 11.2 % Specifications (Shade 5): Maximum Visible Light Transmission: 5.7 % |

You asked, and we answered! This lens is the latest in our catalog for the best protection of infrared and ultraviolet radiation. The lens consists of a base of our AUR®-92 filter with a section of Green Welding (Shade 4, 5, 6 or 8), and a section of Green Welding (shade 2, 3, 4, 5 or 6). You may have your lenses made half and half or one third/two thirds. The shades in standard configuration are light on top and dark on the bottom. The reversed configuration (custom made, not returnable) is dark on top and light on the bottom. Your choice. The available shade configurations are:
This filter is particularly valuable for use in fuming and other tasks where the brightness of the flame is a problem. It will also lend itself to most borosilicate glass work where larger sculptural work is done. By tipping your head you can change the shade number you are viewing through as the brightness of the glass changes. Cip on's are NOT available in this filter. Lenses are available in plano (non-prescription), and single vision only. Shade 4 & 5 Transmission Chart Protected under United States Patent Number 6,612,697.

This filter is an enhanced version of the AUR®-92. It has added infrared absorption that the AUR®-92 does not have. The AGW®-300 is a revolutionary new filter designed for hot glass workers that are working at the furnace doing gathers and gazing into firepots as well as scientific and artistic glassworkers who are doing work with clear borosilicate only. This is also an excellend filter for the metal worker who needs high visible light transmission coupled with excellent infra-red (heat energy) filtration as well as sodium flare filtration. Soft glass workers will also find this filter useful to remove the heat energy that you are exposed to while working with large torches and/or large pieces. The AGW®-300 is a laminated filter with the same transmission characteristics of our original AGW®-186 filter. It consists of a base lens of AUR®-92 and a thin layer of our exclusive lightly tinted IR filter glass. The filter has very good visible light transmission, averaging 60 to 70%, with excellent absorption of the sodium flare. Suggested uses are: High pressure torches and temperature applications on hard glasses like Pyrex®, and Vicor® where high visible acuity is required along with filtration of high amounts of infrared radiation. Clip on's are available in this filter. Lenses are available in plano (non-prescription), readers and single vision lenses. Protected under United States Patent Number 6,612,697.

The AGW®-325 lens was developed to answer requests for even better ultraviolet and infrared radiation protection while also reducing the light level perceived by the eye. This filter replaces the traditional AGW-286 filter. It consists of a base lens of AUR®-92, a thin section of our exclusive lightly tinted IR filter glass and a section of either shade 2, 3, 4, 5, 6 or 8 Green Welding cemented to the base lens. You may have your lenses made half and half or one third/two thirds. The shades in standard configuration are "clear" on top and dark on the bottom. The reversed configuration (custom made, not returnable) is dark on top and "clear" on the bottom. Your choice. The available shades are:
Suggested uses are: where there is a need for attenuation of bright illumination, such as that generated when working Pyrex®, quartz, Vicor®, platinum jewelry work, and any operation where long periods of time are spent gazing into a high temperature furnace or fire pit. Clip on's are NOT available in this filter. Lenses are available in plano (non-prescription), and single vision only.
