True Didymium™ Sheet Filter Glass

True Didymium™ is our exclusive soft glass torch working filter. It is an updated recipe for the old Schott ACE glass. We do not source this filter from Schott but from one of their competitors. 

A side benefit of this filter is the apparent improvement in judging the color temperature of the glass while working it. The observed color is extremely comfortable when viewing glowing heat sources for prolonged periods of time.

The sheets are available in 100 mm (4") square. 

These glass sheets are not tempered and will break or shatter if mishandled. We have beveled all edges and corners.

DO NOT expose these sheets to direct torch flame without additional heat filtration. Keep the sheet at least 6" from the flame. Use care when mounting the sheet in a bracket so that screws do not pinch or grip the sheet without cushioning.
