Working Notes

Torch: Black Opalescent Rod (000100-0576) remains black except in extremely thin applications, when it may become dark gray. It is a soft glass. Beware of heating the glass so much that it bleeds and webs out over other glasses‚ or use this quality as a design element. Consider using Stiff Black Opalescent (000101-0576) for a crisper appearance.

Kiln: Working properties and kilnformed characteristics are consistent with sheet glass. See sheet glass notes for this style.
