About this category. Colour in hot glass is a compatibility problem before it is an aesthetic one. Every colourant carries its own coefficient of expansion, and a colour that does not match the base glass will craze or crack the piece weeks later. Match COE first, then worry about the palette.
Specifications are published ranges and vary between manufacturers. Always follow the equipment maker's own instructions and safety documentation.
