Marigold Yellow Opal Frit (320)
Contains sulfur and reacts to copper glasses. May react to silver. Marigold Yellow is a striking glass. Striking glasses are those which, when in their cold state, do not display their target color. They must be fired and held at 1225 degrees for a period of time before reaching that target color. This style can opalize and/or become incompatible when held at high temperatures for an extended period.
