May react with
Copper, silver
Cold Characteristics
Similar appearance to 1101 except it may include a slight tint of color (blue to green).
Working Notes
Easily confused with 1101. Reactive combinations have the potential to create an interface color, which may continue to develop through multiple firings. Copper-based reactions tend to be variations of deep red to black, while silver based reactions are more likely to develop as earth tones. Reactions are generally related to the amount of copper and silver content, heatwork and surface area contact. Learn more about this style in Get a Reaction.
-0031 (rainbow irid)
Strong reactions may permeate the iridized surface, finding greater surface contact through thinner sections of the irid coating (gold, silver) and minute fissures throughout. Crackle patterning is generally more open where the irid coating is thicker and transitions to dense coverage in thinner sections. Expect variation.
