Mighty Moss features newer aventurine technology, which has greatly improved the stability of glitter boro colors. This glass is a very densely saturated aventurine with large, dichro-like sparkles. Limit the time you “garage” your work, do not go above 1050 in the anneal cycle, and anneal as short a time as you can for the size of the piece. Not sensitive to flame atmosphere, but reduction should be avoided on aventurines before implosion.
