Spectrum's Raku glazes were developed for firing in either electric or gas kilns. The liquid glazes are set up for brushing application. They can also be poured or dipped on pieces, although they should probably be thinned with a little water for this type of application.
Raku glazes can be fired anywhere from 1600°F up to cone 06 (1850°F) in either an electric or gas kiln. They should be allowed to cool in the kiln to 1600°F. Different combinations of peak temp and reduction starting temp will produce different results.
Due to the many variables involved in Raku firing, particularly during the reduction phase, your results may vary greatly due to different firing conditions.
Cosmic Copper is lead-free and non-toxic.
