SP875 Algae Bloom

850-891 - Raku glazes were developed for firing in either electric or gas kilns. The firing process is described below. Eleven of the Raku glazes are lead-free and non-toxic (850,851,854,856,871,872,873,874,875,877,878). All of the rest are lead-free, but are over the threshold limit for copper and are therefore toxic in the liquid state. Liquid glazes (available in 4 ounce, pints and gallons) 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. Due to the many variables involved in Raku firing, particularly during the reduction phase, our chip charts and printed color charts should be used only as approximate guidelines. Your results may vary greatly due to different firing conditions. RAKU FIRING – Raku glazes can be fired anywhere from 1600 F up to cone 06 (1850 F) in either an electric or gas kiln. We recommend firing 850 to 856 and 868 to 879 to a peak of 1700 -
