Cosmic Copper 878

Spectrum’s 850 Raku Glaze Series can be fired in both electric and gas kilns and are available in a variety of unique colors. These glazes will allow you to create exciting and amazing effects!

Spectrum's Raku glazes are all lead-free and require a Raku firing process to achieve the results shown. Pieces are fired to 1750 degrees F (950 degrees C). While still red hot, the glazed piece should be transferred into a reduction bin; commonly a small sealable metal container containing organic material The bin should then be closed and the piece allowed to cool before removing and cleaning it.

Raku firings typically produce very variable results, so the test tiles are only provided as approximations. We recommend testing all glazes first.
