Spectrum Raku Glazes / Cone 06-04
	WARNING! RAKU IS AN INHERENTLY DANGEROUS PROCESS AND PROPER SAFETY PROCEDURES SHOULD ALWAYS BE FOLLOWED WHEN RAKU FIRING!
Click here for Raku Safety Equipment. For books about Raku, click here. Raku glazes were developed for firing in gas kilns. The firing process is described below. All but three of Spectrum Raku glazes are lead-free (857, 858, and 867 contain lead and cadmium). Four of the Raku glazes are lead-free and non-toxic (850, 851, 854, and 856). All of the rest are lead-free, but are too high in copper concentration to be considered non-toxic in the liquid state. Spectrum 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. Spectrum dry glazes are set up for dipping application. Please follow Spectrum's "Dry Glaze Mixing Instructions” for mixing procedures and amount of water required. Spectrum® Raku Series glazes can be thinned with water. For detailed suggestions regarding how to adjust the set up of a dipping glaze please click here for Spectrum's “Guide to Adjusting Glaze Viscosity and Density”.

Due to the many variables involved in Raku firing, particularly during the reduction phase, our chip charts should be used only as approximate guidelines. Your results may vary greatly.

RAKU GLAZES
Raku glazes should be fired between Cone 011(1600° F) to cone 06 (1850° F) in a gas kiln. Spectrum recommends firing #850 ~ #859 to a peak of 1700° F ~ 1750° F and #860 ~ #867 to a peak of 1600° F ~ 1650° F. Then 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. While still red hot they should be transferred as quickly as possible into a reduction bin (typically a metal garbage can or small metal container with a lid that has been lined with organic material, such as newspaper and/or sawdust, etc.). As soon as the pieces are in the bin the lid should be put on to keep oxygen from entering the container, in order to develop the reduction atmosphere. The pieces should be allowed to cool in the bin for at least 20 minutes. When the red hot pieces go into the bin the organic material ignites producing flames and smoke, so this part of the firing, particularly the opening of the reduction bin, should be done outside in a well ventilated area. Proper protective clothing and tools must be used for safety.

Try to size the reduction bin to the size of the piece

Position the organic material (newspaper, sawdust, etc.) and the piece so that the flames can get all around the piece.

Different organic materials can produce very different results, so for example a glaze reduced in newspaper could be a beautiful blue color and the same glaze reduced in sawdust could have a metallic copper appearance.

Pieces should be cleaned immediately with water and a hard bristle brush.

After cleaning; warm the pieces in the kiln to evaporate any water from the piece. This helps to set the colors more permanently.
