Bracker's Good Earth Clays Bracker's Crackle White dry raku glaze
The picture for this item is just one example of the Raku Crackle White glaze. This is technically a clear glaze (there's no opacifier in the recipe), but everyone refers to it as Crackle White. Feel free to experiment with underglazes, stains, and even non-raku glazes underneath this Crackle White glaze. You can also add stains or chemical colorants (like cobalt oxide, copper carbonate, etc) for dramatic results. You might really enjoy the experimentation! As of Sept 29, 2023 this has been converted to use Gillespie Borate as Gerstley Borate is no longer available. Mixing instructions: mix with water at a 1:1 ratio (pint of water to a pound of glaze) and apply two coats.

Laguna R13 Copper
A spectacular metallic, iridescent glaze that produces a myriad of colors including: maroon, gold silver, blue, red and copper. Best when applied medium to thick. Observations by Cindy Bracker when using this glaze: "I was blown away by the deep blue-greens blending into yellows, and subtle golden metallics that edge toward magenta & purple when reduced in Excelsior. With leaves as the reduction material, dark greens edging toward silvery-metallic was predominant, while the sawdust provided more of the results I expected – flashy copper metallic with the deep purple and blue iridescent tones. Laguna’s R-13 Copper has earned itself a spot in my regular repertoire of Raku glazes."

Spectrum Glazes Inc 890 Chimera Raku Glaze
Due to the many variables involved in Raku firing, particularly during the reduction phase, 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: Spectrum 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 - 1750°F and 860 to 866 to a peak of 1600 - 1650°F. 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 lidded metal garbage can or small metal container 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. WARNING: When red hot pieces go into the bin, the organic material ignites and will produce flames and smoke. This part of the firing, particularly the opening of the reduction bin, should be done outside. Always take safety precautions when firing raku such as the use of high temperature gloves, protective eyewear, and a respirator. Always have a fire extinguisher handy. FIRING TIPS Try to size the reduction bin to the size of the piece. Establish a good seal to the reduction bin so that air is not entering and smoke is not leaving the bin. Position the organic material ( newspaper, sawdust, etc.) and the piece so that the flames can get all around the piece. Different organic materials may produce very different results, 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.
