This month's glaze is a revision of my March Glaze called Lime Green Crackle. Stay tuned for a silver glaze recipe next month!

This glaze is fired to 1900 degrees F, pulled from the kiln and reduced in a small can with newspaper.  Lid is put on immediately. Wait about 2 1/2 minutes and remove the lid.  Rub the top of pot with torn newspaper using gloves.  Once paper ignites cover can again immediately and let cool (you may have to use a torch to reignite the paper).

RAKU POTTERY GLAZE RECIPE

Frit 3110                     54%
Nepheline Syenite    21%
EPK (Kaolin)               10%
Silica                           10%
Lithium Carbonate     5%
Add:
Chrome                       .4% (that's point 4)
Tin                               3%
Hectorite                     2%  (or 1 Bentonite dry mixed)

A note about Hectorite:  It's a suspender in powder form similar to Bentonite except it doesn't have to be dry mixed with the other chemicals.  It's not a common raku pottery glaze chemical and you may have to search for it on the web. I purchased mine at Highwater Clays, but they don't carry it anymore due to lack of demand (nobody knew what it was used for).
