May Glaze : Forbes Sassy Fat White

With Silver Nitrate added I call this glaze Silver Slither, which is pictured.  This glaze has to be fired hot to about 1950F for the platelets to form beads.  it looks different on top of a variety of base glazes as you can see from the photos.  Works best on shoulder of pieces or on a more horizontal surface.  Mix on the thick side.  I usually apply a very small amount at a time by either pouring or brushing.  When I pour it, I often will blow on it to move it around.

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).
