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).
