In the post Ash glazes in time of potter’s life I wrote about walnut shells ash waiting to be tested as a glaze and it seems, that the time has come.
Why we use ash for glaze? The answer is quite simple, it contains (in most cases) all oxides needed to produce glaze. It is much easier ingredients to obtain - to understand this statement consider the amount of work involved in turning silica stone into silica powder and burning for example rice straw, which has quit large amount silica in its ash. It is pure fun to see unravel what is nature hiding.

Burn walnut shells... and then be surprised how small amount of ash you get from a large amount of walnut shell....
Add water and sieve all the ash through glaze sieve.... Let it stand and then pour some water out ... Glaze should be on yogurt thickness. Glaze and fire...

Very interesting! How does it come that the glaze is so dark? Does the glaze contain Iron?
ReplyDeleteYes Luke, Iron - oxide, which is in same time the most loved and most hated by potters. Loved for the possibility of many colors it offers and hated, when you trying for white glaze.
