Ash Glaze results                                             
The 4 samples below were different batches of ash mixed with water, showing that the ash creates a glaze on it's own.

Ash from carob tree (A)

Ash from log fire (J)

Ash from leaves etc (S)

 

Mixed ash from bakery which included lots of nails (B)

We then mixed 50% ash with 50% other ingredients found in the pottery

50 ash (B)+ 50 dolomite

50 ash (C)+ 50 zinc oxide

50 ash (J)+ 50 nepheline syenite

50 ash (S)+ 50 borax

50 ash (C)+ 50 talc

50 ash (A)+ 50 potash feldspar

50 ash (C)+ 50 soda feldspar

50 ash (B)+ 50 whiting

50 ash (B) + 50 china clay

50 ash (C)+ 50 cornish stone

50 ash (A)+ 50 coleminite

50 ash (A)+ 50 lithium

Some of these results would make a good glaze, The dry ones would be good for more sculptural pieces. Advantage can be taken of the halo that some of the ingredients give and would be good for wax resist decoration.
