Hi Randy,

I posted this info on Ash Glazes quite some time ago. I am pasting what I wrote to Mike at that time. There is other interesting info there if you look up the tread. Here is what I answered at that time.

Hi Mike,

I have dug out the original old recipe from The Craft of the Potter (Michael Casson UK potter extraordinaire, sadly passed away). He fired high temp but I liked the dry ash texture and tried to lower the temp. 

Original Recipe

Ash          50

Ball Clay    25 

Kaolin       25

I don't know if he washed his wood ash, I don't. What I do is put it thru window screening ridding of big chunks and then put it thru 80 to 100 mesh. 

My starting recipe is:

Ash                        23

Whiting                   16

Feldspar

or Nepheline Syenite  13

Ball                         48

Iron oxide                 5 / 10

Bentonite                  2

Then I test it and usually I have to tweak it to my liking (more flux perhaps). I fire higher than 6 more in the cone 7 range and hold it for 30 min at high temp. I have also played with firing down at 1800F to 1600F holding it at 1700  for awhile.  Leaving out the iron oxide to work with the base and adding other possible oxides could be pursued of course. It is a glaze that works best on outside of functional ware with a liner glaze on inside. Hope there is something here for you.

Joan I am interested in your outside glaze.  Can you share it with us?
