Hi,
Trying this to see if it goes through. It is not the glaze--and every glaze/claybody reacts differently to ash. It is the content of the soluble soda alkalies present or not present for that matter in your ash. If you want rivulets, add any feldspar--you will find the effect you like after testing different spar/ash relationships. When that tickles you, you can start adding colorants including oxides, carbonates, stains, and chromates (wear proper gear and ventilation). Good skill.

We've had good results with dry ash sprinkles - never had the problem of
grit - on Temmoku it can bleach out the colour to a yellow and if thick
enough will get some darker yellow brown black crystals like on shinos and
so can look rather attractive. However like you have not had any rivulets
anywhere. Have not tried it on any celadon yet.

Sprinkling dry wood ash on a glazed pot has been used by Tom Coleman,
Steven Hill and Dale Neese with exciting results. However my tests were
problematic. I thought that I would pass on one observation that might
save others the head ache of finding out the hard way. My work is fired
to cone 10 redux. I sprinkled sieved wood ash on a variety of glazes.
Most showed some activity where the glaze reacted with the ash, a few
showed rivulets. Malcom's Shino looked spotted like a salt glaze
effect, no running. BUT..two new glazes I tested are the reason for my
warning. They were based on the Coleman celedon Elaine Coleman uses.
This glaze has 3110 frit in it. The sprinkles on this glaze just sat
there as sharp gritty particles. Although these gritty areas were able
to be sanded, they were a flaw and provided no positive effect.
Peter Coates, in a recent post, mentioned the issue of washing ash. I
think there could be a method used whereby the ash is wetted into a
slurry and screened to take out these potentially gritty specs I
mentioned. These specs appeared to have the same characteristics of
what silica sand looks like.
So, sprinkling is a good technique to be explored, watch out for glazes
with a lot of frit in it.
Just an observation.

Hello,
I have had that problem before when i sieved through a window screen.
I usually keep some sifted ashes in the studio at the art center, but
i run them through the same 80 mesh screen i use on the glazes. Keep
some in a tub and some in a salt shaker.
