@pyroclayman thanks for watching. the ash is mostly oak. just what ever comes out of my woodstove. the red clay is an italian clay colorbbia. i think? my supplier had it laying around. i use it for my black iron slip. but any lowfire red clay will work. the clay was standard 205 and 182 (white) but the glaze comes out the same on both. i am going to experiment a little with china clay instead of the red clay just to see what happens. i also tried volcanic ash but didn't run but a midnight blue
Nice work John. I too am a Simon Leach fan. Hope you might help with two easy questions. What was the tree species for the ash, and what was the red clay you used? Thanks.
from what i've read, you can try combinations of wood ash:clay from 25:75, 50:50, 75:25, just do some tests first. also, you can add some epsom salts to the glaze to better suspend the ash in the glaze.

Gracious of you to give Simon his due. It is great to see accomplished artists sharing information and not letting ego get in the way. Claire

Awesome! Thank you, been looking for an easy glaze for bushcrafting primitive pottery.
Yes I saw that video and was pondering. It may be more complicated at cone 6 oxidation. Nice results for you. Thanks Jeff
Cool results on the ash glaze.
They turned out nicely.

Thanks.
i just love your videos :)
I like the glaze finish
I'm wondering which wood ash glaze it is. Can you tell me the recipe? Also, did you wash the ash first?

I watch Simon, he can turn out some nice stuff. Yours is very nice.!
is wood ash and possibly and possibly the 50/50 wood and red clay glaze viable for an electric kiln? would love some feedback to attempt at school
Nice pitchers! Janice
What cone do you fire these at?
well done..
These were fired at cone 10 with ash glaze will only work at cone 10
unfortunately true ash glaze Will only work with Cone 10
what is the difference between slip and glaze
Most Slip is made from clay
@potteryworks Did you ever try the cobalt to the ash glaze? If so, what were your results?
What firing temperature?
Cone 10
Come 10
