My Italian Grandfather died last week. This was no ordinary man. He lived
on the streets at the age of 8 due to a family tradgedy and danced on the
streets survive. He was a character to say the least.
I have been asked to create medallion keepsakes with ash mixed into the
claybody as well as possibly the glaze. I am thinking of rakuing them with
a wire armature to hold the medallions as this is the most immediate means
for me before the "celebration."
I have never used human ash before and am curious to what percentage, if
any, added will have any detrimental effect on the claybody? I have some
recipes that use bone ash and am thinking a straight substitute should pose
few if any problems. Any suggestions or insights appreciated.
Also, does anyone have a molding raku claybody slip recipe. I will either
make the medallions by hand or mold/slip them--whatever looks best and
glazes nicely.
Thank you.

Dear Tony,
Sorry for your loss. It sounds like your Granfather was a cool old dude.
(Grandfathers are generaly, by nature, cool old dudes)
I like your project. Neat way to memorialize him.
Years ago, when we first started doing raku, we made up up large batch
of "raku slip", as we had a bunch of molds around, and wanted to try
slipcasting forms for glaze testing.
Sorry to not have a recipe per sey, but we kept it simple, and it worked
fine. All we did was took a bag of stoneware, tore it into little chunks,
slaked it down in hot water. We were careful to not use much water. Hit
the bucket with a paint mixer. Made a real thick slip. Added a little
(be careful, too much is very bad) sodium silicate to defloc. Adjusted
with more water. Did it by the seat of my pants. Worked out fine.
I remember that the only problem was getting it TOO deflocked, and the sand
would setle out. If you were to try this with a grogged clay, probably the
same problem.
I know that Laguna used to produce a "Raku slip", but that was several
years ago, and I don't know if they still do. It sounds like you don't
have time to wait for an order anyway.
I'll be interested to see if anyone else posts a real "recipe".
Good luck, and again, sorry for your loss.
Best Regards

I have done raku using a standard commercial
^10 slip, bisqued to ^04. Worked pretty well.

Besides adding ash to the clay body - why not add it to the raku glaze?
