Fredrick Paget on sat 29 dec 07
Our little valley town just outlawed our old wood stove and so we
bought a legal pellet stove and have had it running through a ton of
pellets that I bought for $280.
The pellets are said to be made of hardwood and make very little ash.
I have been saving the ash and have only about 2 gallons of it from
that half ton of pellets that we have burned so far.
The ash looks strange. It is dark almost chocolate color and I
suspect that it has charcoal in it from incomplete combustion. I will
calcine some next time I do a bisque firing to see if it goes grey.
Have not tried it yet in a glaze. Since Tozan in B.C. is down I have
not done any cone 10 or wood firing. Mostly I have been doing
research on decals - cone 013 firings.

I calcined some of the ash Sunday and it stayed the same color.
Still chocolate brown. I have never seen ash like this before.. I
wonder what is in it to make the brown.

Hi Fred,
Fire some of it to ^ 10 on a small Bisque Saucer or in a little Bowl
something, and see what it does...
They might have used some sort of Clay as a binder in making the 'pellets'
from Saw Dust, and if so, there'd be a darned near a ready made Glaze
there...

I was watching a video on Ceramic Arts Daily about a pottery that has a
pellet stove and uses the ash from it in ash glazes.
I have a pellet stove, but I've never used an ash glaze. Anyone else out
there have success with ash glazes made with pellet stove ash? How difficul=
t
are they to make/use?
Thanks!

The sawdust used for pellets are usually mixed hardwoods, so they should
work fine.
You will need to screen the ash, to remove any unburned pellets. I would
suggest final screening be through a 60 mesh sieve.
One thing to remember - when wood ash is wetted it will release solubles an=
d
you have to decided whether to wash the ash first. The wet ash can be very
caustic, so where gloves when working with the wet materials/glaze.
There are many recipes online to fit your firing temperature.
One recipe I've been starting to test is very simple:
^6 ash glaze
Wood ash - 50
Redart clay - 50
Frit 3134 - 5
I have not run this through the computer yet, so no info on
stability/functionality.

Until you are sure of your results, I'd recommend firing your ash-glazed
pots on "cookies."

Be bold and test - test tiles - shot glasses - tea bowls make better tests
50/50 (by weight) slip clay and wood ash. I fired this to cone 8 and it was
too runny. Try cone 6 or lower. The slip clay is called "Ohio Slip"
50/50 (by weight) red art and wood ash. Cone 6-10
50/50 wood ash and yellow ochre. This is supposed to be "raw" ochre. But it
use what I buy. I can't get it to flux out at cone 9 try cone 10 or
higher/longer firing
50/50 wood ash and your local red clay. You have to dig the clay then dry
and crush it, then weigh and melt it in lots of water. Get blunger (best)
attachment for electric drill or paint mixer (okay) attachment.
It's always a good idea to ball mill these kinds of glazes but screening
will help anyway.
A small 1/2 gallon pail with a lid is big enough for dipping tea bowls, but
a larger plastic bucket is needed for the mixing detail

I used them in Montana. They work like fireplace ash.
I treated them the same.

This is great advice. 50/50 ash and a few different clays, separately. I
did this with about 5 clays a year or so ago and it put me on the path
to a couple of great glazes. And a few were really nice at the outset
without any tweaking. One of them melted the cup I put it on, so you may
want to test on wadding and cookies.
One thing to try that sometimes adds interest is after you've pounded
and sifted your clay and have mixed up the 50/50 mixture, take some of
the clay left overs that you sifted out (about 60 mesh) and add little
back in to the mix. Not too much, just enough. With the higher iron
clays you'll get some nice spotting in some cases.
