I recently tried sawdust firing and got only mediocre results. I'd
appreciate any answers to these questions:
1. I used hamster bedding as I understood that the sawdust should be a mix of
coarse, fine and some shavings. Could this have been too coarse?
2. I used two experimental pieces, a bisqued raku-ware and a bisqued red
stoneware. I put them in upside down. The insides came out beautifully
black..the raku even had a touch of a deep velvety blue...but nothing on the
outside at all! Why?
3. Can I do it again to the same pots? What if I glaze and fire them (eg.
raku the raku piece, and glaze fire the stoneware to cone 6)?
4. Any other good advice?

It has been my experience that hampster bedding is too coarse therefore the
fire burns very quickly and doesn't get hot enough. I have had better
results using all sawdust.

I always have used a buff earthenware with extra grog. The buff claybody
excepts the reduction from the fire and the extra grog helps with thermal
shock.

I have found that when I sawdust fire a pot a second time it increases the
chance of it cracking.

Hope this helps,
Wayne Bien

I get sawdust from a dust collector at a local cabinet maker's shop.
Wear a mask when collecting. The dust is fine to coarse, hard woods with
little tar. Fires great.
