Clayart Folks,
I wanted to let you all know about a book that I just ran
across at my local library on sawdust firing. Not a lot that I can
find, is written on "state of the art" sawdust/pit firing. Anyway,
this is the best book I have run across yet. It is THE COMPLETE
POTTER-Sawdust firing. The University of Pennsylvania Press, and K.
Hessenburg is the author. It covers stains, slips, lustres, terra sig,
fuming, and lots of other neet stuff. Check it out(no pun intended.)
In the book it talks about a French artist that uses sodium carbonate
to flux his slip. Then after a bisque, he sawdust fires the piece and
the smoke gives a warm brown and tan, and a black accent where it has
crackled. A question I wanted to pose to the group is this. Has anyone
out there done this and can you tell me of a ready source of sodium
carbonate? If so, what would be the general amount to use in a terra
sig to get it to flux? Are there any health hazards related to the
use of sodium carbonate, such as with salt? Thanks again for all the
good technical info that you all share in every area of ceramics.
Jack
PS. The artist is Pierre Bayles
Spring must be here in Portland, because the rain got warmer..

Jack,
I recently purchased this book. I love it! Let me know if you run
across any other good books on sawdust/pit firing. Especially ones that
include slips and fuming.
TIA, Debi

Jack-- Sodium Carbonate is also called Soda Ash and is really common washing
(not baking) soda, sold at your nearest Grocery in a yellow (Arm and Hammer)
box.
It is a good cleaner and detergent additive, and has just the standard minor
safety cautions (" may be harmfull if swallowed, keep out of the reach of
children" etc)
The books all say that Soda Ash is anhydrous (without water) sodium
carbonate and that washing soda is the hydrated form. Since Soda ash is very
hygroscopic (sucks up water), it is hard to keep it in that form for long.
Guess what happens when you put it into a slip (ie, add water)--
Bill- sitting in a hydrated (ie, it's raining) atmosphere, on Persimmon Hill.
