Also has a nice effect if you re-fire in ^6 oxidation after soda, it turns almost solid olive green with micro-crystals. The woman at Teance asked for me to do that with the bowls they bought. Personally, I prefer the teadust. My clay supplier has his own teadust that I have been begging him to mix again, but he won't and he won't give me the recipe and won't sell me his remainder and he won't use it himself.... ARRRrrrrrghhhhh.
^10 Soda then ^6 oxidation is a lot of firing for one piece!
If you are firing ^10, there are a few tea dust recipes in John Britt's book: http://www.johnbrittpottery.com/pub.htm
I also use a variation of a tea dust based on an amber celadon recipe. Although the results are much better when used in a non-soda ^10 over a high iron body.
Regarding soda introduction -- I use a Nichols based method: wood shavings, soda ash, soda bicarb, whiting, mixed with water to a tuna salad consistency dumped via angle iron over fireboxes. Works pretty well...
