Yes, it will probably all turn black or gray, depending on how much air it gets. You will see more color if you allow more air to enter the kiln or your firing chamber.
I'm making a primitve piece, where it is burnished then decorated and high smoke fired, I was wanting to use natural eastern sandstone ground orche on some parts for color, will it work? will the smoke fire, just turn it black?
nice firing!! I turned an old alpine updraft into a soda kiln a few years back, and it gave me wonderful results. wasn't sure what to expect from an updraft, but I was pleasantly suprised!!!
We did that too, using an old Alpine, a few years ago at a school where I was teaching a class. We put the soda into the burner blower unit and it spread it pretty well around the kiln. I think that the down draft kiln is a little better for soda firing though.
Does the soda firing impart any kind of taste to the ware? I bought a salt-fired mug at a craft fair once and was shocked to taste what it did to a cup of coffee. Is salt firing the same as soda firing?
No, there should be no taste from the glaze as the result of soda or salt firing. The difference is, in a salt firing salt is used (NaCl) and in a soda firing baking soda or soda ash are used (NaHCO3), but the result is sodium silicate which is an insoluble glass and has no taste. I suppose the interior of the cup, which is generally a different glaze, could have a slight taste, but that is very unlikely. Wash it very well and try it again. If you still find there is a taste, discard the cup!
