So does this mean I can make a solution of soda ash and control the carbo=
n
trapping? What do you mean by hot?
Why then does one of my formulas without it trap carbon (it has borax)?

Sorry for all the questions but I had never heard of shino until about a
year ago (I've only been potting for ten years, just a pup). chris

It is about soluble salts being left on the surface of the piece as the
water dries. Both soda ash and borax are soluble. Thus, the effect of
wax is to retard the buildup of salt scum, because the water goes around
the wax to get to the surface of the piece, leaving the scum around the
wax but not so much underneath it. The longer you leave the piece out
of the kiln, the more the soda ash scum builds up. I like to fire the
pieces within a few days, to get a balance between the scum and the
balanced shino.
