Hi all and Happy New Year.
I was wondering.....what if I do a commercial glaze on a piece put it
in the kiln and before I close the lid for the last hour.....I throw
some table salt in on my pieces.....do you think that would work out
okay?.....won't hurt my kiln?......
Thanks for any advice as I am always wanting to try different things
so I won't be noted as just another "ceramic" person....I do
handbuilding (I am fairly new at this) and I manipulate my molds.....

You do not say what kind of kiln you are using, nor what temperature
you are firing to. If you are using an electric kiln, this is not a good
idea, as the fuming of the salt will affect the elements in the kiln.
Further,
even if it is a GAS kiln, "throwing in some salt" at the last minute is still
not a good idea unless you intend this kiln essentially for salt use,
are prepared for salt-impregnated shelves & kiln furniture, and are
firing at a high enough temperature for the salt to fume/react with the
clay and/or glazes. Salt as a finishing technique is generally
intended for bare, unglazed clay. It does visibly affect certain
glazes, however, most notably altering copper green glazes, so that
they may appear turquoise (Rob's Green, particularly) or various
shades of cream/gold. Salt will certainly alter the fit of many glazes,
also - expect crackling on most.
You can protect brick and kiln shelves/furniture to a significant
degree by spraying with ITC, but that is not absolute protection,
either. If you want to try salt on one or two pieces in your electric
kiln, and you are firing to a high enough temp, then you could
construct any of a variety of well-sealed saggars, place your piece
inside along with some small containers (VERY small, & pre-fired to
maturity)of salt. This can give interesting results, but I've never
achieved an orange-peel surface with this technique.

I sure wouldn't reccommend throwing salt into an electric kiln. The
damage to the bricks and elements would be significant if they were not
protected with some sort of coating i.e. ITC. You would also have to
deal with a certain amount of gases created and would need very good
ventilation if the kiln is inside.
