Thanks for the advice about air shutters on venturi burners, folks. Clayart
has qualified for the second oddball round:
Today's query number 1 relates to a gallon of sodium silicate I unpacked
from the detritus of my last ceramics avatar, which has now become a solid
white mass under a clearish liquor (the sodium silicate, not my avatar).
Any guesses as to what might have precipitated out over the last ten years
or what might remain in the liquid form? I was thinking maybe toss it on
some shinos to trap the wily carbon, but that'll be a waste of time if
that white's all the sodium something that fell out of solution. Whatever
it is, what might I use it for beside landfill?
The tougher Q number 2: what to do with forty pounds of graphite from the
same trove? Every time I move, I get it all over me and spitefully, I want
to try it by fire. I'm not optimistic - it'll probably only burn off with
a sneer. But maybe it could serve some kind of stirring function as it
evanesces, like zinc in reduction glazes? Or work as an oxidation agent as
a brush-on and infuse shinos with the carbon that I didn't get from that
stuff in question number 1? Please help - I don't want to grapple this
stuff again.
Jeff
