List peeps,
I have a bag of Texas terracotta and a bag of grog. Will that do for some
large terracotta pieces? Grog a good filler for low for work?
Danke

we do terra cotta work using straight lizella red mixed 150 lbs clay
to 56 lbs fine grog (48 mesh???) with 44 lbs of water. this is for
ram pressing, and is probably too much grog for throwing or anything
else. haven't tried anything with it except the ram press. fired to
cone 6 looks real pretty. not sure what your texas clay is like, but
anything can be made to work.

Hey Hendrix Taylor,
When I make my own low-fire brown clays, I always add 5-10% grog,
no problemo.

I prefer sand. Grog fires as white spots and sand doesn't.

I didn't notice that with our terra cotta mix. looked pretty uniform
to me, all red. maybe it depends on the kind of grog you use?
biggest trouble we had was the electric kiln not firing off evenly,
even a 100 deg temp difference top to bottom would give noticeable
color variation - not so good when they all needed to be the same.
