Is anyone using Standard Clay S105, grogless white earthenware? I buy mine =
from
Ceramic Supply in Lodi NJ. I have been looking for a low fire clear recipe =
that
will not yellow or craze on the S105 and works over Amaco underglazes.
Currently, The commerical Duncan Clear is OK...but would prefer to mix my =
own as
the Duncan settles out and cost to much, for the ten gallon buckets. I've =
tried
many different types ..all with one problem or another. Thanks for any =

how about a cone 04 that isn't too hard to make. my notes remind me of
this....Transparent Flowing glaze 04^ lead frit transparent gloss. Seg 42 if
you have Caly and Glazes by Chappell
Lead bisilicate 76.5%
Kaolin 8.%
Neph. syenite 15.5%
and there you have it , to quote a sailor friend of mine about my glaze
recipes I use,"I likes mine simple". Good luck and God's speed. Your fellow
potter Douglas Adams!

Hi, Lisa...I used Standard 105 for years for miniatures, and I used
Standard's LEADED 06 clear glaze - over sponged cobalt slip for
spongeware repros or just as is - and that was fine, since I was dealing
with very small amts of glaze and a scale even a mouse would not be able
to eat out of! I did try Standard's leadless equivalent and found that
it tended towards cloudiness and any colors I tried underneath seemed
blah except for cobalt.
Somewhere I read that strontium carbonate could be substituted for lead
in low fire glazes and give good coloration and not be subject to all
the flaws of high alkaline glazes. I have fooled around with some
tests which showed promise, but I've never tried any direct
substitutions. Either you will have to spend some time on
experimentation or one of the other clayarters will have a super recipe
for you out there. (I was going to do some repros of redware and
slipware for actual use by museum people, but I left the repros behind
with the days of college tuition and never did finish the
experiments.Sorry I don't have more definitive advice. Cheers, Carolyn
