Craig,
"Glad to hear that a slooow bisque solved your pinholing problem, that =
was a very EZ fix.
I will bite on your orangepeel offer, what is the secret?"
Well, I guess the secret is Tucker's MidCal5, a simple metal oxide =
brushed on while the pot's wet or leather hard, Hansen's 5X20, a lower =
temp fired bisque (^07) at a pretty fast rate (>150F/hr between 1000 and =
^07) and a quick-ish high fire to ^6 (when I used the Skutt computer's =
medium rate with its ramp rates, the nicest orangepeel occured, but the =
Skutt slow fire automatic rate to ^6 works well too), all done in =
oxidation of course. Cobalt Ox and Manganese Ox are very stunning with =
the orangepeel. It's a nice texture and glossy. Wish it were what I =
was trying for but, I need smooth.
I'm pretty sure that the Tucker clay has to be the key ingredient. I =
have no idea why, being as how my knowledge of clay and glaze materials =
is less than that of a fruit fly (with apologies to fruit flies). I =
just know I like the Tucker's in orders of magnitude over any other clay =
body I've ever used. And, you're right, the fix was a much needed (for =
me) no brainer.

And as we talked about at Rosen....the thickness of the glaze
application may be having some effect here. Thinner application gives
somewhat of an orange peel effect when the clay body texture shows
through.
