Subject: 06 glaze on vitrified cone 6 body
Has anybody tried putting low temp glazes (cone 05-06) on=20
a cone 6 clay body that has been fired to maturity (with no glaze)?
Brushing the glazes on and getting them thick enough is not a problem.
The problem is the glaze is shrinking and the body is not,
causing a dimpling and thinning which, with red glazes, turns dark.
I know,I know, why would you want to do that?
There's a bunch of good reasons that I don't want to bore the list with.
I am wondering about spraying a light coating of a low temp, high flux,
frit like ferro 3110, 3124, 3134, or maybe 3195, on the piece before =
applying
the glaze. Not sure which COE would be better, they range from 7 to 10.
Any thoughts?
Thanks in advance for your replies,

I'm actually about to try this very experiment. I'm switching from low-
fire clays to cone 6 and I have a bunch of random 04/06 glazes left over.
Someone told me that some of them might work fired that high.
So, I've made a couple dozen little shot glasses and I'll put glaze at the
top inside, about an inch wide strip. That way, if it all melts off the
pot, it will just melt into the shot glass and not ruin my kiln shelves.
I can post results with links to pictures when I do this if people would
like me to. It may not be for a couple more weeks though.

Hi Alex,
I too would love to see them, as I used to do low fire some years ago and
have glazes left over.
Thanks in advance.

Hi Donna and all,
A very long time ago I was using low fire glazes as highlights on
cone 10 pots. One of them is still at a friend's house to remind me.
I just don't remember having any problems like this. The commercial
glazes have so much gum in them that they always stuck fine.
If the glaze was shrinking more than the body then wouldn't it crack?
I think the red glaze which needs three thick coats was not thick enough
in places.
One problem with applying brush coats in this manner is that if you aren't
really hard and dry between coats you can actually be taking glaze off
with the brush instead of adding it!
Best,
Eleanora
