I want to use David's suggestion made some time back for adding yellow
inclusion stain to a slip glaze for ^10 Reduction firing. I have what I
think is a reliable slip glaze recipe gleaned from Clayart some time
ago. Anyway, looks to me as if it would work. Problem: I am not sure how
to use a slip glaze. I'm guessing that it's applied as most slips, maybe
in this case even to wet clay, but does one then use a clear glaze on
top or just leave the slip glaze as THE only glaze? And, yes indeed, I
WILL experiment and try different methods to see which I happen to
prefer ... but it's nice to benefit from others' experiences for at
least a starting point. We each have our own learning styles, and that's
mine ... This is my third attempt at yellow. Geoff from Australia sent
me his recipe which I like very much ... but still want to use the
DeGussa stains ... too expensive to just let sit.

In the Mojave luxuriating in cooler weather ... not just early morning
and late evening, which we've had for a week or so, but just about all
day ... 55 F this morning.

Hello Joyce:
Slip glazes are usually, and I emphasize usually, glazes that are made out
of an iron bearing slip clay that will melt into a glaze at the temp one
fires to. Most slip clays such as: barnard, albany, alberta, jasper, will
for sure melt at cone 10 and some are OK at lower temps. Barnard is pretty
refractory and needs additional flux for even cone 10. Albany and alberta
melt into a dark glass at cone 10 R. Alberta, all by itself is a balanced
glaze at cone 10. Anyway, you can also add other minerals and colorants to
slip clays to control melt, texture, color etc. Depending on the clay
content and raw shrinkage rate, they can be applied wet, leather hard, bone
dry, or on bisque. I don't know what receipe you have so I can't advise
you here. The slip glazes that I use at cone 10 R and also in the salt
kiln don't need another glaze applied over the slip glaze. Try both, you
may get 2 very nice glazes. If your slip glaze contains a fair amount of
iron, it may overpower the yellow that you are trying to get. Maybe
Ravenscrag slip would be a good one to try because it is pretty white at
cone 10 R.

Thanks to Mighty Gurus David, Craig M., Johanthon K., Tom B .... with
more info still coming in... my understanding has increased manyfold.
Each one added something that the other hadn't mentioned, such as
testing Ravenscrag as a base since it's supposed to fire white and might
work well with inclusion stains. Oddly enough, I had readied the order
for Archie Bray last week and just hadn't sent it in (need stamps ...
keep forgetting to stop at the post office when I head down our sandy
road into town) ... Looks as if this next firing will have the inclusion
yellow in it ... Hooray for me! This yellow and the artificial salt
glaze, plus my beloved cracked shino and June Perry shino, and ONE pot
glazed with the ugly-acting rutile, will do it for this load ... major
improvement over firing maybe 10 glazes at once. Working on my addiction
to mixing up every glaze I see on Clayart... have to withdraw gradually.
Don't tell Mel and Tony, or they might quit helping me and then where
would I be??? I'm doing one pot with the UA rutile because I've noted
that one pot in ten with this glaze makes it through intact, no running,
looking good. Soooo, I figure I'll only fire ONE and thus perhaps
eliminate the nine bad ones ... yes, I'm blonde ... gray and blonde, but
sometimes the gray's working overtime and sometimes the blonde just
takes over.

In the Mojave wishing we could all be flies-on-the-wall at Vince's
school in Tennessee the next couple of weeks. Can you just feature Mel
and Vince occupying the same space, giving it their usual 145% ... their
students will be reeling&spinning for sure!

Joyce,
Is the artificial salt glaze you are using the cone 5 one from Laguna? I
have that one, and haven't had very good results with it; it seems rough
and overfired even at cone 5 and is VERY runny (ruined a kiln shelf, boy
was I in trouble with my husband).

The artificial salt glaze about which I commented is from Laguna, but
it's the ^10 one. It definitely does not look like salt-FIRED work, but
has a rough, sort of primitive quality of its own that I do like on some
pots. I also like it when used with Cracked shino ... but it's
definitely not for everyone, I'm sure. I also like it with varying
thicknesses on the same pot.

In the Mojave not liking the sonic booms which rattle us now and then.
Too similar to some earthquake noises. AND something brought the
starlings to our lone reasonably large elm tree. They jabber ALL the
time except when I yell at them. Interesting birds but too many of them
for this desert acreage. Even the ravens look askance ....

hi joyce-- I've had a lot of joy using my slip glaze in alot of different
ways.I love using it on my greenware cuz it always 'fits'. But I mainly use
it on bisqued-ware as decoration ( I glaze and fire right over it ) I
especially am happy with the fact that when I put a matte glaze over it
,wherever the slip -glaze is it will go glossy there.Cool effect! I color it
, use it as a slip/glaze decoration ,then wax over that and put on another
contrasting glaze. OOOhhh I've had so much fun!! I do add cmc to make it
easier to brush on , and I don't measure the colorants but I've not had any
ugly colors come out .It has a tendency to go on clumpy ,but it levels
itself out. Be not afraid!! I don't know what slip-glaze you are using but
mine should be on the archives. Best of Luck---- pamalab

Hi Pamela,
I searched the archives and found some postings of yours, but no
recipe for you slip glaze. If it fires at various temperatures, including
cone 6, would you mind posting it again.
Thanks in advance and Happy New Year.
All the best.
