Hi,
I've received more email about Jasper Slip Clay and so thought I'd reply to
the List. I received the information about the product a good two weeks
after receiving the sample. There are four pages of notes and recipes. It
can be used "as 100% of the glaze . . . from cone 4 to cone 12 and higher,"
or as a glaze constituent. Many of the recipes use it as a substitute for
Albany slip.
They include a web site address but last time I looked it was under
construction:
http://www.fullnet.com/corp/unitedclays/
Their address is:
United Clays, Inc.
1405 Industrial Park Drive
P.O. Box 194
Huntingburg, IN 47542-0194
If you don't get your own mailing from them soon, try writing them. If that
doesn't work I'll mail copies of what they sent me.

Could some one please tell me what I can do with Jasper Slip? It's another
buried treasure I found at the community center studio in Tryon. Can't seem
to find anything in the archives. Your helped is greatly appreciated!
My conclusion about Alberta Slip is that it is a substitute but it isn't the
same as Albany Slip. People have said to hang on to it and use it in a
killer glaze. Just where exactly was I going to find one of these killer
glazes. Fortunately, there are CMs from the 70s and 80s at the studio and I
have found many of the old recipes. There was one person on the list that
was kind enough to send me some of the recipes too. Everyone else said "sell
it" or "hang on to it". Bonnie also mentioned that the Jasper Slip may be
something used with volcanic ash....I have lots of Mt. St Helen ash. Does
anyone have ideas on how I can use these?
TIA

Well, you could fire a sample of the slip alone in a normal glaze fire at
whatever temp and atmoshpere you use. After observing the results, you can
do line blends with feldspars and other fluxing agents. Talc, whiting, some
sort of boron or boron frit, wood ash, whatever you want to do. Then
venture on to some triaxials, quads, whatever.
Jasper is an iron bearing slip clay so you'll get some color such as brown,
beige, tan, maybe celedon or darker in reduction. I fired some line blends
and triaxials with wood ash, feldspars, and gerstley borate to cone 6 in
oxidation and got some very nice ash looking tan glazes with the jasper but
that's about all I've done. The next shot is to try it in some shino glazes
in the gas kiln and then I'll try some in the salt.

Carolyn,
I first saw Jasper Slip being distributed in sample quantities at NCECA in
Las Vegas a couple of years ago. Attached are some recipes from the people
who staffed the booth. Hope they help.
