They have renamed this to Ravenscrag Slip and I made a cool
'raven' logo for it. They are now shipping samples.
This is a very unique material, 100% gives you a silky white
at cone 10. Add 20% frit 3134 for a glossy clear at cone 6.
There is a 50 mile long 3 foot thick layer of this stuff at
the quarry site.

The huge advantage of this material is this:
It has great application properties and you can lay it down
in multiple layers on bisque or greenware without crawling
or cracking. This opens a whole new world of possible
decorative effects.

For detailed info visit its webpage at

You can request a sample from this page and it will be
available through the Archie Bray Foundation in the US.
I will be updating this page constantly. Please email me at
plainsman@digitalfire.com after you have tested it and let me
know what worked and what did not so I can post for others.
I want to create a reference for students to foster the
create-and-understand-your-own-glaze movement.

If you need to duplicate Albany slip with this material try
starting with 4-6% iron and about 15-25% frit 3134. Adjust
for color with the iron and increase or decrease the frit to
adjust melt fluidity.
