I was browsing the Laguna Site for raw materials and clicked on a marquee ad
of theirs for:
*Arroyo Slip*
Laguna is testing out this version as a replacement for Albany Slip.
A 5lb sample, is for $8.95 includes shipping.
[I did not ask if it was dry or wet weight]
and can be had by check or contacting this individual by email

Let me know if any of you have tried it and if you like it or not. JoeC

Joe, I tried arroyo for some ^6 Albany slip glazes and even with glaze
software ( where you will see it is not a 1:1 replacement) I was unable to
get the same glaze look. I think arroyo has some potential but there is
still something not reproducible about Albany for my glazes. I think it is
either some trace elements or fineness of the clay that gives it that
special look.I have tried many subs.
The closest I have come is with some clay in my driveway but it won't
work unless ballmilled overnight.

Never thought the key might be that fineness of the particles for starters.
That glacial silt. And Maybe like you say trace elements that aren't there.
I bet some minerals that might be dissolved just aren't there as those found
in an Albany slip. Sort of like the varying kinds of dissolved minerals found
in mineral waters on the shelves from around the world.
I understand better now, that some of the joys of Albany slip were found in
their inclusions in glaze formulas. I can see how that component would be
tough to formulate (if it was no longer available) and then include in a
glaze formula. Sorry for stating the obvious. Just looking for roots to
thinking. I better understand the frustration people have had over this.
Some have eluded that there was more than free iron in Albany slip. Large
nickel deposits weren't too far from upstream in Canada. I'm also firm
believer that pigmented slip glazes needs some curing time. Maybe part of
the magic came from a biological breakdown. The very nature of clay included
eons of wear and decay in building sediments.
I got a little perk of interest about the clay in your driveway. Sometimes
that's what it takes.
Maybe there are some lessons from the recipe agents who make there own terra
sigillata; ie people who know the characteristics and behaviors found in very
very fine sediment levels in clay. (I think about those gel layers sitting
right below where the water separates from slurry.
Sometimes just like albany slip, amounts of terra sigillata were not ment to
decorate or be added to glazes. The site below shows the "bean pot" usage of
a very fine slip as an odd example.

Thanks.

At Plainsman Clays we have just made the first batch
of Alberta Slip II (the version I will still be available).
It is marvelous, chemistry is closer, and it is much more
silty (less plastic). Makes a great tenmoku all by itself
at cone 10R. Write me at plainsman @ digitalfire.com if
you are interested.
