I went to their Aluminum Foil Saggar and Raku firing
this past Saturday.
Their instruction and set up is quite smooth that even
the student with almost no clay experience turned out some
beautiful pieces.
As we were standing there noting (and stomping out) the flames and sparks
flying
I asked the B&B owner "How do you get permission to do this?
One of her answers was "Oh my husband was a fireman!".
So there we were a bunch of clay addicted pyromaniacs
happy as clams and everyone went home with beautiful pieces.
Paul & Lynne make it look very easy.... he made easy for us too.
If you get a chance to take one of their workshops DO!
My only problem was the terra sig on several of my pieces pulled off
in spots after bisque firing. I used ^5 B-Mix and a local supplier's OM4
terra sig.
I should have made Vince's Terra sig. but had decided to go to the workshop
last minute. Paul uses Vince's recipe and has never had that problem.
When I do workshops I don't expect to come away with magnificent pieces
as I push the limits trying to break out my "safety zone".
Thanks Lynne and Paul!
Hey... next year what about a 55 gal drum kiln making workshop?

Bonnie,
The terra sig popped off after ^06 bisque firing.
The one piece with a too thick application
(dipping instead of brushing) popped off after the
glaze firing.
I'm not claiming it was not my fault... just stating what happened.
I did multiple brush coats (5) waited until the shine was gone
before the next application.
The areas where it happened were on the belly where the piece
flared out the farthest. Maybe brush overlaps there?
I just don't know!

Bonnie and all,
We tell everyone in our workshops that we have used salt in the past, with beautiful effects for saggars, but have had that same experience with it continuing to work on the surface over time. Since we don't wash our pieces after firing, all those chemicals stay on the surface. We suggest not using salt it at all. Some other chemicals give good results instead and are pretty similar to the salt effects.
Gayle even had the terra sig flake off on the inside of a sweet looking little bowl. I was reminded of all the "lectures" on Clayart about making your glaze fit whatever clay body you are using. This is also true of terra sig, slips, and engobes. Gayle and some others bought what they thought was a good product and it just didn't work for their clay body. One of the students applied her terra sig to some bone dry slipware and it had a crackled surface after bisque firing that I said may begin to chip off, in time. It did great in the aluminum foil saggars, got great colors.
Since Paul and I use so much terra sig, we are able to maintain our own supply and have control over the product. That way we also coming off looking good at our workshops, you know, the teacher's work always does come out the best.
