Norm,

I think it needs to be applied pretty thin.  I think the Alberta Slip you have would look more similar if very thin.  I have a terrible time with glaze thickness.  I have a couple that need to be thick and some very thin.  I always have to do a couple of test firings with new glazes to find how it is suppose to go on.

Jeff,

No, I didn't have any problems with cracking or peeling.  Went on very nicely.  I also calcined part of the Alberta Slip.  I just put it in a big bowl in the bisque fire.  I calcine part of my EPK for my kiln wash.  I have bowls I use that were chipped in bisque and never glazed.  I have refired them about six times now.

Make sure and post some pics when its done.  I'm going to try layering a couple of Ravenscrag recipes, but I'll have to wait until I fix my kiln. Got the relays replaced, but now I kilned one of the elements, but thats a whole nuther story!  jhp

Jeff,
I calcined part of the Alberta Slip. It went on wonderfully. I got it to thick on the test tiles and it still looked good. Mixing up big batches today.

Chantay,

    Did you have any problems with the dry glaze cracking or peeling or crawling in the firing? I remember seeing the recipes saying to calcine half of the slip.  I didn't want to do that so I either used Ravenscrag 100%(you don't have to calcine it) or I would mix the Alberta & Ravenscrag 50/50 in the recipe. They always came out nice. I have also used Ohio slip which they say is very close to Albany slip.  It worked really well also.  jhp

I think we're going to buy some Alberta Slip on our next order. That's nice looking - a lot more interesting than this electrical pole insulator brown that our vintage bag of Albany Slip creates - shown here at cone 6 with the addition of 20% lithium carbonate.

It has the same yellow crystallization we get with Vee's Tenmoku Gold using the Digitalfire formula to make our own replacement Cornwall Stone.
