I am currently experimenting with Amaco Potter's Choice glazes. I applied them to my no. 25 white clay, which was bisque.
I applied the glazes fairly heavily and fired to Cone 6. They came out rather muddy with some of the brushstrokes showing. Used Blue Rutile, using a few thick coats.
See pic below.
Are these glazes better suited for stoneware?
If I'm using regular bisqueware for the Potter's Choice glazes, should I try to fire to cone 7-8?
Thanks for suggestions in advance.
My pieces turned out similar. I first did a coat using long strokes. They said for salt buff to apply thin. My second coat was done using a sponging technique and the glaze slightly watered down.
Given that I now consider my platter work using Potter's Choice glazes experimental pieces, what I did was when they were still warm enough to accept new glaze (i.e., right out of the kiln), I applied another coat but this time heavier. I did it with brush strokes in select areas. I figure what the heck, it can't hurt. As for firing up, I am not sure.
I have always been told with refires to fire down. Someone else may have a different knowledge or an opinion. I am not sure. I just know for me, I am putting a hold on these pieces and waiting till I have a big kiln load of refires and doing a slightly lower fired glaze fire with the heavier application. Sometimes you just never know!!
