For firing cracks in the feet or other parts that may be because the =
piece is not moving in during firing, put silica sand on the shelves.=20
Also I've found a great new patch, the recipe came from Ellen Shankin. =
I've been using it for 5 years or so and it really is a miricle cure for =
small cracks like that. You can use it on greenware, bisque, or high =
fired work. Here it is:
1/3 vinegar
1/3 slip from your clay
1/3 cairo syrup
These don't have to be exact, just dump the stuff in and mix it up.=20
