Kellie,
If you fire a granite tile it will crumble after firing as the
quartz in it goes through a crystal transition at high temperature .
When it cools it is worthless as a tile. Good glaze ingredient though.
If you fire a marble tile it will be converted to quicklime and be lost.

Does anyone know, if and when a piece of granite tile will melt?? I have
many ideas for glazing and wonder if it is a lost cause to try.

Kellie, don't know how well a piece of granite will fire, but I
would do it very slowly and carefully. It may be best to limit your
first test drive to a small piece. According to the folks at the site
that I'm following this sentence with the melting point of granite is
approximately 3100 F......http://www.graniterock.com/msds_granitesand.html
Hope this helps

I did it!
Here is the before and after Cone06 pieces of the Black Granite tile. I
dripped a few drops of Duncan Concepts yellow, to see if the glaze would
react. It looks GREAT. I love the deep cinnimon sparkles that showed up.
Next I will take it to Cone6. Wait and seeeeee!

New Hampshire granite is mostly feldspar and silica, and I have used it
embedded in the clay for a texture variation. At Cone 10 it will melt
enough to form a soft edged white dot in the surface of the
clay...powdwered and mixed with woodash and clay it makes a nice glaze.

The melting point of granite is 550 degrees C.
