Firing Rocks in the Kiln

 

This is part two of a multi-part tip on slumping over rocks in the kiln.  Click here to go to part one.

 

Now that you're certain that the rocks can survive the firing, you're ready for the next step.  You'll need a piece of glass the right size for your project, and enough rocks to form a "river bed" beneath the glass.  The glass needs to be around 1/4" (6mm) or thicker.  Float or plate glass will work (you may need to fuse thinner pieces of glass together to get a piece of the right thickness).

 

Arrange the rocks on the kiln shelf. You want them nestled against each other and covering a smaller area than your glass.  Once the rocks are arrange, coat the top surface of the rocks with kiln wash.  Spraying the wash works best, but it's possible to brush kiln wash on if you're not able to spray.  You want to make certain that the rocks are coated with kiln wash, but there's no need to apply a thick layer of wash.  If you're not sure if you did a good job of coating the rock, you can also dust the top of the rocks lightly by sifting on a thin layer of dry kiln wash powder.

 

Once the rocks are kiln washed and ready to go, it's time for the glass.  Clean it thoroughly (you don't want fingerprints to show), then balance the piece of glass on top of the rocks.  It may rock slightly, but that's not a problem -- the firing will help it settle into place.

 

Coming soon -- the firing!  And what to do after you fire.
