In Topic: Using Propane Torch For Glazing

23 February 2014 - 08:39 PM

Another problem with using a propane torch to fire something is uneven heating. The spots where the torch hits can get very hot, but other parts of the piece are considerably cooler.  The thermo-shock between the hot and cool spots are very likely to lead to cracking as the clay goes through major changes when the chemically bound water in the clay body is released and when the quartz in the ware changes composition when heated.

If you are using the torch to heat a chamber with the ware inside (like a small kiln) so that the atmosphere and bricks are heated as well,  that is an entirely different situation and may work. 

As always, your situation may vary. Test, test, test.

You could try putting some thick white slip through a cake decorating tube fitted with a special tip to get that gingerbread icing look.

(As a disclaimer, I have not tried this, but I think it would work.)

When I did some volunteer work reconstructing pottery from archaeological excavations, we used sand trays to set the bottom piece at whatever angle was necessary and glued the next piece above it so that gravity helped hold it in place. Later when it was dry, we would turn it in another direction and add another piece, again held in place with gravity until the glue set. We used white glue (like elmers) because it was not meant to ever be exposed to water, but I think this method would work with any type of glue.
