Sometimes it feels good to use a hammer.  Even if it is glass when it has a purpose and I don’t mean frustration.

A customer favorite plate involves using a hammer to break the glass.  I cut the background piece to the right size for the mold and then cut the inside piece 3/4” to 1” less.

To hammer the piece, it works best when the glass you want to break is on a hard surface like a piece of plywood.  Lay on top of the glass a piece of thick paper like the paper used to wrap glass.  Grab a hammer and a center punch.  It can be a pointy one or not so pointy.  If you want to try to crack the glass right in the center, then you need to align the center punch with exactly where you want it to crack.  Take a good whack with the hammer and it should crack. (Oh, I should have warned you to make sure you have your safety glasses on.)

Remove the paper and check out your pieces.  The good and bad of this process is you don’t always get it to crack as you wanted, but I have found almost all cracks interesting.  See the two different pieces for which I basically did the same thing but got different results.  

Carefully move the pieces onto a piece of cardboard to transport to your workbench.

I sometimes grind the edges just to remove sharp little shards.   Then clean each piece, lay on the base layer of glass and if you want you can glue each piece down.  I use Bullseye Glastac, but you can also use Elmer’s glue.  In my kiln, I fuse the piece to 1380 degrees F because I want the edges to round, but I don’t want the pieces to fully fuse and instead have a nice contour.

Give it a try and enjoy.
