Cold Working Glass with Slurry

Cold working is the tedious art of cleaning up your glass artwork for the final presentation.  There are a number of ways to do this, most of them involving machines, diamond bits, tools and pads.

The old-school method is using a water drip with various grits and abrasives to grind the surface of the glass smooth.

Pro’s:  Fairly inexpensive.  I picked up a 24″ wheel for a couple hundred dollars on Craigslist.  The grits are inexpensive as well.

Con’s:  It’s messy and really easy to break the edges of the work you are polishing on the wheel.

Here’s a picture of the wheel:

The grit is place in the hopper and water is dripped over it onto the wheel.  The resulting mix is called a slurry and acts as both lubricant and abrasive between the steel and the glass. Here’s a short video showing it in action:
