I had not heard of this product until I needed to repair some ceramic ornaments. I was looking for a self setting clay that didn't need to be fired in a kiln. Its simple to use and once set (24 hours) it can be filed, drilled, painted etc. Its basically an epoxy putty. I have dozens of uses for it around the house. Just go to the Milliput web site to see what amazing uses it can be put to.
