1/2" Duraboard - per sq ft

Use to make custom drop out molds for unique bowls. You can use the board "as is" or treat it with mold hardener so it can be used for multiple firings <br> The first time you fire the board the binders will burn off  at around 600 degrees and smells pretty bad.  Be wary, once the board is fired it becomes very brittle and if you have not used mold hardener should be handled with extreme care.  Pair with fire bricks to make custom dam molds for frit casting.
