Ultra Smooth Dams (Sets of 2)

A set of very smooth dams is essential for minimizing cold work when firing thick glass.   Our ultra-smooth dams are cut from polished ceramic - and will provide an excellent "edge" on your work.  These are the same smooth ceramic dams sold as part of our dam half-sets, but without the 2nd layer of rough brick included. Ultra-smooth dams sit 1.25" tall and come in 6 different lengths (from 7" to 18") to accommodate the best fit for your project - and the size of your kiln shelf.  They are thin - just 1/4" deep - and so are easy and economical to ship.  For thick glass, they need a 2nd layer of larger, heavier rough firebrick dams for weight control and heat insulation.  (If you are in need of both types of dams, order our kiln dam half sets in the same 6 sizes.) Ultra-smooth dams are sold in pairs, so buy two sets for a complete project, to surround a square or rectangular project.  Ultra Smooth Dams - Benefits & Suggestions: Provides the best outcomes for your multi-laye
