I have 2 high quality rubber-molds for casting classical Fireplace Surrounds as Pre-Cast items. I have years of experience making new design to the customers specifications with the samples shown. I can make simple molds with a scagliola stone look in just about any size. Anyway - I am sure that I can figure out a solution to any problem with the right look, and have it be the proper fireproof "heat-sink" application. Give me a call.
