A: It depends on 1) the type of mold rubber you are using as your mold material and 2) the make up of your concrete ad mixture. 1. What mold rubber are you using? Silicone rubber has the best release properties, but will succumb to the abrasive effects of the highaggregate content of the concrete and lose detail over time.
(18) "Portland Cement Kiln" (Kiln) A system, including any solid, gaseous or liquid fuel combustion equipment, used to calcine and fuse raw materials, including limestone and clay, to produce Portland cement clinker. For the purposes of this Rule, three types of Portland cement kilns are described:
Mold Making for Slumping Mirrors in a Kiln BBAstroDesigns
After failing with a mold made from sand (see below) and listening to David Davis'' advice on the resiliency of refractory molds, I decided to create plaster premold masters precision ground to shape. The plaster premold is used to cast the refractory mold that will be used in the kiln to slump the glass.
