Casting molds are CNC machined from USA sourced high purity, fine EDM grade graphite blocks (see graphite specifications in pictures). - Mold is designed to cast one sided round ingot that measures approximately 2 1/8 inch diameter by approximately 1/4 inch thick (size may vary due to amount of pour). - Graphite block dimensions are 2.5" x 2.5" x .5" thick. - It can be used for copper/gold/silver/pewter. - You can get many pours with this mold as long as you take care of the mold (preheat mold before pour, keep out of moisture, don't drop, etc...). - Ingot is not included. This listing is for graphite mold only.
