Resin Casting: Rotational Casting

In this video we cast a hollow Frankenstein bust using EZ Flo 120 casting resin. EZ Flo 120 is formulated to thicken as it sets, resulting in a “syrup” consistency that sticks to the walls of the mold. This is an ideal casting resin for lightweight, hollow resin pieces.
