Step #4 Apply splash coat

"Splash Coat" acts as mold release

Face the clay positive with a thin creamy layer of plaster called a "Splash Coat". Pour a steady thin stream, approximately 1/16" to 1/8" thick, trying to flood it on evenly and not trap air. This coat provides a nice release surface and is soft so it pulls away easily from the glass keeping the fine details of the cast.
