How To Do Basic Gravity Casting:

This sculpture technique is as ancient as mold making itself. It has only two rules:

1. Gravity pulls only straight down. This controls where the liquids can go.

2. Air moves only straight up. This governs what must be done to eliminate bubbles & traps in both mediums

•, Air rises until it hits something (like the inside of a horizontal part of the mold) and sticks.

•, If areas of your mold are not straight up and down, make your first pour only about half full.

•, Tilt, tap & jiggle the mold while rotating it. This will get the casting medium into the angles and push the air out of high areas.

•, Then fill the remainder and repeat. Finish by tapping the matrix all around with your knuckles.

How To Minimize Air Bubbles:

Air Bubbles Come From 3 Sources:

1. Surface Bubbles cling to the skin, (hair shafts, between fingers, etc.) They appear as bumps anywhere on the sculpture. To prevent them wet the skin and move around in the liquid ArtForm™ before it sets.

2. Mold Bubbles are mixed into the ArtForm™. They float up and stick. Appear as bumps on the bottom of the sculpture. Prevent them by moving around in the liquid until it becomes too thick for the bubbles to float through.

3. Cast Bubbles are mixed into the ArtCast™. They float up inside the cement and appear as holes on the top of the sculpture. They are prevented by the correct soaking and blending of the cement as well as by the correct Gravity Cast technique as described immediately above.
