Materials Used:

1. Bottle

2. Balloon

3. Jesmonite AC100

4. Empty pigment bottle

5. Clamp

6. Blade

 

Step-by-Step Process:

1. Preparing the Mold:

We took a bottle and cut it into half, then attached a balloon at the mouth of the bottle.

2. Pouring the Jesmonite:

We poured Jesmonite into the bottle, which then flowed into the balloon. We tied a knot on the balloon.

3. Creating the Depression:

We placed an empty pigment bottle over the balloon to make a depression and used a clamp to hold it in place. After half an hour, we removed the clamp and burst open the balloon with a blade.

4. Final Adjustments:

We noticed that the bottom of the depression had a very thin layer of Jesmonite which broke open, so we filled more Jesmonite in the depression to create a sturdy bottom. We also poured Jesmonite into the small bubbles on the outer section.
