One of the eight-sided domes being prepared for the mold making process.

3

Parting shims were created from clay and wood to segment the dome. Smooth-On's Super Seal® was used to seal the stone surface and shims.

4

Smooth-On's EZ-Spray® silicone is sprayed in layers over the original

5

The EZ-Spray® Jr. gun is highly maneuverable allowing mold rubber to be applied to undercuts and hard to reach areas.

6

Typically 4 layers are sprayed to an ultimate thickness of 3/8'' (1cm).

7

Smooth-Sil® 930 is thickened with Thi-Vex® thickening agent. Thickened rubber is used to fill deep undercuts to prevent mechanical lock between the support shell and the original model.

8

The process is repeated as sections are completed one at a time.

9

Mold making in progress

10

Once the mold rubber has full cured, support shell segments are created using fiberglass and resin.

11

Shell is built in eight pieces with supports embedded for better structure

12

Once the support shell has fully cured, sections are removed exposing the cured rubber mold.

13

E-Z Spray® silicone is flexible and can be peeled back from the original

14

Silicone has good tear strength.

15

Rubber mold segments are then seated into their respective support shells.
