Claw Molding

Finally getting to the molding process of two of the Falcarius claws collected at the Crystal Geyser Quarry.  Reconstructed the missing tip on one and added just a smidgeon at the end of the other to complete it.  Looking good so far.  We’ll see in 24 hours how the molding material set up and get to pouring the other side.  Then on to the casting.

Two claws set up for molding. These specimens have been carefully surrounded by clay along the flat edge of the claw. This is the best spot to have a seem in the two-part mold.
Claws and mixed rubber ready to go. The clay base has been surrounded by a clay wall and sealed. A groove has been created on the flat surface of clay surrounding the claws. If you look closely you will see pointed numbering that will be a permanent marking to identify the specimens.
The mixed rubber in liquid form was first painted on the surface to ensure that no air bubbles will be trapped. The remainder of the rubber was then poured into the mold, with a little bit of giggling to release any additional bubbles. Now the mold will sit for 24 hours (the curing time of the rubber).
