Big Scale model sitting under a thin layer of silicone 

Grinded down old silicone molds and mixed it with a batch of fresh silicone to save materials. Lot of work though.


Hydrocal gypsum support mold.


Slush cast model using Smooth cast 300.


First pull looks really good still need to smooth things out and restore some elements. When the model is done a new mold will be made.
