Since I decided to mold and cast my female turian mask using resin, rather than using latex like I did with Garrus, I wanted to do a quick write-up to show some of the differences.
Casting with latex (a soft material) is done with a hard, porous mold, usually made from plaster of some kind. Casting resin (a hard material) requires a soft, non-porous mold, in this case made from silicone.
Meet specimen #1324-AT! This little fellow is a fossilized drakeling, or miniature dragon, captured in time and forever preserved in stone. To be more precise, he’s a cast resin replica of an original sculpture I did.
In the last blog post, Molding and Casting Garrus’ face, I showed you how I made the mold and cast the top part of my Garrus mask in latex. This one will cover some additional mask pieces. I won’t go into quite as much detail about the molding and casting process, since I covered it pretty thoroughly before. I’ll also show how the top part of the mask attaches to the bottom, and get to the beginnings of the neck build.
In the previous post, Sculpting Garrus’ Face, I showed how I sculpted Garrus’ face. This blog will show how the sculpture went from clay to latex, and the continuing process of building the mask.
I decided to make a one-piece mold for the face. Before starting to make the mold, I needed a base to catch the plaster runoff. I started by building a wall of cardboard pieces around the base of the sculpture, attached with hot glue.
In my last post, Garrus – Planning and Concept Sketches, I showed my concept for building the mask – the front/top head piece was going to be separate from the lower jaw, neck, and mandibles. This post will show how I started to build the support structure for the mask, as well as the sculpting process for the top of the head.
Clays made with a base of oil or wax (or a combination of both) are a type of sculpting medium that will never cure or harden completely. This makes them ideal for sculpting a large project that you may need to work on over a period of days or weeks. When the sculpture is complete, you make a mold from it, and then cast it to get your final piece.
