Re: Aluminium cast Clone Trooper Helmet
Hallo mugatu,
I don't really know if there is any other name for it, because normally I just handle with the german terms. I just used to find a correct name by searching for the technique at wikipedia and than switched to the english side, which is this one: http://en.wikipedia.org/wiki/Lost-wax_casting I didn't read it on english yet, but maybe you can find something there. As far as I know, the wax is just called wax and thats what it is of course. Do you want to cast something? In fact, there are many types of wax you can get. the most important thing is, that it can be burned out very well, but for a foundry its also important to have special physical characteristics, such as you can connect it well, it shrinks less or its harder. candle wax is also possible, but its not so good to work with, cause there is a lot of paraphine in it and its hard to sculpt and difficult to connect parts to each other. In the foundry I ve been working, we use one layer to brush it into the negative form, meaning the wax you can see from the outside ( the green or purple one) and one layer which is cast into the negative form and than out, so you get a regular layer thickness. this is the brown/ red one which is also much harder to give the sculpt more stability. the green one is softer so you can retouch it well and it also shrinks less. I hope that helps a little bit, and its what you were asking for.
