Alginate can actually be applied straight to the skin – which I think is something we should try as we will get an even more detailed impression of the face. These are some examples I found online:
If we can apply this straight to a face and then use the cast to fill with agar, then this could be great. From looking at these examples, I suspect that this is how the chocolate gelatine head that I spoke about the other day was made. We hope to try this, I’m going to look for a youtube demonstration to hopefully explain the method of this a little better.
