Topic Subject : Childs bottom cast. |
|
Hi there. I am based in the UK and I have made a cast of a small childs bottom, with written consent of the parent to make into a piece of artwork for them.
The parents want the plaster cast used to make a coldcure bronze piece, with two holes to hang it from. I could use eyelets instead I guess on the back, they want to thread some ribbon through it to hang the piece. I am not sure how I add holes for hanging the piece, if it is best to drill them out once the metal has cured, or add some clay uprights to the plaster cast before making the second mould, which would then leave holes in that second mould. The metal would then have to have something stopping it from gushing out of those holes when I pour the piece though.
I am use to working with coldcure metal, but have never created a piece quite as open as this, I usually work with hands and feet. I don't quite know how to pour the metal so that it is thick enough to be strong, but not too heavy and even in thickness all over.
The plaster cast I made was strengthened with hessian between the layers, I think it is called scrum? I was wondering if I should do that with the coldcure piece, or if it is better to pour all the metal in one go. I am not sure that will work unless I have a very strong outer shell to my mould as the weight of the metal might distort the cast.
If anyone can offer me a few tips before I start that would be really great.
Regards Helen
