I have a few more questions would youi know where i copuld find a book or a video, which will give step by step instructions on how to make a mold, i have visited the smooth on site they have a lot of info there .... more info is better right....

I really do not know which type of mold material to use should i be using polyurethene rubber , silicone, or polysulfide ..

I would like to cast the sculpture in bronze possibly resins and then maybe concrete is there a mold that is this versatile or do i have to choose the preferred casting medium bronze or resin first then decide which molding material i am leaning towards using the silicone

My sculpture/horse is made of chavant

Thanks Fritchie

I recommend a book called From Clay to Bronze, a Studio Guide, by Tuck Langland. It's pretty basic, but discusses the pros and cons of various methods, and has very good photos and illustrations.

jwebb is right about the Tuck Langland book. It has been very popular and probably still is available for purchase. Many university or public libraries also might have a copy.

On the other issues, don’t even think about polysulfide. That’s a very old, cumbersome (and stinky!) method, and I doubt materials still are available. I would suggest polyurethane resin for your first mold. It’s easy to use, and can be used for bronze (actually wax), most resins and also concrete.

In bronze casting, you make a wax cast with the mold, change this in any way necessary, and make a new mold from the wax, which is destroyed in the cast. You can get about as many waxes as you want from the original mold, though.
