Wax molding hints wanted

Unread postAuthor: boyntonstu » Mon Oct 05, 2009 4:35 pm

I would like to place a glass marble into a wax mold to fit the barrel.

Are there some time and labor saving methods that you have discovered?

Mold release?

Wax melting and pouring hints, etc.?

I would like them to look like these molded by hyldgaard:

Mold rubber? Tap Plastics - How to make a mold box

US Composites sells a few kinds (link)

First make a master copy, gluing it to an acrylic base like in the video. Then using a paper cup to make the barrier around the pattern.

Or making something like this?(waxmold.JPG) Noticed the marble is resting on a taper as to center it, then the wax encapsulates the ball during the pour. You could machine that taper in the bottom or simply hand form a piece of clay to fit into your barrel mold.

Also mold release will probably have to be used. I know you can get by without it sometimes.
