Making Wax for Carving, Casting, and Machining

Pouring, Hand-Forming, Detail-Carving, or Polishing – Wax Does it All

Sculpting and hand carving are skills that do not come naturally to me. I can visualize, create, and generally comprehend geometric forms, but there are some things that I just cannot see while working on shapes in nature, and this includes human faces and figures.

I do still need to be able to create an acceptable figure or head now and then for automaton or animatronic projects, but unless some skill develops it is destined to be a “rework until good enough” endeavor. I can live with that shortcoming as long as the job can still eventually get done. It does however require the selection and use of sculpting or carving materials that can tolerate a lot of mistakes and rework. The ideal material would be easily hand-moldable yet firm enough to hold shape and detail without fear of damage from the slightest mishandling. It must carve easily, but it should also allow easy addition of material to fill in mistakes.

After trying a few different types of sculpting media (water-based and polymer clays, oil based plasticine, basswood, carvable foam) I decided that carving wax was a material that I could live with.… Read the rest

After experimenting around with a few different sculpting mediums, wax seems to be a material that I might be able to do something with. Subtractive sculpting in wood requires too much vision, training, or talent – none of which I have. Clays allow addition of material to fill in mistakes, but I haven’t had much luck obtaining a finish suitable for producing a final mold from which I can cast multiple pieces.

But wax is different. Some of the harder varieties of sculpting wax can be carved and polished to a very high finish and are durable enough to easily make it through the process of mold-making. The ability to build up or repair wax fairly quickly makes it attractive for experienced sculptors as well as those of us that have to repeatedly add or subtract material until whatever we are making looks right.

It took about five minutes of using an alcohol lamp to heat tools and melt wax to realize that an electric wax pencil would be a necessity. And since I didn’t know much about what I needed or whether I would stick with carving, I looked for something that didn’t cost several hundred dollars.… Read the rest
