We do have some general tools for working with wax including dental picks, wax files and rasps, some bits suitable to use on the Foredom tool, and wax pens. Wax is very good for shaping and mistakes can be repaired by ‘welding’ new wax in and shaping it as required. One thing I mention to students is that melting and remelting wax several times sometimes makes it harder to work, so be careful about doing this too much.
We do have several pieces of jeweler’s wax in boxes in the tool bench. If you use some please make a donation to Jewelry/Small Metals to cover replacing the wax as a consumable.
There is a jewelry general tools class, but it isn’t required to use hand tools or the wax working equipment. I believe you need to go to the class to use the Foredom.
I usually clean wax prior to casting by blowing it with compressed air or using a soft brush. A brush isn’t ideal, as wax is a non-conductor and will build static electricity, then dust or wax particles will adhere to it and be hard to dislodge. You can also rinse it with water, but dry it thoroughly (air dry) before getting it ready to cast, only because small droplets of water might interfere with the surface or cause the investment to have bubbles in it.
