How to Work With Hard Wax for Lost Wax Casing

I did this at TechShop Menlo Park. http://www.techshop.com
You can use any kind of wax for lost wax casting. Red french was is the easiest to use as its malleable and paraffin is good for carving. I ended up with a giant block of green machining wax. This is one of the many creative ways to deal with the situation:

Step 1: Cut Into Pieces

Using a vertical wood saw, cut into chunks.

Step 2: Line a Crockpot

I used a large crock-pot and lined with aluminum foil to protect it from the sticky wax. 

Step 3: Add Wax and Water

I added one cup of water which sinks to the bottom and doesn't mix with the wax. It just speeds up the process. 

Step 4: Melt the Wax

Turn the crockpot on and adjust to low temperature. In about an hour the wax is melted, soft and workable. 

Step 5: Make a Sculpture

Use oil to cover your hands so wax will stick to you less and line your work area with plastic. 
Time to play!!! :)
