Introduction: 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!!! :)
