How it's Made - Cast Metal Charms for Jewelry Making

Today we will be working with Lulu and her Husband Alberto. Lulu is our expert in wax casting, and has been part of the team for 12 years. Lulu's family has seen many benefits from working with us at SupplyDiva. She is able to bring her son with her to work, and her husband recently joined our team. This keeps their family together for more hours of the day, which makes everyone happy!

To begin our wax casting project we fill one of our silicone molds with hot wax. Each piece must be cleaned up and inspected for excess wax.

Each wax shape is then attached to a tree which is called a sprue.
A tree of wax figures
The tree must be covered by a metal flask, the holes will be sealed so that it can be filled with plaster (investment).
A flask is placed over the wax tree
The next step is mixing the plaster and pouring it into the flask. Once hardened the wax can be burnt out, leaving the shape of the tree. The flask with the plaster is cooked for approx. 6 hours before we can cast it with metal.

Because it is a long process we usually try to cast many trees all in the same day.
Flasks ready to be cast
We remove the tape that we used to block the holes on the flask before putting it in the kiln to remove the wax and cook them to get them ready to cast.

The final result is beautiful detailed metal charms!
