lost wax casting...

So i have been doing some research and i'm thinking that the best way to achieve the outcome that i want is to try the lost wax casting technique.
i have placed an order for some blue carving wax and some carving tools... just waiting for them to arrive so that i can get sampling! Fingers crossed there is the equipment to cast metal at uni.
Here are a few examples of jewellery that has been made using this technique.
