Sand Casting for Jewellery

Using the ancient silversmithing process of sand casting, you will learn how to produce small scale jewellery and objects with precious metal & take home a personalized, ready-to-wear sterling silver jewellery.

Sand Casting uses a special type of sand that has a clay-like consistency to create a mould into which molten metal is poured. This is a fast and easy way to create your own items from non-precious materials such as metal, wax, wood, or plastic models.
