Casting Workshop Weekends at Northern Districts

Our workshops are held over the two days, Saturday and Sunday. Participants need to be able to attend both days from 9am to 3pm. Saturday is devoted to preparing your model, either carved, constructed from wax or use of suitable natural items.

Spirit Lamp

Towards the end of Saturday we invest our flasks and leave to set and dry overnight.

On Sunday the flasks are separated from their base and placed in the kilns where the temperature is gradually increased so the model completely burns out. Hence the name of the process “Lost Wax Casting”.

On Sunday afternoon the flasks are removed from the kiln, the silver is melted and thrown into the void by means of our centrifuge. Tense minutes follow as the spent investment is removed to reveal your creation.


Items required.

  • Small methylated spirit lamp. The finer the wick the better, as heat is more easily controlled.
  • Lecron Dental Tool. This tool (pictured below) is the most necessary tool for working wax. Lecrons are now available quite cheaply in a set of dental type tools available from ‘House of Jewellery’.
