Delft clay casting demonstration

In January 2020, John Huddleston gave a demonstration of how to cast silver using the delft clay method.  The club has the equipment for this.  John used a nutmeg as the item to reproduce and did two castings to allow more people to watch closely.

With the first pour, John didn’t keep the torch on the crucible whilst pouring and the metal did cool a little so that the mould didn’t fill properly.  The second one was fine.  The first one will make a lighter pendant at 33g, whereas the full nut is 44g.
