The video below was made in 2004 at our foundry located in Amsterdam. It shows how a "Last Supper" set is made. Like any other product made by our company, everything is made by hand. You see Ingrid van Delden and her father working.
Making a "Last Supper" set takes 2 full working day's for 2 craftsman. It is a very labor-intensive process.
We have made an animated film in which you can see how to make a heat resistant mould, using 2 component silicones (available from our webshop).
This silicone can be used at a temperature of 300 degrees Celsius continuously and 400 degrees Celsius for a short period of time.
This makes it extremely suitable for casting tin. The text is in Dutch, when you are interested in the process and materials feel free to contact us. We are glad to get you started casting pewter with these tipe of moulds.
