Well… As it has been pointed out to me plaster can’t seem to cop the heat needed to be casting more than about 20 tokens. I’m sure that the size of the tokens and the size of the button required to supply the pressure needed also didn’t help. Due to the time issues I am left with only 2 choices…
- Forget the experimentation and carve a back for the mould out of soapstone, basically going with an option that is known to work
- Try again with a different medium and hope that the experiment will produce at least 25 usable tokens. If I did go with this option I would consider using clay as the main alternative medium as I believe it would hold together better.
Another option is to get some hard wax for lost wax casting and use the current mould to make wax tokens that I then add to a huge wax tree and cast 30-40 tokens in one go. I’m tempted to ask for help from a friend on this one, as I need to have the tokens made by Monday and I’m daunted by the task of having to hand carve the text. Though the idea of doing lost wax casting is also interesting.
