I definitely don’t want to revive the debate on centrifugal v
vacuum casting but I do want to experiment with casting on a
I have cast with cuttlefish (fun but smelly) and Delft clay
(less smelly and more repeatable but model shape is too limited).
I don’t want to purchase a vacuum table to debubble the
investment but have noted the adverse comments on debubbling
additives – can I not just vibrate the investment and then the
invested flask as I am told it was done ages ago?
Assuming I can get a decent investment then how to cast. Gravity
works for cuttlefish and clay, why not for investment (with or
without steam assist). I can probably improvise centrifugal but
wonder at the need.
My parameters are Sterling Silver only, max flask size probably
3*4, no more than 4 pieces per tree and one or two casts per week
- I did say small scale didn’t I.
I could probably spend a lot of time experimenting but I would
rather cut stone ( this metal thing get’s more fun as I learn
