Hello there,
a page that is interesting but a good description on the exact composition itself to make a crucible that could be suitable for a bronze casting is hard to find.
How they did that in earlier days when we could not go to the store to buy a crucible.
Here is also a link to make crucibles
but would have preferred a better composition formulle.
If someone has a composition that works that would always be welcome.
