Hello all,

New here and excited.

i was wondering if anyone knew the correct sizing method for working with ferris wax to carve out rings and then have them lost wax cast?

Do you size just right, size up or size down? and what is the science behind it? I'll be casting mainly in silver for now, and would look to work in gold at some point.

And for a bonus, any favourite casters in London?

Thank you,

T
