I was looking into having some things cast in silver. So far I have gotten a general estimate of 2$ per dwt , if 1 oz = 20 dwt then that charge is more than twice the cost per ounce of silver. Of course I might expert it to be more as its probably a formulated casting grain. For rings this cost is not really a big factor but I was looking at some heavier cuffs that may be in the multi ounce weight category so at 40 dollars an once charge from the caster will elevate the prices of the pieces considerably.
How much do caster usually charge for metal above the current spot price?
