The ruling on mixing some Gold with other Gold in the Factory when melting it
Question :
What is the ruling concerning someone who gives his gold factory so that they can fashion it for him, and it is likely that his gold got mixed with other gold when melting the gold in the factory? However, when he receives it from the factory, he receives the same weight that he gave.
Answer:
It is obligatory upon the factory to not mix the possession of the people together and to distinguish each one separately since the quality of gold differs. However, if the quality of the gold is not different, there is no problem with this (mixing) as it does not harm.
Question :
Is it mandatory to pay a fee for manufacturing when receiving gold (i.e., from manufacturers) or should we consider it a running account (i.e., to be paid later)?
Answer:
It is not mandatory that this be paid, because this is a fee for work (and not the gold itself). So, if it is given when the gold is received that is fine, and if not, whenever it is given is correct.
