okay... first of if this is in the wrong place, i apologise in advance. so, i have a fair bit of copper, and some gold, and i was wondering if there was anyone here who knows how to make molds? like the kind where you make the mold, then pour the metal in, to make a figurine or some such? how would i do that? also, my clippers (handheld wirecutters) broke, and one of the teeth came of. what temperature do these need in order to melt?

the above questions are genuine, as i know precious little on the topic, but am eager to learn.
