[QUOTE="user 4386, post: 652131, member: 4386"] The smelting process creates not only fancy crystal forms like needles but also minerals that are not known to occur naturally. Here are two examples (I don't think either are what you have). Smelter products often form fine needles - this is caste iron [ATTACH type="full" width="386px" alt="1662106793604.png"]4120[/ATTACH] this is lead smelter slag (needles are calcium phosphate) [ATTACH type="full" width="383px" alt="1662106867773.png"]4121[/ATTACH] The needles in smelter products usually result from it being suddenly quenched to soild from a liquid state, so it does not have time to crystallize properly.
