Yes it was. But I don't understand what form the hot silicon liquid that would be poured into a crucible  take when it cools down? Does it cool into a solid or does it turn into a powder. Is it the 4N at that point when the liquid cools down or just a solid blob of silicon metal. That is why I asked will it be poured in moulds to create bricks or to pellets etc. I just don't understand what form it takes once cooled from a hot liquid.
