I have accumulated a couple of buckets of stick on wheel weights that I have culled from the clip on weights. Not having a use for them, I have just let them pile up. Decided I should smelt them into ingots. As I assume they are softer than the clip on weights, I thought they would melt at a lower temp, but unless my electric heating source has gone bad since I last used it, they require a higher temp. Does that make sense?
Thanks for you thoughts,
