For a variety of reasons that is exactly correct. In general, dental labs
only use new alloy. They send all used metal to a smelting/recycling facility.
Once a year or so, they even roll up their old carpets and send them out for
smelting (like the golden fleece). Even the dust from their vacuums may get the
royal treatment.

I wouldn't use it either if I was a dental lab or a jeweler. Not worth
the cost of failure. As long as his pattern is easily reproducible I'd
give it a try. I do like the idea of mounting the unaltered dental
bits though.
