Intricate decorative pieces may have 50 or more "heats" involved
in producing them. The metal doesn't "wear out", though as I noted
there will be some losses to scale formation with each heat.

With my slow going I've probably heated a lot more times than that... and
the surface still spark tests 1080/1090 in carbon content. Not even 1040/60
range anywhere. So there's not really much loss at all.
