Resoldering for Enamel

I recently saw an interesting old copper piece that I thought might
be fun to enamel but it was soldered together. I don’t know what
solder was used. I am assuming it was less then IT.

Is it feasible to take this thing apart sand it and resolder it w/
IT? Are there any tricks to this or anything special I need to keep
an eye out for?

Thanks,
Joel
