maybe a VERY stupid question but ill ask

[dtec1]

ok guys so this may be a very stupid question but..... is there any reason that you cannot melt and cast copper like you can with brass??? so I have made my own brass pieces before from scrap lying around for bolsters and such... well I just started working on a new hidden tang and I wanted a nice thick copper guard so I had a bunch of scrap copper. I used the same crucible that I have for brass well no not the same exact one but its from the same thing. problem is the copper didn't seem to melt so I slowly turned the heat up every few mins as I didn't know if too much heat could burn it and ruin so I went slow so eventually exactly what I was trying to prevent happened the metal seemed to burn away and yeh it got soft but not much of it got to real LIQUID. so idk I really did turn the heat very slowly so I wouldn't have this happen and it happened anyway so idk maybe its not even possible to do with copper??
