If at first you don't succeed, try, try again

I've had a lump of what I'd thought was copper at the back of my bench for years - rescued from the scrap of my foundry when I moved all those years ago, so I thought I'd try and melt that - about 5 kg.
Well it was too large for the crucible on the inverting furnace body so I started cutting it in two on the band saw. I wasn't entirely surprised when the blade broke - copper can be gummy, it was over an inch thick and far from stable on the saw table. Never mind, finish it with the Angry Grinder with a 1 mm disk. Now soft copper and disk cutters don't go well together, so why was it cutting so well

Because it's BRASS

It had only looked coppery as the surface had been de-zincified.
So now it fits in the pot I went through same rigmarole turning everything on, ran it up to 75 KW - took a decent picture this time of the generator panel (!) returned to the foundry and it was already practically melted. Another less than a minute and the zinc was boiling off, time to invert the furnace.
I got a little bit of brass splash as it went over - I was probably a bit too slow doing it - then the furnace driver gave me an error light. (Water pressure or temperature to / from furnace body but not sure which)
Everything turned off, drop crucible released, and a 2.5 kg dome shaped lump of brass was deposited on the floor.
It was at this stage things got a bit hectic as one of the brewers hoses that carry the chilled cables from the driver unit to the furnace body decided to burst and squirt coolant onto the floor.
Now this is not entirely a negative, as it will persuade me to replace them despite the not inconsiderable cost, and it is best for safety anyway.
So this escapade had proved that the furnace is fully working, albeit that I have a few issues to correct.
Quite impressive rate of melting - 2.5 kg of brass in about 5 minutes - actually probably a bit less as I'm taking that timing from time stamps on the photographs.
. . . off now to cost rolls of Brewers Hose
