foundry at the top of the yard where we pour the keels.’
‘ Ja, ’ he said heavily. ‘You can melt lead on a kitchen stove. But gold melts at over a thousand centigrade and we’ll need more than a kitchen stove for that. I know; melting gold is my job. Up at the smelting plant we’ve got bloody big furnaces.’
I said quickly, ‘I’ve thought of that one, too. Come up to the workshop—I’ll show you something else you’ve never seen before.’
In the workshop I opened a cupboard and said, ‘This gadget is brand new—just been invented.’ I hauled out the contraption and put it on the bench. Coertze looked at it uncomprehendingly.
There wasn’t much to see; just a metal box, eighteen inches by fifteen inches by nine inches, on the top of which was an asbestos mat and a Heath Robinson arrangement of clamps.
I said, ‘You’ve heard of instant coffee—this is instant heat.’ I began to get the machine ready for operation. ‘It needs cooling water at at least five pounds an inch pressure—that we get from an ordinary tap. It works on ordinary electric current, too, so you can set it up anywhere.’
I took the heart of the machine from a drawer. Again, it wasn’t much to look at; just a piece of black cloth, three inches by four. I said, ‘Some joker in the States discoveredhow to spin and weave threads of pure graphite, and someone else discovered this application.’
I lifted the handle on top of the machine, inserted the graphite mat, and clamped it tight. Then I took a bit of metal and gave it to Coertze.
He turned it in his fingers and said, ‘What is it?’
‘Just a piece of ordinary mild steel. But if this gadget can melt steel, it can melt gold. Right?’
He nodded and looked at the machine dubiously—it wasn’t very impressive.
I took the steel from his fingers and dropped it on to the graphite mat, then I gave Walker and Coertze a pair of welders’ goggles each. ‘Better put these on: it gets a bit bright.’
We donned the goggles and I switched on the machine. It was a spectacular display. The graphite mat flashed instantly to a white heat and the piece of steel glowed red, then yellow and finally white. It seemed to slump like a bit of melting wax and in less than fifteen seconds it had melted into a little pool. All this to the accompaniment of a violent shower of sparks as the metal reacted with the air.
I switched off the machine and removed my goggles. ‘We won’t have all these fireworks when we melt gold; it doesn’t oxidize as easily as iron.’
Coertze was staring at the machine. ‘How does it do that?’
‘Something like a carbon arc,’ I said. ‘You can get temperatures up to five thousand degrees centigrade. It’s only intended to be a laboratory instrument, but I reckon we can melt two pounds of gold at a time. With three of these gadgets and a hell of a lot of spare mats we should be able to work pretty fast.’
He said doubtfully, ‘If we can only pour a couple of pounds at a time, the keel is going to be so full of cracksand flaws that I’m not sure it won’t break under its own weight.’
‘I’ve thought of that one, too,’ I said calmly. ‘Have you ever watched anyone pour reinforced concrete?’
He frowned and then caught on, snapping his fingers.
‘We make the mould and put a mesh of wires inside,’ I said. ‘That’ll hold it together.’
I showed him a model I had made, using fuse wire and candle wax, which he examined carefully. ‘You’ve done a hell of a lot of thinking about this,’ he said at last.
‘Somebody has to,’ I said. ‘Or that gold will stay where it is for another fourteen years.’
He didn’t like that because it made him appear stupid; but there wasn’t anything he could do about it. He started to say something and bit it short, his face flushing red. Then he took a deep breath and said, ‘All right, you’ve convinced me. I’m in.’
Then I took a deep breath—of relief.
