The Mystery of Fathers

"I want to pick your brains about metallurgy"

"Oh, I've forgotten all that stuff"

Twenty minutes later, after a tutorial which included heaviness of osmium, the conductivity of irridium, the percentage purity of sterling silver and 22-carat gold, the oxidisation of copper, the smelting and thieving of lead, the strength and consistency of titanium, and the qualities of platinum when it is heated over a gas ring (it keeps its colour), I had all I needed for a little sermon about how sometimes the noble needs to be mixed with the base in order to do its job.

"Forgotten all that stuff"!
