Too much tin, and the copper atoms can't move at all.When the bronze has reached the proper temperature, 2,200 degrees Fahrenheit, it's time to pour.If the metal is allowed to cool, flaws could develop, ruining the bell.
Using cyanide to react with the gold allows them to gradually reduce 40,000-gallon tanks of pulverized sludge to this: three trays full of mud?
This is the first time an outsider has been allowed to pour gold.
A blow causes the atoms to vibrate, but the tin prevents them from moving too far out of position.
Tin is good for a bell, but only in the right proportion.
Out of every hundred bells they pour, 20 or 30 will fail.
