Gold casted very thinly
When goldsmiths have to solder something quickly but don’t have enough time to forge it, they melt gold and then they pour it on a cloth or on anything else that withstands fire. Then they flatten it swiftly with a hammer or another similar tool, and it [the gold] is very tenuous and it even retains the impression of the cloth.
Unalloyed pure gold can be cast into a medal but not into herbs and lizards or other very delicate things if it is not alloyed.
A pansy which is oiled with wheat oil can be cast with alloyed gold.
And other fruit leaves, but with branch[es] that are not large and especially the leaves, once cast, can be soldered.
