I turned this bowl from the wood of a big garden oak tree that fell in a gale. Oak contains a lot of tannin, which turns black in contact with iron. Writing ink was made by extracting the tannin and adding iron salts. When a nail is hammered into an oak tree the resulting colouration stains the wood, causing woodturners to pay attention. It’s better to detect the presence of nails this way than to find them with the cutting tools!

When I had finished making this bowl I immersed it in a dilute solution of iron for a few hours. This is the result. The harmless colour is inside the wood, and permanent.
