Tempi offers a type of engraving which is actually a carving in the wax up prior to casting.
Depending on the size of the piece, lettering can be carved [ typically on the back] which is very readable.
Examples are pictured here.
A flat rate of $6 for/ up to 6 letters. 50 cents per letter after that.
