New Work on Tin Plating from Ammonium Stannous Oxalate
Transactions of The Electrochemical Society, 1942 It was found that glue, after hydrolysis by boiling a water solution of same, was as good an addition agent as peptone in the ammonium stannous oxalate bath. The deterioration of the bath was found to be due to oxidation of stannous to stannic ions. The bath can be regenerated by adding some spongy or finely divided metallic tin and boiling.
