Lead + acetic acid = lead acetate This is attacked by the carbon di-oxide and water vapour, yielding… … After about three months the stack is pulled to pieces, and the lead carbonate scraped off and crushed. This serves to flatten out any unattacked lead, which is sent back to the melt¬ ing-pot. The carbonate is well washed to remove any traces of lead acetate, and after grinding and drying is ready…
