I personally use about a tBsp of bicarb per litre of ethanol (not lets
say 30% diluted stuff). Then dilute to a safe level for distillation.
As to safety with copper: alkalies with dissolve copper compounds
(including oxides) to some extent. Copper itself is usually fairly safe
providing you don't supply oxygen to the mix.
Just make sure you wash the boiler very well right after distilling.
