Chunk, Sodium Bicarbonate NaHCO3 is what I use -the stuff you
put into food such as bread to make it rise!(Baking Powder I
believe), not the washing stuff, although I would imagine sodium
carbonate Na2CO3 would produce similar results. Laurence Veska.
No not baking powder. That’s also for rising cakes and things,
but is a mix of baking soda (Sodium Bicarbonate) and tartaric
acid crystals, and something like aluminium powder! The acid and
the soda do the frothing, I suppose.
Sodium Bicarbonate is called baking soda, and is used in baking
to rise things that already have an acidic component in them,
