Only the English could invent 'proof' in 1762, which was the technical standard
by which strength was measured until 1st January, l980. If gunpowder and
alcohol were mixed and the spirit was weaker than proof strength (57% ABV),
there was just a damp fizzle. However, when whisky and gunpowder were mixed and
there was enough alcohol in the mixture to cause ignition, then the gunpowder
flashed, providing the 'proof' of stronger alcohol.
To compare: Gay Lussac's ABV to UK and US Proof:
100% (Pure alcohol) = 175 UK Proof = 200 US proof
50% = 87.5 UK Proof = 100 US proof
46% = 80.5 UK Proof = 92 US prof
For UK proof multiply ABV by 1.75, for US double it
