peacefulacrez:questionableadvice:~ Valuable Receipts, or the Mystery of Wealth; Containing the Lady’s Cook-Book, Together with Several Hundred Very Rare Receipts and Patents to be Found in No Other Work, by J.H. Prescott, M.D., 1845This test is actually where the measurement “alcohol proof” comes from.The term originated in the 16th century, when payments to British sailors included rations of rum. To ensure that the rum had not been watered down, it was “proved” by dousing gunpowder with it and then testing to see if the gunpowder would ignite. If it did not, then the rum contained too much water and was considered to be “under proof”. Gunpowder would not burn in rum that contained less than 57.15% ABV. Therefore, rum that contained this percentage of alcohol was defined to have “100° (one hundred degrees) proof”. The gunpowder test was officially replaced by a specific gravity test in 1816.Reblogged due to interesting information added by peacefulacrez. Who knew that mixing your wine with gunpowder and setting it on fire was actual science?!**Probably everyone but me, actually. -- source link
