The year 1756 in science and technology involved some significant events.

Chemistry

Joseph Black describes how carbonates become more alkaline when they lose carbon dioxide, whereas the taking-up of carbon dioxide reconverts them.
Mikhail Lomonosov disproves the phlogiston theory of combustion[1] and pioneers the study of oxidation by converting tin to stannic oxide.[2]

History of science

Thomas Birch begins publication of The History of the Royal Society of London.

Technology

John Smeaton produces the first high-quality cement using hydraulic lime since Roman times for construction of the third Eddystone Lighthouse (completed 1759, following burning down of the second in 1755).
The recipe for mayonnaise (originally "salsa mahonesa" or "maonesa") is probably brought back to France by his chef after Louis François Armand du Plessis, duc de Richelieu's military success on Minorca.[3]
