Solid air

In 1893, Professor James Dewar communicated to the meeting of the Royal Society that he had succeeded in freezing air into a clear, transparent solid. The precise nature of this solid was not known, and needed further research. It was speculated that it may be “a jelly of solid nitrogen containing liquid oxygen, much as calves'foot jelly contains water diffused in solid gelatine. Or it may be a true ice of liquid air, in which both oxygen and nitrogen exist in the solid form.”At this time, Dewar had not been able to solidify pure oxygen, although nitrogen had been frozen with comparative ease. It also had already been proved that in the evaporation of liquid air, nitrogen boils off first.
