Oil Bath: a Metal Jacket of Dried Oil with a Thermometer (Morfit, 1849)
A bath of hot oil that heats a flask, dish or retort evenly at temperatures above the boiling point of water. Campbell Morfit (1849) builds it exactly like his water-bath: a metal (or porcelain-lined) vessel holding the oil, with the vessel to be heated set in it, and a thermometer in the oil to read and regulate the heat. He gives up to 570 °F (about 300 °C).
The oil is first heated for several hours in an iron capsule to drive out its moisture. Which oil, and the vessel sizes, are not given.

"The oil should, before its transfer to the bath, be heated in an iron capsule for several hours, to expel moisture. The bath consists of a porcelain lined or metallic jacket, of construction exactly similar to that of the water-bath. It affords a temperature of 570° F., and the facility of determining its temperature, for which purpose a thermometer is a necessary accompaniment."

Heat the oil in an iron capsule for several hours to drive off its moisture. Do not heat it so far that it decomposes. Which oil is not given (unknown). Ours: a shallow metal pan for the iron capsule.

Set up the jacket
Take a metal vessel wide enough that the vessel to be heated sits inside with space at the bottom and sides (Fig. 150: the outer vessel A carries an inner flange a on which the dish B rests). Pour in the dried oil, set the thermometer in the oil, and heat on a charcoal furnace or gas stove. Sizes are not given (unknown). Ours: a metal pot.

Set the flask, dish or retort in the oil and regulate the fire by the thermometer. Oil loses less by evaporation than water and gives temperatures above 100 °C, up to 570 °F (about 300 °C). Boiling oil throws off a very disagreeable vapour; keep the heat below the point where the oil decomposes.
