Important: Safety Warning
This page describes practices involving highly flammable materials in ways that create a serious risk of fire or explosion.
In addition, this page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.

To Obtain Heavy Carburetted drogen
The pure gas may be evolved by Hydrogen. Heavy carburetted hydrogen is gently heating hydrated phosphorus acid in a prepared by heating in a retort 1 part of alco- small retort, and collecting it by a pneumatic hol with 6 or 7 of oil of vitriol until it black-trough. (See No 4031.) ens, and conducting the mixed gases through The spontaneously inflammable variety of milk of lime, which retains the sulphurous this gas is made by boiling phosphorus with acid; and afterwards through oil of vitriol, solution of potash in a small retort, the beak which absorbs water, ether, and alcohol. This of which is kept under water: as each bubble may also be prepared by passing the vapor of gas rises from the water, it inflames, and of boiling alcohol through a mixture of 10 forms a ring of white smoke, which dilates as parts oil of vitriol and 3 parts water, heated it ascends. The spontaneous inflammability to ebullition (320° to 330° Fahr.), and purifying the vapor as before.
