To Make Lampblack

This can be prepared on a small scale in the following manner: Suspend over a lamp a conical funnel of tin plate, having above it a pipe to convey from the apartment the smoke which escapes from the lamp. Large mushroom-like concretions of a very black carbonaceous matter, and exceedingly light, will be formed at the summit of the cone, and must be collected from time to time. This black may be rendered less oily and drier by calcination in close vessels. The funnel should be united to the pipe, which conveys off the smoke, by means of wire, because solder would be melted by the flame of the lamp.
