By means of the rod spoken of, this mixture can be pushed out of the glass tubing, and can be cut up into pieces of the length desired by means of a penknife, and a fine platinum wire attached. They may be kneaded with the fingers a little and then dried gradually in an oven. placed on the burner and the hydrogen flame only applied the lump will contract and become exceedingly hard. oxygen is turned on the result is an exceedingly intense flame without very much heat.
