Gas Burner: a Home-Made Bunsen Burner from Brass Tube (Work, 1892)
A Bunsen burner: gas from a fine jet draws air in through two holes at the foot of an upright tube, and the mixture burns at the top with a hot blue flame that leaves no soot. H. B. Stocks (Work, 1892) makes one from a 3 1/2 in. brass tube 1/2 in. across, a short 3/8 in. tube for the gas, a brass boss and elbow from a gas bracket, and a bit of fine-bore tube from an old oil-can as the jet.
A sliding brass collar over the air-holes sets the flame.

"To make a Bunsen burner the following materials will be necessary:—A piece of brass tube 3 1/2 in. long, 1/2 in. diameter (external); a piece of tube 3/8 in. in diameter, 1 1/2 in. long; a brass boss similar to those on an ordinary bracket, but without a tap; a brass elbow tube; also a piece of tubing with very fine bore (small bit of tube from an old oil-can will do)."

Solder the brass elbow-piece onto the brass boss, with the tube that has a screw cut for a gallery uppermost.

Cut the fine-bore tube 3/4 in. to 1 in. long and solder it inside the vertical tube of the elbow-piece so it projects about 1/2 in. If it is too small for the hole, plug round it with a little sheet lead, keeping it perfectly vertical and in the centre of the outer tube, then solder. The metal of the oil-can tube is not given (unknown).

Make the burner tube
Take the brass tube 3 1/2 in. long, 1/2 in. across. If it is not of very thick brass it will be a little too large: turn a piece of very thin sheet brass 1/2 in. by 1 1/4 in. into a cylinder and solder it inside one end. Tap that end inside to screw onto the male thread of the elbow-piece. At the same end drill two holes about 3/8 in. across, exactly opposite each other, their centres 5/8 in. from the end: the air-holes.

Screw the burner tube onto the elbow-piece and screw the 3/8 in. tube, 1 1/2 in. long, into the side opening. Push the india-rubber tube from the gas supply onto the side tube and light. A purplish-blue flame means air and gas are in the right proportion. A yellow tip means too much gas: plug the hole in the jet slightly.

If the gas burns with a green flame and a hissing noise, the air-holes are too large. Cut sheet brass about 3/4 in. wide and 1 3/4 in. long and drill two holes 3/8 in. across, 1/2 in. from each end (their centres 3/16 in. further in). Turn it into a tube and push it onto the burner tube over the air-holes. Turn it until the two sets of holes do not quite match, so the right amount of air reaches the burner.
