An excellent bunsen burner for small work can be made as follows: Draw a glass tube to the shape shown, to produce a fine hollow point. Mark carefully with a file and break at A and then at B. Bore or burn a hole in a cork to fit the tube. Cut a V-shaped notch in the side of the cork extending to the hole. Bend the lower tube at right angles and insert it in a wood block, previously slotted with a saw to make a snug fit. A little glue will hold the glass tubes, cork and base together. The air mixture can be adjusted by sliding the upper tube before the glue sets.
The burner is especially adapted to continuous work, such as sealing packages, etc. The flame will not discolor the wax. - Contributed by E. P. Ferte, Spokane, Wash.
