— But to secure steadi- ness of flow and safety^ it is always better to pass the gas through an acetylene burner or tip, which differs from the tip of an ordinary gas jet only in that instead of a slit there are two very small openings drilled, oblique to each other. See Fig. 40 ; a is a cross-sectional and I the top view. These tips are very cheap, and safe because the openings for the exit of gas are so small that the flame cannot pass back into the generator; c shows another form of tip freq...uently used. The two openings compel the issuing jets of gas to strike each other obliquely, as in a, 44. Characteristics of Acetylene. — Acetylene is a color- less gas, of an ethereal odor when perfectly pure, but as CARBON AND A FEW COMPOUNDS 151 ordinarly obtained it is very offensive to the smell. It is soluble, volume for volume, in water and very explo- sive when mixed with oxygen or air. An ordinary jet of acetylene burns with a yellowish flame, and owing to the large proportion of carbon, — over 92 per cent, — it gives off considerable soot.
