smokeless

Cressets at the main intersections burned constantly, their smokeless flames lighting the streets poorly.

For above was Crestline—even as the little Croatian settlement had been—smokeless, lifeless.

A small torch, that will give a very fine and hot smokeless flame, can be made from a piece of glass tube, about 4 in.

Of course, the whole difficulty in such cases arises from the invisible fire of smokeless powder.
