This photo illustrates another lost art form. It is an example from the "bottles glued together and painted with frosted crackle glaze" movement.
I believe the original idea was to create lovely candle holders to accent the decor of any room, but I don't think anyone would think these tall...results... would be safe with a lighted flame!
I recall my mother and one or two of her friends practicing this 'art' in about 1969 or 1970. Bottles were collected, along with baby food jars for the candle holding tops. Of course, a variety of different shaped bottles were more effective than stacked mayonnaise jars and ketchup bottles, so friends were pressed to finish up that last bit of Worcestershire or soy sauce and donate the bottles to the project.
I think that Mother had someone use a glass cutting tool to cut off the threads that originally secured the lids to create a smoother effect.
I don't recall any of the finished projects in our house, so I think that the project may have been to create centerpieces for an event. I am assuming if there was any fire 'incident', I would remember hearing about it, but I can't be sure.
I don't think that I have ever seen an example of this craft at an estate sale, thrift store or antique mall. Have you?
