DOG'S DREAM ORNAMENT: HYDRANT

Glass has existed since the beginning of time.  It was first found in nature as obsidian, formed by the fusion of rocks and sand under the terrific heat of volcanic action. Today's scientists disagree over the earliest man-made glass, but the art of glass blowing was discovered in the Sidon - Babylon area some time about 250 B.C. The long metal tube used in the process has changed very little since then.
