Original vintage magazine ad, TYGART VALLEY GLASS COMPANY of Washington, PA.  Strong, sturdy vinegar bottle made in the popular squat type.  History of Glass.   The discovery in England of flint glass or lead glass, probably by George Ravenscroft around 1677 was the first really English contribution to the art of glass making.  The beauty of English glass of this period lies in the clarity of the metal rather than any decoration used.  Engraving and cutting were the principal modes of decoration. Old 1938 glass packer industry advertisement.  Would look fantastic matted and framed.
