• Stem - In drinking glasses the stem is that section of the glass that joins the bowl to the foot. In mass produced glasses is usually solid and of cylindrical shape, but in antique drinking glasses it may be long and short and in various styles or with decoration, such as air twist, baluster, collared, faceted, hollow, knopped, teardrop, twisted or incised.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Engraved Glass - The method of decorating glass by marking the surface with a sharp intrument such as a diamond, metal needle or rotating cutting wheel. As pressure is applied to the surface, best results for engraving are achieved if the glass is of sufficient thickness. In the 19th century etching was used to decorate some table glassware that was too fine to take an engraving tool.
• Bowl - With drinking glasses, the bowl is the hollow section of the glass that holds the liquid. Many glasses were mounted on a stem joined to a foot, others were cylindrical, of tumbler shape. The size and shape of the bowl was determined by the type of liquids they were meant to hold. Shapes used included bell shaped, conical (funnel), bucket shaped, trumpet, cup, ogee, funnel, cylindrical and rounded.
