“TEARS” IN THE STEM
PLAIN DRAWN LARGE ALE GLASS, SHOWING “TEAR” IN STEM
Many baluster stems enclose a separate blob or bubble of glass, called a “tear.” It has been thought that this was an accidental feature, due to imperfect mixing of the metal and the presence of air in the molten glass. Obviously, that is an unlikely cause, and in the Diary of Mr. Pepys I have discovered a passage which seems to show how these “tears” in the stem would begin. Writing little more than twenty years before 1689, Pepys refers to the “chymical glasses which break all to dust by breaking off a little end; which is a great mystery to me.” These were called lacrymæ Batavicæ, or “Dutch tears,” and were made by letting drops of molten glass fall into water; hissing, the glass became tearlike in shape, a blob with a long slender tail, and hollow. Probably such as these were the “tears” which appear as ornaments within the old drinking-glass stems, distinctly visible and separate from the rest of the glass in the stem, though of the same tinge and quality of material. The name “tear” is to this extent a misnomer, that nearly always the “tear” is bigger at the top than the bottom; whereas a tear proper swells out more the lower it slips on the cheek. But I own a baluster-stem glass in which the lower part of the “tear” is the bigger, and in some such glasses the “tear” swells out or in to match the shape of the stem. Sometimes three or five or more very small “tears” appear in one of the bulbs.
