A bullseye (manufacturers’ spelling) is the result of producing crown glass, a common process until the 19th century. The bullseye comes from a mouth-blown rondel that has been cut down to make square or rectangular panes. Before the advent of modern glass manufacture, gaffers or glassblowers made windowpanes for wealthier customers by using only the flat, thinner, transparent outer edges cut from large rondels. The center piece, thicker and more opaque, “flawed“ by a break-off pontil mark (navel) and ripples, went to a less fussy buyer or was used in an outbuilding.
