<P> In the early to mid-1800s, glass blowers began to use molds and several different patterns of "whiskey tasters" in several different colors were being made in molds . These glasses are also thick like today's shot glass but they will have rough pontiled bottoms from being hand blown into the mold . By the 1870s to 1890s as glass making technology improved, the rough pontiled bottoms largely disappeared from glasses and bottles . </P> <P> Just before Prohibition in the U.S. in the late 1800s to early 1900s, thin - sided mass - produced whiskey glasses were common .
