By the early 1940s, the Old Spice for Men products were so successful, that irregularities with the Hull Pottery (mainly the bottles) slowed down the production lines and caused many bottles to leak through ill-fitting stoppers. Shulton considered using a more uniform product out of molded glass. The Wheaton Glass Company, in Millville, New Jersey, formulated a special milk glass they called "Pottery Glass." It had the heavy look and feel of the Hull Pottery mugs (and bottles) but could be produced faster and with more precision. With slight changes in size, shape and graphics, these glass shaving mugs endured until the early 1990s when Procter & Gamble discontinued the shaving mug and soap product line.
