![]() ![]() Dimpled glasses are now rarer than the other types and are regarded as more traditional. These design features became less important when manual washing was superseded by machine washing from the 1960s onwards. The dimples prevent the glass slipping out of the fingers in a washing-up bowl, and the design of the glass emphasises strength, helping to withstand frequent manual washing. They are moulded with a grid pattern of thickened glass on the outside, somewhat resembling the segmentation of a Mills bomb. Jug glasses (or " dimple mugs") are shaped more like a large mug with a handle.In the United Kingdom, this style was popularized after World War II, with Ravenhead Glass introducing a Nonik glass in 1948. The original motivation for the glass was to reduce breakage when stacking (40% greater crushing strength and curved surface where rim touches), reduce breakage when tipped over (due to the bulge protecting the rim from impact), improve grip, and facilitate cleaning (due to shallow curves, compared to more severe curves). The design was preceded by many other bulged glass designs, dating to the mid-19th century, which differed in having a severe bulge and different purposes (a stop for a jar cover, or placement in a soda glass holder), rather than the shallow bulge of this design. This design was invented by Hugo Pick, of Albert Pick & Co., who was awarded two US patents: design patent 44,616 (2 September 1913) and patent 1,107,700 (18 August 1914), although the design patent was invalidated, and which was commercialized as Nonik (for "no-nick"). Nonik pint glasses: full and half pintThe nonik (or nonic, pronounced "no-nick") is a variation on the conical design, where the glass bulges out a couple of inches from the top this is partly for improved grip, partly to prevent the glasses from sticking together when stacked, and partly to give strength and stop the rim from becoming chipped or "nicked". ![]() The most common size found in the US holds 16 US fl oz (473 ml) to the rim. Also called a "shaker pint" in the United States, as the glass can be used as one half of a Boston shaker. ![]()
