In 1986 this style of mug, made of Suprema glass-ceramic, replaced opal Pyrex round-bottom cups in the Livingware line. They are the same shape as Dimension IV's Pyrex flared mugs from 1979, but in Suprema, they are noticeably thinner. Dates pertain to this cup style in general; the date range of each individual pattern varies.
Suprema also has a translucency that is comparable to Vitrelle, and holding it up to a bright light is an excellent way to distinguish it from Corning Ware or Centura. The latter two materials are densely opaque, and light does not pass through them easily.
(Photo: Two of three possible Suprema flared mug backstamps.)
Flared mugs made of Suprema have three possible backstamps. One says: "CORNING USA ... M'wave OK" and another says "CORNING USA ... Microwave Safe". Of these two it is not clear which is older or newer, but the third backstamp (not pictured) is certainly newer than the first two. It reads simply: "CORNING ... Made in USA".
All backstamps are printed with embossed letters, but they are distinctly different from Pyrex markings. Suprema stamps say very little, with larger lettering that is low on the surface and often feels slightly rough.
Although the backstamp does not mention it, this shape does have a model number: 111.
Beige Suprema mugs: Forever Yours, First Of Spring, English Breakfast.
Initially, Suprema glass-ceramic was made only in white, but a beige version became available about 1991. Flared Suprema mugs were still in production in 1998, but by 1999, they had been replaced by solid-coloured stoneware mugs with a completely different shape.
Newer stoneware mugs also exist with a flared shape. The handle is slightly different though and their backstamp clearly indicates that they are stoneware.
In the product lines corresponding to this cup style, matching cream & sugar sets were no longer manufactured by this time.
