Pyrex Pattern Numbers

It wasn't long after decoratively patterned Pyrex moved from single promotional pieces in the late 1950s to spanning full sets of oven and bakeware in the 1960s that Corning saw the need to move beyond the simplistic system of alphabetic pattern initials and color code numbers. To that end, one or two-digit pattern numbers began to be assigned that could be appended to either model or set numbers to create a unique catalog number.

Pattern numbers were assigned roughly sequentially, and apparently without regard to overlapping the color code numbers that came before. The first standard pattern collection to have such a number applied was 1961's Sandalwood, starting with the seemingly arbitrary #5. Patterns #1 through #4 would eventually be included and even recycled for use on later patterns.

In a few instances, pattern numbers were re-used.

Remember that pattern numbers never appear on the pieces themselves. They are seen only in company literature, on cartons, and occasionally in print advertising.
