These PYREX salt and pepper sets were released in 1960 with turquoise, pink, pale yellow and white tops. They originally retailed for $1.49 for the set. Sets were designed to match PYREX bakeware in turquoise, pink, pale yellow and opal which was available during the same time period. Each set was made of thick glass with a gold-embossed “S” or “P.”

Although they lack the familiar embossed PYREX marking, they appear in PYREX dealer
catalogs in 1960 through 1963. In 1964 and 1965, only the white-top set was listed, so it’s uncertain if pink, turquoise and pale yellow were still sold or if they had been discontinued.

In the early 1970s, Corning launched a full-line of PYREX Compatibles to coordinate with Corelle Livingware patterns. The first salt and pepper sets in the PYREX Compatibles line, all launched in 1972, were Spring Blossom Green, Butterfly Gold, and Snowflake Blue. When these items made their debut, salt and pepper sets were sold in white, applied to clear glass, with the matching design. The white paint, which was prone to chipping, was replaced with clear glass in 1975.

The white background was available until 1974 on Spring Blossom Green, Butterfly Gold, Snowflake Blue, and Old Town Blue. Old Town Blue was somewhat unique in that the PYREX tabletop items did not have a line of matching PYREX mixing and bakeware sets. However, marketing materials after 1976 advertised that Old Town Blue was an ideal companion to the newly released PYREX Homestead pattern.
