And there are plenty of Pyrex patterns that are discontinued, so they can only be purchased secondhand. One interesting pattern you might want to add to your own collection is the Terra pattern, which was released in 1964 before being discontinued only a year later. Unlike many patterns of the time, this striped pattern was given the Terra name at the time of its release. Designed by William Curtis, who won an award for this design, this pattern was meant to give you the look of classic earthenware. The Terra pattern was released on a number of Pyrex pieces, including their tableware line.
