- Vintage Pyrex Bowl - Terra pattern, the first pattern released on both ovenware & tableware. - Black w/ light brown stripes - Style: Mid-Century Modern - Pyrex advertised it as "New, earthenware look, new texture...contemporary as well as classic". According to the Corning Museum of glass: - This pattern was introduced in 1964 & discontinued in 1965 when production costs & retail price proved to be too high. - Terra, meant to mimic the look of earthenware, is one of the most unique designs ever released on opal Pyrex - Designer William Curtis won an award for his concept. - The process to create this design involved applying the brown background & firing it on followed by the application of the charcoal overspray via an automatic scratching technique. The goal was to create the effect of a potter’s wheel application known as graffito. Corning even trademarked the name Graffito, but ended up going with the more evocative descriptor, Terra. MARKS: (in raised lettering on the bottom) - 404 - 4 QT. - Trade Mark - 25 - PYREX - ® - Made in U.S.A. - Ovenware CONDITION: Very good vintage condition with the caveat that there are the scuffs you find in vintage (60-year-old!)
