Cornflower was CorningWare's first decorated pattern (introduced 1958) and remained in continuous production until 1988 — that means the pattern is plentiful at the entry level. The price spread is form-driven: common casseroles sell at the bottom of the range, while specific rare forms (the percolator especially) drive serious collector premium.
The Cornflower electric percolator (P-156, P-157, P-167 depending on capacity) is the single most-hunted piece. Production was limited, the form is fragile, and the electric base is often missing or broken on surviving examples. Complete percolators with working bases regularly clear $180-$300; mint examples with original cord and instructions can fetch $400+. If you spot a Cornflower percolator at an estate sale priced under $50, buy it before reading the rest of this paragraph.
CorningWare was a wedding-and-housewarming staple, which means a surprising number of pieces survive in original boxes — but most boxes were thrown away. A complete original boxed set with paperwork sells for 3-4x the price of the same pieces loose. The "shopping set" gift boxes from the 1960s are particularly collectible because they tell the marketing story of the era.
World Kitchen acquired CorningWare in 1998 and reissued the line in a stoneware body. The reissue uses the same Cornflower pattern but is heavier, not stovetop-safe, and not made of the original Pyroceram material. Vintage collectors specifically want the Pyroceram pieces (1958-1988). The bottom mark is the fastest tell — vintage pieces say "Corning" or "CorningWare"; reissues say "World Kitchen" or similar.
Cornflower has the broadest geographic distribution of any of these vintage glassware categories — these were everyday wedding gifts across the entire country from the late 1950s through the 1980s. Estate sales in any region surface them weekly. eBay and Facebook Marketplace both have active buyers; the difference comes down to shipping cost (these are heavy, often $15-$25 to ship) which often makes local sales net higher on the casserole-sized pieces.

Yes. Vintage Cornflower CorningWare (made 1958-1988) was engineered as Pyroceram cookware — thermal-shock resistant, microwave-safe, oven-safe to 500°F, and stovetop-safe on direct flame for the bottom-burner pieces. The blue pattern is printed under a sealed glaze and does not contain lead or cadmium. The only common-sense limitations: avoid extreme temperature swings on pieces with visible chips or hairline cracks, and don't use cookware-grade abrasives that could damage the printed pattern.
The Cornflower percolator (model P-156 / P-167) is the most-hunted piece — production was limited and the form is fragile, so survival rates are low. Mint-condition percolators with original electric base routinely clear $180-$300. The original boxed shopping sets and complete nesting bowl sets with all four pieces are next, often clearing $120-$200. Individual saucepans and casseroles are common and inexpensive; the rarity hierarchy is form-driven, not pattern-driven.
World Kitchen (later Instant Brands) reissued CorningWare in a stoneware-bodied version after acquiring the brand in 1998. The reissue looks similar but is heavier, does not contain Pyroceram, and is not stovetop-safe. The vintage Pyroceram pieces are uniformly thinner, lighter, and have a slight translucent glow when held to light. Bottom marks are different — vintage pieces are stamped "Corning" or "CorningWare", reissue pieces carry "World Kitchen" or current ownership marks.
