Druware

[3] "American housewives have been snapping up the Evans-designed green, blue and yellow 'cook-and-serve' vessels faster than many stores can keep them in stock.

Known as Royal Dru, the cookware is the adaptation of a 200-year-old Dutch process of fusing iron to enamel so that it won't crack or chip from heat or rough handling.

[4] The most popular line of Druware came in pastel shades of Delft Blue, Tulip Yellow, and Key Largo Green, and was recognizable for the hand-painted tulip, windmill, and fleur-de-lis decorations on the sides and lids of each piece.

Despite Druware's popularity with home cooks, venerable chef James Beard was less impressed.

"[11] After natural gas became popular in the Netherlands in the 1960s,[12] DRU ceased the production of cookware, and began producing fireplaces, wall heaters, and wood stoves.
