The Regency shape was developed from the end of December 1965 to June 1966. The first few items were test pieces such as a teacup and creamer. These new items had "ribs on the bottom" as noted in Homer Laughlin's modeling log. Three 10" plates, with and without ribs, were then created. Work on developing Regency stopped in mid-January 1966 while one of the newest shapes at the time, Dover, was being expanded. On February 26, attention was again given to Regency and a new straight cup with ribs was made.
From March 1 to July 1, the following pieces were modeled for Regency: saucer, two styles of cups, coffeepot, sugar, creamer, sauceboat, sauceboat stand, lug soup, dinner plate, casserole, fruit cup, tow sizes of nappies and platters, butter cover, coupe soup, two teapots, jumbo cup, salad bowl, snack plate, and shakers. While a total of three cups had been deigned, only one was put into production. The butter cover with its Regency ribs was mated with the plain butter base from Orbit. The ashtray was picked up from the Victoria shape.
In September 1966, some changes were made. The Regency sauceboat was remodeled and three new items were added: 5" dish, coffee saucer (to go with the jumbo cup), and a 6" plate. After these three pieces, there were no more items added, nor were any of the existing shapes revised.
Compared to other shapes introduced in the 1960s such as Orbit, Dover, and Granada, Regency is rather hard to find. Large plates and platters are usually marked with a Homer Laughlin backstamp, but as with other shapes of the time the hollowware was never marked. Expect hollowware to have exterior solid colors with contrasting white lids and flatware to have stylized treatments. In a few cases, Regency can be found in the brown glaze used in Fiesta's Sheffield Amberstone. The two most common treatments on Regency are pattern Reg-801, "Malibu" and the supermarket promotion, "Sheffiled Serenade."
