Ivrene is the name given by Mac-Beth Evans to this opaque beige color of Petalware, according to Gene Florence in his book Encyclopedia of Depression Glass. He also states that "soups are seldom seen in Petalware". Petalware was produced by the Mac-Beth Evans Glass Company from 1930 to 1950. These four beautiful cream soup bowls are quite hard-to-find. They measure 4 ½” in diameter. They are in unused condition with no chips, cracks, scratches, or flea bites.
