Pair of Mid-Century Frosted/Etched Glass Salad or Dessert Plates

This is a set of two approximately 8-inch clear glass plates, likely dating from the mid-20th century. The plates feature a shallow well and a wide, smooth rim. Each plate is distinguished by a centralized, frosted motif on the underside of the glass. One plate depicts a detailed rose blossom with leaves and a stem, while the other features a classical neo-Palladian door knocker or heraldic crest motif. The etching/frosting technique creates a soft, tactile contrast against the polished transparency of the glass. The glass appears to be of high quality, displaying good clarity without significant internal occlusions or bubbles. There are no immediate signs of large chips or cracks; however, the surface shows visible 'clouding' or white hazy residues, particularly around the edges and in blotches across the body. This may be stubborn residue, mineral deposits from hard water (often called 'etching' in dishwasher-damaged glass), or remnants of an old adhesive. The style suggests an American glass manufacturer (potentially Heisey, Fostoria, or Cambridge) known for etched decorative tableware during the 1940s-1960s. The uniform construction and centered designs indicate machine-molding followed by a secondary etching or sandblasting process.
