Vintage Fire-King Peach Lustre Oval Casserole Dish

This is a vintage oval-shaped baking or casserole dish, identified by its distinctive iridescent finish as Fire-King's 'Peach Lustre' glassware produced by Anchor Hocking. The dish features a luminous, metallic copper-to-peach pearlescent glaze on the exterior, while the interior remains a smooth, milky white opaque glass. The piece is constructed from heat-resistant milk glass (borosilicate or tempered soda-lime), a hallmark of Mid-Century American kitchenware. Its profile shows a shallow depth with curved sides and a subtle rim, characteristic of individual gratin or serving dishes from the 1950s or 1960s. The surface reflects light with an oil-on-water high-gloss sheen typical of the lustreware technique. In terms of condition, the piece appears well-preserved with a strong, consistent shine; however, lustreware is prone to 'dishwasher wear' where the iridescent layer can thin or rub off over time, so careful inspection for minor surface scratches or dulling is necessary. There are no visible chips, cracks, or heavy carbon staining from oven use. The craftsmanship is industrial but high-quality, designed for durability and a decorative transition from oven to table.
