Inspired by classic tomato red reduction glazes, Ancient Copper is an iridescent, iron red glaze that breaks dark brown over texture and pools dark yellow-green, giving it a weathered appearance. Due to the powdered nature of the materials involved with the dry-mix dipping buckets of this product, their respective health information and labels differ from the brushing glazes. *Note that all dry dipping glazes can be difficult to layer. Dipping glazes behave differently from brushing and they require thorough testing prior to layering full piece. Safety Warning Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
