More restrained, but similar to a regular blue glaze, Iron Lustre is brown where thin with blue-gray floats where thick. It is beautiful on texture and layers well with other Potter's Choice glazes. 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.
