How can you spot genuine Chelsea porcelain from a photo?

Start with the mark, but don’t stop there. The British Museum lists early incised triangles, later raised, red and gold anchors, made in the mid-18th century. A clear photograph of the base helps to determine whether the piece falls within these ranges. Next, examine the paste and glaze, soft Chelsea paste often has a warm white hue, and the glaze gathers near the relief pieces. Then examine the painting, enamels from this period are thinly layered, and the edges of the rims are worn from use. Look for warning signs, a shiny new anchor on a very worn object, thick glossy paint, or sanding marks under a “cleaned” base. Look for close-up photographs of the edges, handles and joints, and a written description of the condition.
