Evaluate the signature on the bottom. While Roseville Pottery signatures changed throughout the lifetime of the company, The Roseville Exchange asserts fakes are most often signed "Roseville USA" in low relief, or "Roseville" with a blank space where the "USA" should be.
Make sure glazes are bright and contain depth. The Roseville Pottery Exchange explains that forgeries have flat glazes that don't allow the color of the clay beneath the glaze to shine through.
Look for finely crafted handles. Because master artisans have not created Roseville reproductions, handles tend to be clunky and lacking detail.
Find detail in the decorations. Whether the piece bears a peony, white rose, or zephyr lily in decoration, leaves, petals, or vines should all contain intricate artistic detailing.
Ask the seller for additional information. Whether the piece is being sold in-person or online, contact the seller to ask about the date of manufacture, where the piece was purchased, and what makes the piece true Roseville. Reputable dealers will share their knowledge.
Become familiar with true Roseville pieces. On reproductions, slight differences in overall shape and pattern will exist because fakes are not made from original molds. The more you familiarize yourself with the nuances of true Roseville pottery, the easier it will be to recognize an authentic piece.
