Packaging Update - July 2026
We're sharing an update on our product labels, and thank you for your patience throughout this process. AMACO products with updated labels that include redacted information are now shipping.
We made these redactions as a precaution while we review California labeling requirements and improve the clarity of the information we present to our customers. Our team is actively working on future label updates to make product information easier to understand and more helpful for the end user. We appreciate your grace and understanding as we work through these improvements.
Most importantly, the redactions on our labels do not indicate any changes to our product formulations. The products inside remain the same trusted formulas you know and rely on. These updates are limited to the information displayed on the label and do not reflect any changes to product performance, quality, or safety. Thank you for your continued support and patience as we work to provide the clearest, most accurate labeling possible. Thank you for using AMACO products!!
Packaging Update - June 2026
You may notice some markings on our labeling. These are temporary as we transition to new labeling to ensure compliance with California labeling law. The new labeling does NOT mean anything has changed in the formulation of our products, nor does it mean our products are unsafe for use. We are making this change to minimize frivolous lawsuits.

California has very broad chemical warning and advertising laws that allow a plaintiff to file failure-to-warn and false-advertising lawsuits and recover penalties and attorneys’ fees, even if the product is safe to use and no one was injured. Given that many companies targeted with these lawsuits pass the cost of six-figure litigation settlements on to customers, we have decided to revise our labeling now to avoid this possibility and keep our focus on our customers. We have offered quality products to our customers for decades and are grateful to them for their trust in us. Our products are regularly tested and evaluated for their safety.
Since 1940, AMACO products have been certified by the Art & Creative Materials Institute, which requires our products to be evaluated for safety by board-certified toxicologists using ASTM test methods. You will see that our labels carry two seals.

The Approved Product “AP” seal.
This signifies the product is safe for all ages when used as intended.
The Cautionary Label “CL” seal.
This advises that the glaze product contains soluble copper, which, if ingested in sufficient quantities, can irritate the stomach lining.
In addition, all AMACO glazes and underglazes are tested for lead and cadmium in compliance with industry-standard ASTM test methods C927/C738, and they also meet the FDA’s guidelines for dinnerware safety.
Finally, AMACO products continue to be labeled in accordance with the Federal standards of the “Labeling of Hazardous Art Materials Act” (LHAMA). In fact, the Art & Creative Materials Institute’s certification program served as the framework for developing the Federal standards.
