Boston Valley Terra Cotta is committed to producing the highest quality terra cotta product in the country. We have put a quality assurance program in place that ensures every block leaving our facility will meet our assured standards. The program is in place all the way from clay batching, through extrusion into drying and firing and finally sizing and shipping. Product is checked for conformance to dimensional tolerances after it is dried and after it is fired. Straightness of the panels is checked on a laser controlled tolerance inspection machine which automatically rejects non-conforming panels for recycling. After firing panels are also checked for color range conformance using a photospectrometer. Boston Valley also performs consistent periodic material testing to ensure our clay bodies continue to perform in the industry property testing expected of ceramic materials. Our recipes consistently outperform the industry standards.
