萨米亚陶器（英语：Samian ware）是一种烧制的粘土陶瓷，在公元前50年至公元200年期间在法国的一些地点生产，并在西欧广泛交易。它有一个高光泽的表面，形成了一个非石灰质粘土滑的应用程序，以绿色机构之前，烧制。新的扫描电镜观察表明，滑移层经常开裂，虽然裂纹通常是不可见的肉眼。我们讨论了银纹的机制，并表明，开裂是由再羟基化（RHX）水分膨胀。观察和分析有助于理解考古陶器的RHX测年，表明银纹网络允许水分通过滑动层有效传输。
Samian ware (or terra sigillata) is a type of fired-clay ceramic produced at a number of sites in France in the period 50 BC to 200 AD and widely traded in Western Europe. It has a characteristic high-gloss surface, formed by application of a non-calcareous clay slip to the green body before firing. New SEM observations show that the slip layer is frequently crazed, although the cracks are not usually visible to the unaided eye. We discuss the mechanics of the crazing, and show that the cracking is driven by rehydroxylation (RHX) moisture expansion. Observations and analysis aid in understanding the RHX dating of archaeological pottery by showing that craze networks permit efficient transport of moisture through the slip layer.
