介绍（中）	半透明的深绿松石蓝色。平坦的垂直边缘;垂直但略凸的侧面，边缘圆润至平底。在外部，紧靠边缘下方的是一条凸起的水平线，两侧是上下的凹槽，另一条凸起的水平线两侧是侧面底部的两个凹槽; 还有一个更宽的凸起同心圆，底部有两个凹槽。完整;针刺气泡;暗淡，深点蚀，彩虹色斑块和奶油棕色风化。外部和内部的旋转研磨痕迹。这些杯子和碗代表了一类色彩鲜艳的半透明器皿，它们在罗马铸造玻璃的曲目中占主导地位，直到它们被无色玻璃制成的容器所取代。与主要在叙罗 - 巴勒斯坦地区制造的马赛克玻璃不同，大多数半透明的单色器皿可能是在意大利作坊制造的，主要在意大利和西部省份的考古遗址中发现。然而，这种浅色船只的流行是短暂的，跨越了大约公元30至70年之间的第一世纪中叶的四十年。由于产量有限，该组明显是同质的，而在它们的马赛克对应物（1972.118.185; 13.198.1-.3）中可以看到形状和调色板的多样性。这类铸造玻璃的主要颜色是深琥珀色、绿色或蓝色、明亮的绿松石蓝和锰紫色。雕刻型材是通过在两个模具之间铸造玻璃坯料，然后在内部和外部进行车床抛光和切割以创建所需的最终形状来形成的。
介绍（英）	Translucent deep turquoise blue. Plain, vertical rim; vertical but slightly convex sides, with rounded edge to flat bottom. On exterior, immediately below rim a raised horizontal line flanked by a groove above and below, another raised horizontal line flanked by two grooves at bottom of side; and a broader raised concentric circle flanked by two grooves on bottom . Intact; pinprick bubbles; dulling, deep pitting, and patches of iridescence and creamy brown weathering. Rotary grinding marks on exterior and interior. These cups and bowls represent the class of brightly colored translucent wares that dominated the repertoire of Roman cast glass until they were superseded by vessels made in colorless glass. Unlike mosaic glass, which was made primarily in the Syro-Palestinian region, most translucent monochrome vessels were probably made in Italian workshops and are found mainly in archaeological sites in Italy and the western provinces. However, the popularity of such lightly colored vessels was short-lived, spanning the four decades of the mid-first century between about 30 and 70 A.D. Because of this limited production, the group is noticeably homogeneous, whereas greater variety in shape and palette can be seen in their mosaic counterparts (1972.118.185; 13.198.1-.3). The principal colors for this class of cast glasses are deep amber, green or blue, bright turquoise blue, and a manganese purple. The carinated profile was formed by casting a blank of glass between two molds, followed by lathe polishing and cutting on the interior and exterior to create the desired final shape.
