The northern slope of Mt. Vesuvius contains some interesting archaeological sites, including the site discovered in the town of Pollena Trocchia, where the remains, dated to between the 79 and 472 CE eruptions, document the transition from the Roman to late Roman cultural and socioeconomic settings. Profound changes occurred in this time interval, which can be inferred from changes in the ceramic manufacturing processes. Common wares, as the most widespread ceramic class in the archaeological record, are a useful example that illustrates this technological transformation. Seventeen samples of tableware, distinguished into three ceramic classes according to the method of slip application (i.e., Slipped Ware, Painted Ware “a straccio,” and Painted Ware), were analyzed. The results highlight the use of high‐CaO clayey raw materials compositionally similar to Apennine clayey deposits. The clay bodies were occasionally tempered with sandy‐silt materials composed of volcanic grains with lesser amounts of siliciclastic fragments. Firing temperatures ranged from 800 to 950°C, as suggested by quantitative X‐ray powder diffraction and microstructural analyses combined with colorimetric measurements of the ceramic bodies. Micro‐Raman analyses performed on slips revealed the use of ochre for decorating the vessels; it was applied in a different way, representing an actual technological change.

维苏威火山周围晚期罗马装饰餐具的生产技术：来自Pollena Trocchia（意大利坎帕尼亚地区）的证据

山的北坡 维苏威火山包含一些有趣的考古遗址，包括在波列纳·特罗基亚镇发现的遗址该遗址的遗迹可追溯至公元79年至472年之间，记录了从罗马到晚期罗马文化和社会经济环境的转变。在此时间间隔内发生了深刻的变化，这可以从陶瓷制造工艺的变化中推断出来。作为考古记录中最广泛使用的陶瓷类，普通商品是说明这种技术变革的有用例子。分析了十七种餐具样品，根据滑动应用方法将它们分为三个陶瓷类别（即，滑动餐具，彩绘餐具“ straccio”和彩绘餐具）。结果突出表明，使用了与亚平宁粘土质沉积物成分相似的高CaO粘土质原料。粘土体有时会用含火山灰和少量硅质碎屑的砂质材料回火。定量X射线粉末衍射和显微结构分析以及比色法测量陶瓷体的结果表明，烧结温度范围为800至950°C。对卡瓦进行的拉曼分析表明，使用of石来装饰船只。它以不同的方式应用，代表了实际的技术变化。
