考古陶瓷器皿中经常发现沥青化合物。由于它们的存在可能会影响油或酒渗透到陶瓷织物中，因此进行了实验，其中脂质或多酚扩散到倾斜和非倾斜的现代容器中，然后进行化学分析。结果表明，葡萄酒中的多酚甚至可以透过沥青层侵入陶瓷中。因此，考古碎片中不存在多酚并不是因为它们无法到达沥青层下的陶瓷基质。相比之下，沥青层对于避免油侵入陶瓷基体非常有效。因此，油罐在使用前在内部涂上沥青似乎是合乎逻辑的。将沥青陶瓷同时暴露于油和酒的实验表明，酒使沥青更容易渗透脂质化合物。这些实验数据与在土耳其萨加拉索斯出土的双耳细颈瓶碎片上获得的残留物分析结果相对应。沥青和油经常一起被发现。根据多酚测试，只能从两个容器中获得葡萄酒储存的指示。在此背景下，讨论了 Sagalassos 双耳细颈瓶的可能用途，并对松脂与考古双耳细颈瓶中葡萄酒储存的传统关联进行了严格评估。
Pitch compounds are frequently identified inside archaeological ceramic vessels. As their presence might affect the permeation of oil or wine into the ceramic fabric, experiments were conducted in which the diffusion of lipids or polyphenols into pitched and non-pitched modern vessels was followed by chemical analysis. Results show that the polyphenols of wine can intrude into the ceramics even through a pitch layer. Consequently, the absence of polyphenols in archaeological sherds is not due to their inability to reach the ceramic matrix under the pitch layer. By contrast, a pitch layer is quite effective to avoid oil intrusion into the ceramic matrix. Thus, it seems logical that oil amphorae would have been coated with pitch at the inside prior to use. Experiments in which the pitched ceramic was simultaneously exposed to oil and wine, show that the wine makes the pitch more permeable for the lipid compounds. These experimental data are confronted with residue analysis results obtained on amphorae fragments excavated in Sagalassos, Turkey. Pitch and oil were frequently found together. Based on a polyphenol test, indications for wine storage could only be obtained for two vessels. Against this background, the possible uses of the Sagalassos amphorae are discussed, and the traditional association of pine pitch with wine storage in archaeological amphorae is critically assessed.
