On the vessel’s neck, there is a round stamp ~30 mm in diameter, depicting the bust of an emperor encircled by an inscription. It resembles stamps on amphorae made in Alexandria and the Geronisos Island. The inscription reads, “επί Πτολεμαίου επάρχου”. The gas chromatography–mass spectrometry analysis revealed dehydroabietic acid, methyl dehydroabietate, norabietatrienes, retene, and other phenanthrene derivatives, suggesting that the substance resulted from dry distillation of wood of the Pinaceae family. The headspace analysis yielded components of turpentine oil such as α-pinene, camphene, limonene, cymenes, and others terpenes. To establish the sample’s origin, the amphora’s content was compared with modern pinewood tar obtained by the traditional method. Given nearly identical chromatogram profiles of the amphora’s contents and of tar in areas relating to resin acids, similar values of peak areas of biomarker components, and the presence of turpentine oil components in the sample, it is highly probable that the amphora indeed contained tar.</p></abstract><kwd-group xml:lang="en"><kwd>Late Roman amphorae</kwd><kwd>Black Sea</kwd><kwd>tar</kwd><kwd>pitch</kwd><kwd>gas chromatography</kwd><kwd>mass spectrometry</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This study was carried out in the “Tauric Chersonese” State Museum-Reserve and the Center for Collective Use “Analytical Center of St. Petersburg State Chemical and Pharmaceutical University”, supported by Grant 075-15-2021-685 26/07/2021, as well as under the “Priority 2030” Program of Sevastopol State University (Strategic Project No. 3).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bonaduce I., Ribechini E., Modugno F., Colombini M.P. 2016 Analytical approaches based on gas chromatography mass spectrometry (GC/MS) to study organic materials in artworks and archaeological objects.
