Glassware of Olginsky glass factory in the Tomsk Regional Museum n.a. M.B. Shatilov: the problem of attribution

Archaeological objects, replenishing museum collections, become museum objects with the information contained in them. glass objects were found with stamps “Z.I.T.G” and “O.ZT.G.I.1868” and a variety of internal bubbles in Tomsk, 2015. It is assumed that the items “were released by the oldest glass producer in the Tomsk province - Olginsky glass factory”. It is necessary to confirm the belonging of items with the stamp to Olginsky glass factory and to prove that these glass items correspond to the technology of product development at this plant. 9 fragments of glass were replenished with Tomsk Regional Museum' funds: 4 with the stamp “O.T.T.GI”, 5 “O.Z.T.G.I.1868.” in 2018. To decipher the stamps, we give archival data on glass factories, Tomsk province in the years 1860-80. In the Tomsk province there were 6 glass production: Olginsky glass factory, a plant in the Nelyubinsk volost, glass production K.P. Platonov in the Altai district, plant N.I. Minsk near Tomsk, plant B.I. Kurlandy along the Irkutsk road and a glass factory near the village of Luchanovo, Tomsk province. The largest production was Olginsky glass factory. The glass factory belonged to the merchant E. Isaev, located in the Tomsk province, in the Bogorodskaya volost, near the village. Olgo-Sapezhenko, produced drinking products. Consequently, the deciphering of the stamps on 9 museum objects is connected precisely with the Olginsky glass factory: “Olginsky glass factory of Tomsk Province by Isaev”. The analysis was performed using a scanning electron microscope with an energy dispersive attachment in the laboratory of the Department of Silicate Technology and Nanomaterials of the Scientific and Educational Center n.a. N.M. Kizhner of Tomsk Polytechnic University to establish the composition of museum objects in 2018. Electron microscopy images confirmed the presence of air bubbles in the glass indicated in the attribution of museum objects. According the archival sources, for the production of glassware at the Olginsky glass factory was used sand, lime, “guzhir”, quartz, soda, nitrate, and “potash”. Laboratory data on the formulation and quality of the glass analyzed in general are similar to the data on the glass composition of the Olginsky glass factory, recorded in archival sources. The indisputable fact of the existence of the Olginsky glass factory in the Tomsk province is confirmed by archival documents and archaeological finds. Museum objects made of glass correspond to the technology of making products of the Olginsky glass factory, which was located in 1860-1880 in the territory of Tomsk province. Tomsk Regional Museum' funds: were replenished with genuine museum pieces from the production of the Olginsky glass factory.
