Since the late 1970s, after a long break, they resumed the investigation of the collections of Russian art of the 18th – early 20th century. The first work was the catalogue of O.A. Adamaitis “Russkaya keramika XVIII – XX vv.” (M., 1976) [Russian Ceramics of the 18th – 20th cc.] presenting a small collection of porcelain, including works of the famous Russian plants. Later that collection was twice enlarged mainly by the items of the second half of the 19th – early 20th century, acquired during expeditions. It was presented by a series of exhibitions and the catalogue “Farfor, fayans. Novye postupleniya 1978 – 1985” (Porcelain. Faience. Recent Acquisitions of 1978 – 1985), written by Zaritskaya O.I. and Shitova L.A. The included tables of trade marks of the porcelain plants were of great value for all porcelain investigators.

The collection of painted enamel of the 18th - early 20th century was difficult for attribution, yet it was systematized and published in the catalogue “Zhivopisnye emaili v sobranii Zagorskogo muzeya-zapovednika” (“Painted Enamel in the Collection of the Zagorsk Museum-Reserve”. In other works L.A. Shitova tried to present conceptual development of the Trinity (the Trinity-St. Sergius Lavra) and Rostov enamel schools and their relations.

The catalogue of Baranova G.K. “Zoloto-serebryanoye kruzhevo XVII – nachala XX vv. v sobranii Sergievo-Posadskogo muzeya” (M., 1993) [Gold and Silver Lace in the Collection of the Sergiev Posad Museum] reflected a specific Museum collection. The introduction of the collection might inspire further investigations of this rare art. G.P. Cherkashina’s catalogue “Artistic Cast Iron of the 19th – 20th Century” (M., 1998) presented the collection formed by the Museum.
