Two portraits from the collection of Jaroměřice nad Rokytnou Castle were used as examples to examine the painting's technique and technology. Evidence was provided that Gabriel Müller proceeded from the broadly used painting technique on a toned bole underlay. Pigments typical of 18th century painting were identified in the Müller's work of art. The research results provided valuable information for the interpretation of Gabriel Müller's painting style. The acquired data deepened the previous knowledge and served as a primary corrective for a comparison with Johann Kupezky's painting technique. The interpretation took into account a wider technology context of 18th century fine art techniques.
