Grounds in Rembrandt’s workshop and in the paintings by his contemporaries Karin Groen Netherlands Institute for Cultural Heritage Rembrandt Research Project
Research Kühn 1962 to 1965 48 painting attributed to Rembrandt 10 shop works or contemporary copies 38 other Dutch painters from the 17th to 19th century By 1965, the grounds of 122 paintings on canvas and panel from various periods ascribed to Rembrandt had been examined.
New sampling necessary for obtaining insight into the occurrence and distribution of the quartz ground! Criteria for sampling: Paintings by Rembrandt and those ascribed to him: As many works on canvas as possible from Bredius (1935) Pictures by Amsterdam painters who had nothing to do with Rembrandt Pictures made between 1640 (Night Watch) and 1669 (Rembrandt’s death)
Results 160 canvas paintings investigated 125 of these made after 1640 48 on a quartz ground: almost half of the production None of the 60 non-Rembrandt paintings made in Amsterdam 1640-1669 has a quartz ground
Canvasses with a quartz ground were used exclusively in Rembrandt’s workshop These canvasses must have been prepared in Rembrandt’s workshop This find provides a strong supplementary criterion for attributing paintings: Every Rembrandtesque painting on a quartz ground derives from Rembrandt’s studio !!
Rembrandtesque ‘Self-portraits’ Staatsgalerie Stuttgart c.1659 Corpus IV17 Fogg Art Museum Cambridge Mass. c.1660 Corpus IV22 National Gallery of Victoria Melbourne c.1660 Corpus IV21
What could have been the reason for Rembrandt using quartz grounds? Quartz ground is clay with a high proportion of ground up sand River clay as used by potters and for making bricks, recommended for priming canvases in written sources, abroad.
Clay for bricks and pottery under the microscope Old sea clay, Makkum River clay, from quarry for bricks River clay, from quarry for bricks, Bruggen, near border Germany Clay along the Old Rhine
