What Is Impasto?
Thick paint, knife and brush: binders, drying chemistry, Van Gogh to de Kooning, cracking modes, and studio costs today
Impasto is the practice of laying paint so thick that brush or knife marks stand in relief on the support. This guide stays with technique: how binders carry weight, how workshops sequence layers, who pushed the method from Rembrandt's lead white to de Kooning's scraped surfaces, and why conservators treat peaks differently from flat film.
