Apparatus for coating articles with enamel slip comprises an evacuatable container 1, which is divided in a vertical plane into parts 2, 3, which are movable toward and away from each other. The articles 29 to be coated are suspended in a row from an endless conveyor track and are introduced into the container 1 when its parts 2, 3 have been moved apart to open the container 1. The container 1 is then closed. In the closed container, the suspension means are held between soft seals 12, 13 which cover the confronting edges of the container parts 2, 3. When the container 1 has been closed, the air contained therein is sucked off and slip is sucked into the container. As soon as the coating operation has been completed, the slip is drained from the container 1 and the latter is then opened and the coated article is removed.
