These 2" diameter x 1.5" deep aluminum fuming dishes are ideal for use with cyanoacrylate and a hot plate. Place five to ten drops of cyanoacrylate into a dish and place on a hot plate. Include a cup of warm water in the fuming chamber to add humidity and activate the hot plate. Time or watch the fuming process, as it is easy to over fume when heat is applied. Each pack includes 100 individual dishes.
