This set of 4 French casserole dishes were produced by Glasbake after 1961 since the mark in the bottom has a J indicating made by Jeanette. Glasbake had an early advertising brochure as a "sanitary baking ware and serving ware combined". Each of the 4 bowls hold 11 oz.. Only one has a slight crazing line in it which does not affect its use as you cannot feel it to the touch( pictured).
Materials: Glass.
