Layered glass products such as multilayer glass rods or fibers are formed in a preferably continuous process wherein at least two component glasses (A, B) are supplied to an annular mixing zone (20) wherein relative movement of the annular surfaces (22, 24) produces spiral layering of the glasses (A, B) and the formation of a glass product stream having a preselected gradient in composition and glass properties across a diameter thereof. |
