ABSTRACT:
A molding system for large-scale containers using closely-spaced bladders, one inside the other, to contain a resinous material that will harden to form a rigid container. The bladders float in a liquid of the same specific gravity as that of the resinous material, and the inner bladder is filled with a liquid of the same specific gravity. The inner bladder may be filled first to establish the size or volume of the container, and then the resinous material may be filled between the inner and outer bladder layers whereat it will harden to form the container.
