Abstract

The invention relates to pressure-proof glass bodies (3) composed of two half-spheres (1,2) comprising or not a cylindrical intermediate part (10) and having complementary surfaces (4) which are brought into contact with each other, whereby the outer surfaces of a formed seam are even and flat. The glass elements are assembled in a non detachable way by gluing them together with a curable glue which is applied to said complementary surfaces. A glued seam (6) which is formed, for example, by a light or heat-curable glue, can be covered with a permanently elastic sealing material and then with a band and/or tape. The inventive glass bodies are characterized in that they are simple to manufacture and safe to operate when they are used in the oceanographic field.
