Glass and metal are integrated, giving it an astonishing strength as a glass product.
The metal-fused sight glass, Clinport(R), is a product born from a revolutionary technology that powerfully and hermetically fuses special glass directly to the inner wall of a metal ring, while utilizing the difference in thermal expansion coefficients between the metal ring and the glass to enhance the glass. It has obtained patents in Japan and the United States, proving the uniqueness and excellence of its technology. Since the glass and metal are integrated, it possesses an astonishing strength for a glass product. Therefore, there is almost no concern about glass breakage. If the glass does break, the damage remains confined to the surface layer, appearing in thin, flake-like pieces, and the destruction progresses gradually, which prevents the contents from spilling out in the event of a breakage, thus earning high safety ratings.
