What is the most excellent among methods of manufacturing plate glass, which has been developed so far, is float process. This is a method of making plate glass by filling the melted tartar in a kiln called as tin bath, and allowing the glass water in a liquefied state to flow over it horizontally. Hanlite, which is produced with this global technique, is the high-quality perfect glass that satisfies all conditions requested by modern architecture.
It is excellent in the surface glossing, is clean and transparent like crystal.
Thickness is consistent, and there is no winding on the surface, thereby being not shown the distortion on the look.
Owing to producing large back glass, the width in option is broad.
Quality is very excellent, thereby being used as the disk in several kinds of the processing glass.
