A method of fabricating a glass panel includes forming a non-chamfered glass panel by cutting a glass sheet. The non-chamfered glass panel is formed by cutting the glass sheet along a first sideline segment, cutting the glass sheet along a corner line segment set connected to the first sideline segment, and cutting the glass sheet along a second sideline segment connected to the corner line segment set. An extension of the first sideline segment and an extension of the second sideline segment intersect each other at a first interior angle narrower than 230?. The first sideline segment and the corner line segment set are connected at an interior angle wider than the first interior angle and 180? but narrower than 230?. The corner line segment set and the second sideline segment are connected at an interior angle wider than the first interior angle and 180? but narrower than 230?.

A method for manufacturing a glass light guide plate having high transmission efficiency is provided. A glass plate is cut and formed using a cutter machine. The glass plate includes a first flat surface and a second flat surface that are opposite and parallel to each other, and a light incident surface perpendicular and connected to the first flat surface and the second flat surface. The light incident surface is heated and extruded using a thermoplastic machine to deform the light incident surface to form a light guide portion. The light guide portion includes a light guide surface perpendicular to the first flat surface and the second flat surface, and has an area greater than an area of the light incident surface. When a light enters via the light guide surface, the amount of light irradiating corners of the light guide surface is reduced.

A pressing device for preparing culture dishes using flat glass and a process thereof, utilizing a flat glass bending molding process of high borosilicate glass or soda-lime glass. The prepared culture dish can not only give full play to the excellent physical and chemical properties of high borosilicate glass flat glass or soda-lime glass, but also the flatness of the inner plane of the glass bottom of the culture dish is higher, the product quality is stable, and it is more energy-saving, efficient and high-quality.
