Abstract: A foldable glass substrate includes a top surface, a bottom surface, and a side surface. The side surface includes a first side surface extending at a first angle from the top surface, a second side surface extending at a second angle from the bottom surface, and a third side surface extending from each of the first side surface and the second side surface. A length of the third side surface in a direction substantially perpendicular to at least one of the top surface and the bottom surface is equal to or greater than about 0.3 times and equal to or less than about 0.7 times of a minimum distance between the top surface and the bottom surface. The minimum distance is equal to or greater than about 15 micrometers (μm) and equal to or less than about 100 μm.

Abstract: A method of manufacturing a window and a window manufactured by the same are provided. A method of manufacturing a window includes laser cutting a base glass into a preliminary window using first laser light, irradiating, with second laser light, a point spaced apart from an edge of the preliminary window at a first distance, and providing a window including a flat portion and an edge portion by wet etching the preliminary window irradiated with the second laser light. A method of manufacturing a window having a chamfer shape at the edge portion is facilitated.

Abstract: A refill system includes a tempering furnace, a refill furnace which stores the molten potassium nitrate obtained by melting powdered potassium nitrate, a supply unit which supplies the molten potassium nitrate to the tempering furnace, a tempering furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the tempering furnace, a refill furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the refill furnace, and a central control unit which checks the load amount of the molten potassium nitrate in the tempering furnace and the refill furnace in real time, and controls the supply unit to stop supplying the molten potassium nitrate to the tempering furnace when the load amount of the molten potassium nitrate in the tempering furnace is greater than or equal to a predetermined load amount.
