Sand glass, also known as hourglass, is made by combining two glass bulbs connected by a narrow neck with sand flowing between them. The process involves melting glass into bulb shapes, connecting them with the neck, and filling one bulb with sand. The sand flows through the neck at a controlled rate, measuring time as it moves from one bulb to the other.
