Many manufacturers employ a process called constant density to tint the lenses. It is the oldest method of creating sunglasses and involves a glass or polycarbonate mixture with a uniform color throughout the material. The tint is built right into the lenses when they are created. Tinting can ...

The paper is then heated and pressed to fuse the image formed by the toner to the paper's surface. When the copier illuminates the sheet of paper on the glass surface of a copier, a pattern of the image is projected onto the positively charged photoreceptive drum below. Light reflected fr...
Scientists even built jars to hold this fluid and study its effects. The Dutch instrument makers Ewald von Kleist and Pieter van Musschenbroek created what is now known as a Leyden jar, a glass jar containing water and a nail that could store an electrical charge. The first time Musschenbroek...

Think of it as liquid glass that, once heated, forms an incredibly strong protective shell. The glazing process at Lenox is very interesting to watch. Let's take a closer look. Glazing Bone China Notice the glowing orange area to the right — this is where the dishes are pre-heated ...
Breaking glass has its own distinctive sound frequency (pattern of air-pressure fluctuations). The microphone converts this to an electrical current of that particular frequency, which it sends to the brain. On its way to the brain, the current passes through a crossover, an electrical device ...

To avoid electrical shock or accidents, ensure that the recessed lights are disconnected from the power source before starting. Be extra cautious when removing light fixtures and glass covers as they are fragile and can easily break, which can result in damage or injury. ...
Glass is made using two main techniques: the Float Glass Process, which involves floating molten glass on a bed of molten metal, and Glassblowing, which involves inflating molten glass into a bubble.
