Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Most bioactive glasses are silicate-based glasses that are degradable in body fluids and can act as a vehicle for delivering ions beneficial for healing. Bioactive glass is differentiated from other synthetic bone grafting biomaterials (e.g., hydroxyapatite , biphasic calcium phosphate, calcium sulfate), in that it is the only one with anti ...

What you need to know to keep your cooktop in the best shape.
The Bible has many rituals of purification in areas ranging from the mundane private rituals of personal hygiene and toilet etiquette to the complex public rituals of social etiquette. [3] Certain Christian rules of purity have implications for bodily hygiene and observing cleanliness, [4] including sexual hygiene, [5] menstruation and toilet ...
Also unlike toughened glass, chemically strengthened glass may be cut after strengthening, but loses its added strength within approximately 20 mm of the cut. Similarly, when the surface of chemically strengthened glass is deeply scratched, this area loses its additional strength. Another negative of chemically strengthened glass is the added cost.
By lamp, this verse may mean that the eye is a metaphorical window by which light enters the body. Alternatively the lamp might not be meant as a source of light, but rather as a guide through darkness, just as the eye is a guide through life. In this case the verse is almost certainly speaking of a spiritual eye rather than the literal organ.
