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.
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 ...

The World English Bible translates the passage as: “The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light.
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 ...
In this verse Jesus presents the example of the lilies, who also do no labour. Spin in this verse is a reference to spinning thread, a labour-intensive but necessary part of making clothing. Spinning was traditionally women's work, something made explicit in Luke's version of this verse.

Corelle, a brand name for break-resistant glass dishware also originally created by Corning Glass Works, has offered matching designs to many CorningWare patterns. [6] Care must be made to distinguish between Corning Ware cookware and tableware marketed under the Corelle and Pyrex brand names, as the thermal properties of the products are quite ...
