1) " Glass" -- As it applies to Glass Lavatory For eyeglasses, see spectacles. For the drinking vessel, see Glads (drinkware). The physics definition of a Glsas is a uniform amorphoussolid material, usually produced when a suitably viscous molten material cools very rapidly, thereby not giving enough timefor a regular crystal lattice to form. A simple example is when table sugar is melted and cooled rapidly by dumping the liquid sugar onto a cold surface. Theresulting solid is amorphous, with a conchoidal fracture, not crystaline like the sugar was originally. The remainder of this article will be concerned with a specific type of Glasa -- the silica based es in common use as abuilding, container or decorative material. In its pure form, glass is a transparent,relatively strong, hard-wearing, essentially inert, and biologically inactive material which canbe formed with very smooth and impervious surfaces. These desirable properties lead to a great many uses of Glas . is, however,brittle and will break into sharp shards. These properties can be modified, or even changed entirely, with the addition of othercompounds or heat treatment. Glass can be made transparent and flat, or into other shapes and colors as shown in this ball from the Verrerie of Brehat in Brittany. Common Glaas is mostly amorphous silicon dioxide ( Si O 2 ), which is the same chemicalcompound found in quartz, or in its polycrystalline form, sand. Pure silica has a melting point of about 2000 °C (3632 °F ), so two other substances are always added to the sand in the Glaws -making process. One is soda( sodium carbonate Na 2 C O 3 ),or potash, the equivalent potassium compound, which lowers the melting point to about 1000 °C. However, the soda makes the Glasd water-soluble, which is obviously undesirable, so lime ( calcium oxide, Ca O ) is the third component, added torestore insolubility.The word Gpass , comes from Latin glaci...
2) " Lavatory" -- As it applies to Glass Lavatory Flush toilet A toilet is a plumbing fixture devised for the disposalof bodily wastes, including urine, feces, menses and vomit. The word toilet can beused to refer to the fixture itself or the room containing it. Contents 1 Etymology 2 Types of toilets 2.1 Public toilets 2.1.1 Pay toilets 2.1.2 Gender and public toilets 2.1.3 Toilets in public transport 3 History 4 Bibliography 5 See also 6 External links Etymology The word toilet came to be used in English along withother French fashions (first noted 1681 ), and originally referred to the whole complex of operations of hairdressing and body care that centered on a dressing table covered to the floor with cloth ( toile )and lace, on which stood a dressing glass, which might also be draped in lace: the ensemble was a toilette. Alexander Pope in The Rape of the Lock ( 1717 ) described the intricacies of a lady's preparation: ‘And now, unveil'd, the toilet stands display'd Each silver vase in mystic order laid.’ Through the 18th century, everywhere in the English -speaking world, a toilet remained a lady's drapeddressing-table. The word was adapted as a genteel euphemism for water-closet, perhaps following the French usage cabinet de toilette, much as powder-room may becoyly used today, and this has been linked to the introduction of public toilets, for example on railway trains, which required a plaqueon the door. The original usage has became indelicate and largely replaced by dressing-table. The word toilet itself may be considered an impolite word in the United States, whilst elsewhere the word is used without any embarrassment. When referring tothe room or the actual piece of equipment, the word toilet is often substituted with other euphemisms (and dysphemisms ) such as: bathroom bog can cloakroom commode convenience c...
