seahorse swimming beside float glass

oat glass is made by melting glass and feeding a thin layer onto a tank of molten tin in a nitrogen atmosphere. The glass flattens out forming a perfectly smooth glossy surface on both sides with an even thickness. This allows the production of smooth clear window glass very economically.As the glass flows down a long narrow tunnel, the temperature is gradually reduced until the sheet can be lifted from the tin onto rollers, where it is further cooled gradually so that it anneals without strain and doesn't crack from the change in temperature.The nitrogen keeps the tin from oxidizing. Some tin is absorbed into the glass, and with a proper ultraviolet light a sheen can be seen which differentiates the tin from the non-tin side. See more at Wikipedia.org...

>This article is about the fish; for other meanings of seahorse, see Seahorse (disambiguation). See text. Hippocampus is a genus of fish known as Seahorses (family Syngnathidae). They are found in temperate and tropical waters all over the world. Seahorses (which are not true horses) range in size from 16 mm (the recently discovered Hippocampus denise [1]) to 35 cm. They are notable for being one of only a few species where the males get pregnant. A seahorse pregnancy lasts approximately two to three weeks. Seahorses are also unusual among fishes for being monogamous. See more at Wikipedia.org...
