		The purple-blue of cobalt, the chrome green or yellow of chromium, the dichroic canarycolour of uranium and the violet of manganese, are constant.
		In an American process the glass is drawn direct from the molten mass in the tank in a cylindrical form by means of an iron ring previously immersed in the glass, and is kept in shape by means of special devices for cooling it rapidly as it leaves the molten bath.
		Glass, in flat pieces, such as might be employed for windows, has been found in the ruins of Roman houses, both in England and in Italy, and in the house of the faun at Pompeii a small pane in a bronze frame remains.

	GLASS IN THE PAST By Gordon Bock
		Though crown glass was made up to the 1850s, it could not supply the need for bigger panes created by a growing population.
		The glass that could was cylinder glass (also called broad glass or sheet glass), and it dominated this industry for the rest of the century.
		When cutting glass for window repairs, the point to remember is that cylinder glass has a smooth side, once the outside of the cylinder, and a rough side, the former inside.

	Crown glass (window) - Wikipedia, the free encyclopedia
		Due to the distribution of the best glass, in order to fill large window spaces many small diamond shapes would be cut from the edge of the disk and these would be mounted into a lead lattice work and fitted in the window.
		Crown glass was one of the two most common processes for making glass for windows up until the 19th century, the other was blown plate.
		Crown glass is one of many types of hand-blown glass.

	Is glass liquid or solid?
		It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom.
		Glass can be made from pure silica, but fused silica has a high glass transition point at around 1200° C which makes it difficult to mould into panes or bottles.
		Glass such as Pyrex (used for test-tubes and ovenware) is usually based on boro-silicates or alumino-silicates, which withstand heating better and typically have a higher glass transition temperature.

	The London Crown Glass Company - Types of window glass and how to choose.
		Cylinder glass marked NR (no ream) is the most suitable for window sashes of the late 17th century up to early twentieth century.
		Cylinder glass marked LR (low ream) is generally reserved for 16th century or earlier windows in lower grade housing or stables and for leaded lights.
		This is similar to Cylinder Blown Sheet Type NR but during the final process, the glass is slightly curved to give the bulging appearance of Crown glass.

		Two basic colours were made, the first using Flint (clear) glass which was sprayed at the glory hole to produce a wide range of marigold colours from pale pastels to a deep, rich, golden hue.
		With regard to the technical difference between the iridescent finish of carnival glass and the later luster finishes, the former was achieved by exposing the glass while hot and held on the punty, reheated at the glory hole and then sprayed with metallic compound, often of a toxic nature.
		The later luster finishes were achieved with metallic resinates applied to the cold glass by spraying or brushing and afterwards firing at a lower temperature than the previous method.
