A modern greenhouse in Wisley Garden, England, made from float glass

Flat glass for windows and similar applications is formed by the float glass process, developed between 1953 and 1957 by Sir Alastair Pilkington and Kenneth Bickerstaff of the UK's Pilkington Brothers, who created a continuous ribbon of glass using a molten tin bath on which the molten glass flows unhindered under the influence of gravity.

Modern glass intended for windows is produced as float glass and is very uniform in thickness.

Common soda-lime float glass appears green in thick sections because of Fe < sup > 2 +</ sup > impurities.

An aluminium glass mirror is made of a float glass manufactured using vacuum coating, i. e. aluminium powder is evaporated ( or " sputtered ") onto the exposed surface of the glass in a vacuum chamber and then coated with two or more layers of waterproof protective paint.

This kind of glass mirror is produced by coating a silver, copper film and two or more layers of waterproof paint on the back surface of float glass, which perfectly resists acid and moisture.

Windows are usually glazed or covered in some other transparent or translucent material like float glass.

The new float glass, produced in a continuous process, replaced the production of plate glass, which had been produced in batches.

The variable area ( VA ) meter, also commonly called a rotameter, consists of a tapered tube, typically made of glass, with a float inside that is pushed up by fluid flow and pulled down by gravity.

* Iced latte is often served unstirred so that coffee appears to " float " on top of white milk in a glass cup.

Modern windows are made from float glass.

Most float glass is soda-lime glass, but relatively minor quantities of specialty borosilicate and flat panel display glass are also produced using the float glass process.

The washing process whereby soils are removed consists basically of applying mechanical action to loosen the dirt particles and dried matter in the presence of water which helps to float off the debris and acts, to some extent, as a dissolving and solvating agent.

The starch grains that float to the surface during the soaking process are also used in cooking.

Flotation is a process of retrieval that works by passing spoil onto the surface of water and separating finds that float from the spoil which sinks, this is especially suited to the recovery of environmental data such as seeds and small bones.

This process is also known as the float zone process, particularly in semiconductor materials processing.

Some sceptics asserted the promoters were merely using silver from somewhere else, to ramp up the shares ... Another shareholder, the dominating W. R.

The nuts can only float after the germination process, when they are hollow.

Before the development of float glass, larger sheets of plate glass were made by casting a large puddle of glass on an iron surface, and then polishing both sides, a costly process.

This process continued in use for many years after the development of float glass.

Tin is suitable for the float glass process because it has a high specific gravity, is cohesive, and immiscible into the molten glass.

* Pilkington Brothers patent the float glass process invented by Alastair Pilkington.

At the same time, the historic plate process for making flat glass is becoming obsolete with the adoption of the much more efficient float process.

( Sir Alastair Pilkington ) and his associate Kenneth Bickerstaff, both of Great Britain, developed the world's first commercially successful manufacture of high quality flat glass using their float glass process.

Starting in the early 1960s, all the world's leading flat glass manufacturers obtained licences to use the float glass process.

Baker further improved the process with the float shoe in 1923.

During the casting process various methods are used, such as addition of aluminum, so that impurities in the steel float to the surface where they can be cut off the finished bloom.

Ambergris is less dense than water and floats, whereas amber is less dense than stone, but too dense to float.

The pipe from the straight tube is connected to the top of the sealed chamber and the pipe from the small tubes is directed into the bottom inside the float.

Since the pressure difference determines the vertical position of the float this is a measured of the wind speed.

A boat is a watercraft of any size designed to float or plane, to provide passage across water.

These include boat lifts, such as the Falkirk wheel, which use a caisson of water in which boats float while being moved between two levels ; and inclined planes where a caisson is hauled up a steep railway.

If the average density ( including any air below the waterline ) of an object is less than water it will float in water and if it is more than water's it will sink in water.

Contrast with a record, which could be defined to contain a float and an integer ; whereas, in a union, there is only one value at a time.

There also exist planetary-mass objects that orbit brown dwarfs and other bodies that " float free " in space not bound to any star ; however, the term " planet " is not always applied to these objects.

The term floating point refers to the fact that the radix point ( decimal point, or, more commonly in computers, binary point ) can " float "; that is, it can be placed anywhere relative to the significant digits of the number.

One common game is dunking or apple bobbing, which may be called " dooking " in Scotland in which apples float in a tub or a large basin of water and the participants must use their teeth to remove an apple from the basin.

Whenever the solution is depleted below a certain level, either water or fresh nutrient solution is added, A Mariotte's bottle, or a float valve, can be used to automatically maintain the solution level.

If not contained, it can float if flood and drain feeding is used.

Some insurance industry insiders, most notably Hank Greenberg, do not believe that it is forever possible to sustain a profit from float without an underwriting profit as well, but this opinion is not universally held.
