Glazing, which derives from the Middle English for 'glass', is a part of a wall or window, made of glass. [ 1 ] [ 2 ] Glazing also describes the work done by a professional " glazier ". Glazing is also less commonly used to describe the insertion of ophthalmic lenses into an eyeglass frame.
Sometimes, drops of water crystallize on cold objects as rime instead of glaze. Soft rime has a density between a quarter and two thirds that of pure ice, [95] due to a high proportion of trapped air, which also makes soft rime appear white. Hard rime is denser, more transparent, and more likely to appear on ships and aircraft.
Rime ice also forms when ice forms on the surface of an aircraft, particularly on the leading edges and control surfaces when it flies through a cloud made of supercooled water liquid droplets. Rime ice is the least dense, milky ice is intermediately dense and clear ice is the most dense. All forms of ice can spoil lift and may have a ...
This form of ice is also called glaze. Rime ice is rough and opaque, formed by supercooled drops rapidly freezing on impact. Forming mostly along an airfoil's stagnation point, it generally conforms to the shape of the airfoil. Mixed ice is a combination of clear and rime ice, having both properties.
A similar phenomenon occurs when freezing rain or drizzle hits a surface and is called glaze. Clear ice, when formed on the ground, is often called black ice , and can be extremely hazardous. Clear ice is denser and more homogeneous than hard rime ; like rime, however, clear ice accumulates on branches and overhead lines, where it is ...
Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin, [1] although lead was used for the process in the past. [2] This method gives the sheet uniform thickness and a very flat surface. [ 3 ]
On unheated motor vehicles, the frost usually forms on the outside surface of the glass first. The glass surface influences the shape of crystals, so imperfections, scratches, or dust can modify the way ice nucleates. The patterns in window frost form a fractal with a fractal dimension greater than one, but less than two. This is a consequence ...
A type of rime consisting of opaque, granular masses of ice deposited primarily on vertical surfaces by freezing fog. Hard rime is more compact and amorphous than soft rime and usually develops on windward surfaces exposed to high wind speeds and air temperatures between −2 and −8 °C (28 and 18 °F). Harmattan haze
