Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
Carboy. A 25 L ( 61⁄2 US gal) glass carboy acting as a fermentation vessel for beer. It is fitted with a fermentation lock. A carboy, also known as a demijohn or a lady jeanne, is a rigid container with a typical capacity of 4 to 60 litres (1 to 16 US gal). [ 1][ 2] Carboys are primarily used for transporting liquids, often drinking water or ...
Motive: Vienna. A snow globe (also called a waterglobe, snowstorm, [1] or snowdome) is a transparent sphere, traditionally made of glass, enclosing a miniaturized scene of some sort, often together with a model of a town, neighborhood, landscape or figure. The sphere also encloses the water in the globe; the water serves as the medium through ...
The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, most writers claim that they may have been producing copies of glass objects from Egypt. [ 1] Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. [ 2]
A glass building facade. Glass is an amorphous ( non-crystalline) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass like "a glass" of water, "glasses", and "magnifying glass", are named ...
Cymatics. A demonstration of sand forming cymatic patterns on a metal plate. Cymatics (from Ancient Greek: κῦμα, romanized : kŷma, lit. 'wave') is a subset of modal vibrational phenomena. The term was coined by Swiss physician Hans Jenny (1904–1972). Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of ...
Like other mosaics, Byzantine mosaics are made of small pieces of glass, stone, ceramic, or other material, which are called tesserae. [18] During the Byzantine period, craftsmen expanded the materials that could be turned into tesserae, beginning to include gold leaf and precious stones, and perfected their construction.
In the case of dry sand, sand is so much denser than air that the buoyancy effect is commonly neglected (less than one part in one thousand). Mass change upon displacing one void material with another while maintaining constant volume can be used to estimate the void fraction, if the difference in density of the two voids materials is reliably ...
