Minute metal beads, usually, used to decorate jewelry. See ETRUSCAN.
tiny particle of metal heat-fused to a metal surface without the use of solder.
An ancient jewellery art, perfected by the Etruscans, by which small gold particles adhere to a gold surface without evidence of solder.
Tiny convective cell structures visible in white light ("rice grains"), best seen in apertures over three inches, and in green light. Each cell consists of a brighter polygonal area of hot rising gas typically about 1100 km across, and a cooler edge or "channel" of descending gas about 230 km wide.
diminutive of Latin granum = a grain.
A special solderless technique for adhering gold beads to a surface.
The application of minute granules or grains of metal to the surface of a piece of jewelry to form a decorative pattern; often used in Etruscan Revival jewelry.
Mottled appearance of the solar surface, caused by rising (hot) and falling (cool) material in convective cells just below the photosphere.
Appearance on the Sun's photosphere of roughly circular regions on the Sun whose bright centers indicate hot gases rising to the surface, and whose dark edges indicate cooled gases that are descending towards the interior. Individual granules appear and disappear on time scales of about 5 minutes and are typically about 1000 km.
the act of forming something into granules or grains; "the granulation of medicines"
The "grains of rice" appearance of the Sun's surface, which results from convection cells within the Sun.
One of the oldest jewelry design techniques, dating to 2500 BC. Tiny grains of gold or other metal are stuck to a surface as ornaments
The production of coarse metal particles by pouring the molten metal through a screen into water (shotting) or by violent agitation of the molten metal while solidifying. Not to be confused with Granulation as used in pharmaceutical terminology.
A process of fusing granules (typically small spheres) to a piece. No solder is used in granulation. Granulation works best with pure metals (i.e. fine silver or very high karat gold). This is an ancient technique covered in more detail on Molly Greece's site.
A mottled cellular pattern visible on the Sun's photosphere. It is caused by the convective motion of hot gas rising from the Sun's interior.
The mottled, orange peel, appearance of the Sun's surface; caused by convection within the Sun.
Granulation: The process of forming granules (small grains or particles) from a chemical.
in metalwork, the soldering of globules of gold or silver onto jewellery
Cellular structure of the solar photosphere visible at high spatial resolution.
decorative technique using minute spheres of metal (usually gold) applied to a same-metal surface without using solder (eutectic bonding). Mock granulation uses solder to achieve a similar effect
The rice-grain-like structure of the solar photosphere; granulation is produced by upwelling currents of gas that are slightly hotter, and therefore brighter, than the surrounding regions, which are flowing downward into the Sun.
Series of tiny round decorations applied in a line.
A net - like pattern of irregular cells on the solar surface, visible in white light. The cells are caused by plasma convection within the photosphere. Cell diameters are 800 km (450 naut. mi.) to 3000 km (1700 naut. mi.); each individual cell has a lifetime of several minutes.
The fine structure visible on the solar surface caused by rising currents of hot gas and sinking currents of cool gas below the surface.
A technique often used in Etruscan Revival jewelry, granulation is the application of minute granules or grains of metal to the surface of a piece of jewelry to form a decorative pattern.
The cellular structure of the photosphere. "Granules" are formed by convection, each one is quite large, about 700 to 1000 km (400 - 600 miles) in diameter.
Small metal balls or wires are arranged on a metal sheet, then the piece is very carefully heated until the metals fuse together. Care must be taken to heat the larger base piece enough to fuse, but avoid heating the small pieces so much that they melt before fusion takes place
It is the process of texturing of a surface by the application of tiny balls (grains) of gold or silver.
A pattern of small cells seen on the surface of the Sun caused by the convective motions of the hot solar gas.
bright spots of convection on the Sun's surface 700 to 1000 kilometers across forming a honeycomb pattern. Formed from hot, bright gas rising from below in the center of a granule and cooler, dimmer gas falling back down at the edge of a granule.
a metalsmithing technique using tiny spheres of silver and attaching them to a silver base in complex designs. Most commonly seen in Balinese metalwork. One of my favorite types of beads
Refers to powder grain size and type. Can apply to either black or smokeless powder.
In close up, the surface of the Sun appears to be mottled. This mottling of the surface is called granulation. It is thought to be caused by convection currents in the Sun.
