Flint is a simple tool for managing and analysing your personal information. The tool is very light weight and is easy to install and use.
A massive, somewhat impure variety of quartz, in color usually of a gray to brown or nearly black, breaking with a conchoidal fracture and sharp edge. It is very hard, and strikes fire with steel.
Anything extremely hard, unimpressible, and unyielding, like flint.
Fine grain verity of Quartz, usually characterized by its darker color gray, red, black, and sometimes even white. commonly found as layers in limestone.
A dense, fine-grained, naturally occurring form of silica (Si02) that fractures conchoidally. A variety of chert, the more technical term. Most flint is gray, brown, black, or otherwise dark, but nodules and other chunks tend to weather white or change to lighter shades from the surface inward.
A dense, black to dark gray variety of chert.
Stone that sparks when struck against iron
Nodules of stone found in layers in chalk deposits, extracted by digging or mining. Flint can be worked by splitting into shards, then shaped using percussion or pressure flaking.
Fine grained, hard silica-based stone, which has sharp edges when broken and which produces sparks when hit with steel.
Sometimes used as a synonym for chert.
A maize ( Zea mays indurata) having usually rounded kernels with a hard outer layer.
a material used for producing a spark (can be of hard quartz) Mississippi: A Site for All Seasons
A microcrystaline silicate rock similar to CHERT, used for the manufacture of flaked stone tools. Colour . most commonly grey, honey-brown, or black.
a hard, fine-grained type of quartz that when struck by steel, produces sparks to start fires
a hard stone or, as if to bind firmly, or pressed hard according to the Hebrew word Tsor
a type of stone that is usually cut into a tiny cylindrical shape
a hard quartz mineral that arrow heads were carved from Go back
Flint is siliceous microcrystalline and found in chalk
A hard glassy rock which flakes easily and can be worked to produce a sharp cutting edge. Used in prehistoric times for the manufacture of tools and weapons such as scrapers and arrowheads
(2) -- a kind of hard stone, most commonly of a steely gray color, found in roundish nodules of varying size, usually covered with a white incrustation (Oxford Dict.)
hard fine-grained quartz that sparks when struck with steel
a hard kind of stone; a form of silica
SiO. Cryptocrystalline native silica. Almost pure silica containing less than 5% impurity in the form of calcium carbonate. In bodies it gives a whiteness, hardness and a resistance to crazing. In glazes it provides extra silica when needed and is often used to balance the silica amount when adjustments are made for purposes of glaze fit.
a form of chert (silica, SiO2) found in chalk deposits, flint is a chemical sedimentary rock that forms from the remains of silica-bodied organisms.
An abrasive made from the natural mineral high in silicates. With a hardness much less than garnet or aluminumm oxide, flint has no applications in metalworking and only a few in woodworking for the companies that still use old finishing techniques.
An extremely tough stone widely used in British buildings, especially in areas of the South East and East Anglia. The Georgians often used it in conjunction with brick or stone to add decorative interest, extra strength and stability, but it has actually been used as a building material since well before the Roman times.
A hard, brittle stone, usually a type of chalk or limestone that can be flaked (see below) in any direction and easily shaped. Flint occurs naturally in many locations and often formed the material for human tools, until humans learned to work metals. Flint was the most common 'stone' of the Stone Age.
a very fine-grained siliceous rock.
Calcined and powdered silica. Used in earthenware bodies.
Main source of silica in glazes; increases their viscosity and hardness.
Microcrystalline quartz (SiO2) found in chalk. Chert is the equivalent in any other rock, i.e. flint is chert.
Flint (or flintstone) is a hard, sedimentary cryptocrystalline silicate form of the mineral quartz, categorized as a variety of chalcedony. Flint is usually dark-grey, blue, black, or deep brown in colour, and often has a glassy appearance. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.
Flint tools were made by stone age peoples worldwide. Paleolithic tools were relatively simple, repeated small flakes being struck or pressed from a flint until the required shape was achieved. By Neolithic times in Europe the manufacture of flint and obsidian blades had become a highly skilled industry (see Tool stone).
