Pestle
A mortar and pestle is a set of two simple tools used to prepare ingredients or substances by compression (physics), crushing and shear force, grinding them into a fine Paste (rheology), paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hardwood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, or rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since the Stone Age; today they are typically associated with the pharmacy profession due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making Grog (clay), grog; ...

Pesto
Pesto (), also known as ''pesto alla genovese'' () or ''pesto genovese'', is an Italian paste made with basil leaves, crushed garlic, pine nuts, olive oil, salt, and grated hard cheese such as Parmesan or '' pecorino sardo''. It originated in the Ligurian city of Genoa, and is used to dress pasta. Etymology The name pesto is the past participle of the Genoese verb (Italian: ), meaning 'to pound', 'to crush': the ingredients are "crushed" or ground in a marble mortar through a circular motion of a wooden pestle. The same Latin root is the basis for ''pestle''. There are other foods called ''pesto'', but ''pesto'' by itself usually means ''pesto alla genovese''. History Pesto is thought to have had two predecessors in ancient times, going back as far as the Roman age. The ancient Romans used to eat a similar paste called '' moretum'', which was made by crushing garlic, salt, cheese, herbs, olive oil, and vinegar (and sometimes pine nuts) together. The use of this past ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Age Stone Mortar & Pestle, Kebaran Culture, 22000-18000 BP
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...

Churning (butter)
Churning is the process of shaking up cream or whole milk to make butter, usually using a device called '' butter churn''. In Europe from the Middle Ages until the Industrial Revolution, a churn was usually as simple as a barrel with a plunger in it, moved by hand. These have mostly been replaced by mechanical churns. Butter is essentially the fat of milk. It is usually made from sweet cream (that is, cream skimmed from milk rather than whey). In the USA, Ireland, the UK and the Nordic countries, salt is usually added to it. Unsalted (sweet) butters are most commonly used in the rest of Europe. It can also be made from acidulated or bacteriologically soured cream. Well into the 19th century butter was still made from cream that had been allowed to stand and sour naturally. The cream was then skimmed from the top of the milk and poured into a wooden tub. Buttermaking was done by hand in butter churns. The natural souring process is a very sensitive one and infection by foreign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Butter Churn
A butter churn is a device used to convert cream into butter, a process known as churning. This is done through a mechanical process, frequently via a pole inserted through the lid of the churn, or via a crank used to turn a rotating device inside the churn. Etymology The word ''butter'' is believed by some to derive from the Greek word ''bou-tyron'', the approximate meaning of which is 'cow cheese'. Others believe it came from the Scythian culture, as the ancient Greeks tended to herd sheep and goats, whose milk is not as good for butter making as cow milk, which the Scythians primarily herded. The word ''churn'' is from the Old English ''ċyrin'' 'to churn'. This is probably derived from the Old English ''cyrnel'' 'kernel', due to the appearance of butter grains after milk has been churned. The butter churn gave its name and rough form to the milk churn, which is used to transport milk, not churn it. History The use of butter is mentioned in biblical works and the earl ...

Burr Mill
A burr grinder or like mistakenly called burr mill. —is a mill used to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. When the two surfaces are set far apart, the resulting ground material is coarser, and when the two surfaces are set closer together, the resulting ground material is finer and smaller. Often, the device includes a revolving screw that pushes the food through. It may be powered electrically or manually. Burr mills do not heat the ground product by friction as much as blade grinders ("choppers"), and produce particles of a uniform size determined by the separation between the grinding surfaces. Food burr mills are typically designed for a specific purpose, such as grinding coffee beans, dried peppercorns, coarse salt, various spices, or poppy seeds as an example. Coffee mills for volume consumption are usually powered by electric motors, but fast and precise manual mills have experience ...

Blender
A blender (sometimes called a mixer (from Latin ''mixus, the PPP of miscere eng. to Mix)'' or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances. A stationary blender consists of a blender container with a rotating metal or plastic blade at the bottom, powered by an electric motor that is in the base. Some powerful models can also crush ice and other frozen foods. The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container. Characteristics Different blenders have different functions and features but product testing indicates that many blenders, even the less expensive ones, are useful for meeting many consumer needs. Features which consumers consider when purchasing a blender include the following: *large visible measurement marks *ease of use *low noise during usage *power usage (typically 300–1000 ...

Ergonomics
Ergonomics, also known as human factors or human factors engineering (HFE), is the application of Psychology, psychological and Physiology, physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error, increase productivity and system availability, and enhance safety, health and comfort with a specific focus on the interaction between the human and equipment. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to previously stated goals. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its Cog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Of Gravity
In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, a mutual attraction between all massive particles. On Earth, gravity takes a slightly different meaning: the observed force between objects and the Earth. This force is dominated by the combined gravitational interactions of particles but also includes effect of the Earth's rotation. Gravity gives weight to physical objects and is essential to understanding the mechanisms responsible for surface water waves and lunar tides. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. The gravitational attraction between primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars. At larger scales this results in galaxies and cluster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallet
A mallet is a tool used for imparting force on another object, often made of rubber or sometimes wood, that is smaller than a maul or beetle, and usually has a relatively large head. General overview The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel. Mallets are used in various industries, such as upholstery work, and a variety of other general purposes. It is a tool of preference for wood workers using chisels with plastic, metal, or wooden handles, as they give a softened strike with a positive drive. * Wooden mallets are usually used in carpentry to knock wooden pieces together, or to drive dowels, chisels and to apply pressure on joints. A wooden mallet will not deform the striking end of a metal tool, as most metal hammers would. It is also used to reduce the force driving the cutting edge of a chisel, giving better control.
