Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking.
Egg decorating is the art or craft of decorating eggs. It has been a popular art form throughout history because of the attractive, smooth, oval shape of the egg, and the ancient associations with eggs as a religious and cultural symbol. Egg decorating has been associated with Easter in recent times, but was practiced independently by many ancient cultures.
A backpack—also called knapsack, rucksack, pack, booksack, bookbag, haversack or backsack—is, in its simplest frameless form, a fabric sack carried on one's back and secured with two straps that go over the shoulders, but it can have an external frame, internal frame, and there are bodypacks.
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware.
A stopper, bung, or cork is a cylindrical or conical closure used to seal a container, such as a bottle, tube, or barrel.
A mess kit is a collection of silverware and cookware designed for use by military personnel for food and military rations. They may also be used during camping and backpacking. There are many varieties of mess kits that militaries issue to their personnel that later become available to consumers.
A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.
Induction cooking is performed using direct electrical induction heating of cooking vessels, rather than relying on indirect radiation, convection, or thermal conduction. Induction cooking allows high power and very rapid increases in temperature to be achieved: changes in heat settings are instantaneous.
A water bottle is a container that is used to hold liquids, mainly water, for the purpose of transporting a drink while travelling or while otherwise away from a supply of potable water.
Blombos Cave is an archaeological site located in Blombos Private Nature Reserve, about 300 km east of Cape Town on the Southern Cape coastline, South Africa. The cave contains Middle Stone Age (MSA) deposits currently dated at between c. 100,000 and 70,000 years Before Present (BP), and a Late Stone Age sequence dated at between 2000 and 300 years BP. The cave site was first excavated in 1991 and field work has been conducted there on a regular basis since 1997, and is ongoing.
Intermediate bulk containers are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, semi-solids, pastes, or solids. The two main categories of IBC tanks are flexible IBCs and rigid IBCs. Many IBCs are reused or repurposed.
Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object by electromagnetic induction, through heat generated in the object by eddy currents.
The Klasies River Caves are a series of caves located east of the Klasies River Mouth on the Tsitsikamma coast in the Humansdorp district of Eastern Cape Province, South Africa. The Klasies River Main (KRM) site consists of 3 main caves and 2 shelters located within a cliff on the southern coast of the Eastern Cape. The site provides evidence for developments in stone tool technology, evolution of modern human anatomy and behavior, and changes in paleoecology and climate in Southern Africa based on evidence from plant remains.
The M-1956 Load-Carrying Equipment (LCE), also known as the Individual Load-Carrying Equipment (ILCE), was developed by the U.S. Army and first issued in the early 1960s. The M-1956 LCE was designed to replace the M-1945 Combat Pack, the M-1923 cartridge belt, the M-1936 pistol belt and the M-1937 BAR magazine belt. The M-1956 LCE was designed to be quickly configured, using no tools, to accommodate various mission and ammunition loads. The M-1956 LCE remained in service through the 1980s and set the standard for future United States military load-carrying equipment.
Sigg Switzerland AG is a Swiss manufacturing company with its headquarters in Frauenfeld. Sigg bottles are bottles designed and manufactured in Switzerland from aluminum and polypropylene or in China from stainless steel and glass. The company is famous because of the iconic shape its classic bottle and numerous designs which have led to its addition to the permanent design collection of the New York Museum of Modern Art.
The oldest undisputed examples of figurative art are known from Europe and from Sulawesi, Indonesia, dated about 35,000 years old . Together with religion and other cultural universals of contemporary human societies, the emergence of figurative art is a necessary attribute of full behavioral modernity.
Howiesons Poort is a technological and cultural period characterized by material evidence with shared design features found in South Africa, Lesotho, and Namibia. It was named after the Howieson's Poort Shelter archaeological site near Grahamstown in South Africa, where the first assemblage of these tools was discovered. Howiesons Poort is believed, based on chronological comparisons between many sites, to have started around 64.8 thousand years ago and ended around 59.5 thousand years ago. It is considered to be a technocomplex, or a cultural period in archaeology classified by distinct and specific technological materials. Howiesons Poort is notable for its relatively complex tools, technological innovations, and cultural objects evidencing symbolic expression. One site in particular, Sibudu Cave, provides one of the key reference sequences for Howiesons Poort. Howiesons Poort assemblages are primarily found at sites south of the Limpopo River.
Howieson's Poort Shelter is a small rock shelter in South Africa containing the archaeological site from which the Howiesons Poort period in the Middle Stone Age gets its name. This period lasted around 5,000 years, between roughly 65,800 BP and 59,500 BP. This period is important as it, together with the Stillbay period 7,000 years earlier, provides the first evidence of human symbolism and technological skills that were later to appear in the Upper Paleolithic.
Diepkloof Rock Shelter is a rock shelter in Western Cape, South Africa in which has been found some of the earliest evidence of the human use of symbols, in the form of patterns engraved upon ostrich eggshell water containers. These date around 60,000 years ago.
Package handles, or carriers, are used to help people use packaging. They are designed to simplify and to improve the ergonomics of lifting and carrying packages. Handles on consumer packages add convenience and help facilitate use and pouring. The effect of handles on package material costs and the packaging line efficiencies are also critical. A handle can be defined as “an accessory attached to a container or part for the purpose of holding or carrying.” Sometimes a handle can be used to hang a package for dispensing or use.
