Spider Wasp, Mansfield CT

$19.00$400.00

Wasps in the family Pompilidae are commonly called spider wasps or pompilid wasps.[1]The family is cosmopolitan, with some 5,000 species in six subfamilies.[2] All species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are cleptoparasites of other pompilids, or ectoparasitoids of living spiders.[3]

In South America, species may be referred to colloquially as marabunta or marimbondo, though these names can be generally applied to any very large stinging wasps. Furthermore, in some parts of Venezuela and Colombia, it is called matacaballos, or “horse killers”, while in Brazil some particular bigger and brighter species of the general marimbondo kind might be called fecha-goela, or “throat locker”.

Eyeliner

$19.00$400.00

Eye liner was first used in Ancient Egypt and Mesopotamia as a dark black line around the eyes. As early as 10,000 BC, Egyptians and Mo wore various cosmetics including eye liner not only for aesthetics but to protect the skin from the desert sun. Research has also speculated that eye liner was worn to protect the wearer from the evil eye. The characteristic of having heavily lined eyes has been frequently depicted in ancient Egyptian art. They produced eye liner with a variety of materials, including copper ore and antimony. Ancient Egyptian kohl contained galena, which was imported from nearby regions in the Land of Punt, Coptos and Western Asia.[1]

In the 1920s, Tutankhamun‘s tomb was discovered, introducing the use of eye liner to the Western world. The 1920s were an era commonly associated with many changes in women’s fashion, and women felt freer to apply make-up more liberally.

In the 1960s, liquid eye liner was used to create thick black and white lines around the eyes in the make-up fashion associated with designers like Mary Quant.

No. 2 Pencil

$19.00$400.00

Many pencils across the world, and almost all in Europe, are graded on the European system using a continuum from H (commonly interpreted as “hardness”) to B (commonly “blackness”), as well as F (usually taken to mean “fineness”, although F pencils are no more fine or more easily sharpened than any other grade. also known as “firm” in Japan[45]). The standard writing pencil is graded HB.[46]

According to Petroski, this system might have been developed in the early 20th century by Brookman, an English pencil maker. It used B for black and H for hard; a pencil’s grade was described by a sequence or successive Hs or Bs such as BB and BBB for successively softer leads, and HH and HHH for successively harder ones.[47]

The Koh-i-Noor Hardtmuth pencil manufacturers claim to have originated the HB standard of gradations, with H standing for Hardtmuth, B for the company’s location of Budějovice, and F for Franz Hardtmuth, who was responsible for technological improvements in pencil manufacture.[48][49]

Very large collections are conserved in natural history museums or universitieswhere they are maintained and studied by specialists. Many college courses require students to form small collections.

Flashlight Lens

$19.00$400.00

A flashlight (more often called a torch outside North America) is a portable hand-held electric light. The source of the light is usually an incandescent light bulb or light-emitting diode (LED). A typical flashlight consists of a light bulb mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch. These are supported and protected by a case.

The invention of the dry cell and miniature incandescent electric light bulbs made the first battery-powered flashlights possible around 1899. Today flashlights use mostly incandescent lamps or light-emitting diodes and run on disposable or rechargeable batteries. Some are powered by the user turning a crank or shaking the lamp, and some have solar panels to recharge a battery.
