Large electrostatic generator (Teylers). The large electrostatic generator (Dutch: Van Marum electriseermachine) is a large handcrafted electromechanical instrument designed by Martin van Marum and built by John Cuthbertson in 1784 for the Teylers Museum in Haarlem, where it forms the centerpiece of the instrument room. The concept of an electrostatic generator was new, and the battery (array) of leiden jars was the largest ever built (only one of the 4 sets of leiden jars is on display to conserve space). The two glass disks of the triboelectric generator (friction generator) are 1.65 meters in diameter, and the machine is capable of generating a potential of 330,000 volts.

History

The device is a larger version of a similar model built in Groningen by Gerhard Kuyper in 1774 for physics student Martin van Marum, who used it to make a name for himself in the study of electricity with his lectures and demonstrations.

It was Van Marum's dream to create a larger version, and he applied to the Teylers Stichting in 1783 for funding to create such a large instrument in the hope that it would add a valuable contribution to the science of electricity. On April 11 of that year his request was granted, and on May 7 Cuthbertson was employed who finished the device a year later and it was proudly installed on Christmas Eve. The machine performed above expectations and was only modified a few times to prevent leaks of the static charge. The study of electricity leakage led to many insights in the study of electricity. The machine was last modified in 1791. For the friction, cushions were used as an improvement over the mercury bath used in the earlier model. For a complete description of the electrostatic generator, an explanation was produced in 1868 by the Parisian author Adolphe Ganot (1804–1887).

Van Marum himself became curator of the physics cabinet at Teylers in the same year the instrument was ordered to be made. He used it again and again in laboratory lectures to the public and continued to make excursions with his smaller model, which he finally sold to the museum for 120 guilders in 1790.

Bultfonteinite. Bultfonteinite, originally dutoitspanite, is a pink, light-brown or colorless mineral with chemical formula Ca2SiO2(OH,F)4. It was discovered in 1903 or 1904 in the Bultfontein mine in South Africa, for which the mineral is named, and described in 1932.

Description

Bultfonteinite is transparent and ranges from pale pink or light brown to colorless. The mineral occurs as radiating prismatic acicular crystals and radial spherules up to .

Structure
The crystal structure of bultfonteinite consists of strips of [Ca4Si2O4]8+, that run along the 5.67 Å c-axis, held together by Ca–O–Ca, Ca–F–Ca, Ca–H2O–Ca, and Ca–O–Si bonds. Silicon atoms occur in isolated tetrahedra and the calcium atoms have seven-fold coordination, derived from a triangular prism with a seventh atom present on one of the square faces.

History
In either 1903 or 1904, a miner discovered the first specimen of bultfonteinite on the 480-foot level of the Bultfontein mine in Kimberley, South Africa. The mineral occurred in a several-hundred-foot-tall horse of kimberlite-enclosed dolerite and shale fragments. The specimen, mistakenly thought to be natrolite, was given to Alpheus F. Williams. Several years later, additional samples were found by C. E. Adams in the nearby Dutoitspan mine and given to the MacGregor Museum in Kimberley. Shortly before 1932, the mineral was found about  to the southeast of Kimberley at the Jagersfontein Mine in Orange River Colony.

After John Parry and F. E. Wright described the mineral afwillite in 1925, Williams recognized that his samples of bultfonteinite were not natrolite, but were likely a new mineral species. Chemical analysis by John Parry and crystallographic and optical determination by Wright proved it to be a new mineral. The mineral was described by Parry, Williams, and Wright in 1932 and named bultfonteinite. Their original description does not explicitly state the origin of the name, but it is presumably named after the mine in which it was discovered. Earlier that year in his book The Genesis of the Diamond, Williams had called the mineral dutoitspanite, a name which was "apparently discarded". When the International Mineralogical Association was founded, bultfonteinite was grandfathered as a valid mineral species.

The type material is held in England at Cambridge University and the Natural History Museum in London.

Occurrence
Bultfonteinite has been found in Australia, Botswana, Canada, Israel, Japan, Jordan, Russia, South Africa, and the United States. The mineral was first located outside South Africa in the US state of California in 1955. Bultfonteinite has been found in association with afwillite, apophyllite, calcite, natrolite, oyelite, scawtite, and xonotlite.

At the type locality, the mineral occurred in a large structure of dolerite and shale fragments in a kimberlite pipe. In Crestmore, California, bultfonteinite formed in the contact zone of thermally metamorphosed limestone.

Diphenyl sulfone. Diphenyl sulfone is an organosulfur compound with the formula (C6H5)2SO2. It is a white solid that is soluble in organic solvents. It is used as a high temperature solvent.  Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solvents.

It is produced by the sulfonation of benzene with sulfuric acid and oleum.  For typical processes, benzenesulfonic acid is an intermediate. It is also produced from benzenesulfonyl chloride and benzene.

Serandite. Serandite is a mineral with formula Na(Mn2+,Ca)2Si3O8(OH). The mineral was discovered in Guinea in 1931 and named for J. M. Sérand. Serandite is generally red, brown, black or colorless. The correct name lacks an accent.

Description
Serandite is transparent to translucent and is normally salmon-pink, light pink, rose-red, orange, brown, black, or colorless; in thin section, it is colorless. Octahedrally bonded Mn(II) is the primary contributor to the mineral's pink colors.

Crystals of the mineral can be prismatic to acicular and elongated along [010], bladed, blocky, or tabular and flattened on {100}, occur as a radiating aggregate, or have massive habit. Sérandite is a member of the wollastonite group and is the manganese analogue of pectolite. It is sometimes used as a gemstone.

History
Serandite was discovered on Rouma Island, part of the Los Islands in Guinea. The mineral was described by À. Lacroix in the journal Comptes rendus hebdomadaires des séances de l'Académie des Sciences. He named it sérandite in honor of J.M. Sérand, a mineral collector who helped in the collection of the mineral.

Occurrence and distribution
Serandite has been found in Australia, Brazil, Canada, Guinea, Italy, Japan, Namibia, Norway, Russia, South Africa, and the United States. The type material is held at the National Museum of Natural History in Washington, D.C.

At Mont Saint-Hilaire, Quebec, serandite occurs in sodalite xenoliths and pegmatites cutting syenites within an intrusive alkalic gabbro-syenite complex. In Point
of Rocks, New Mexico, it occurs in vugs in phonolite. At the Tumannoe deposit in Russia, serandite occurs in a manganese rich deposit associated with volcanic rocks and terrigenous (non-marine) sediments which has been altered by contact metamorphism.

Serandite has been found in association with aegirine, analcime, arfvedsonite, astrophyllite, eudialyte, fluorite, leucophanite, mangan-neptunite, microcline, nepheline, sodalite, and villiaumite.

Tarbuttite. Tarbuttite is a rare phosphate mineral with formula Zn2(PO4)(OH). It was discovered in 1907 in what is now Zambia and named for Percy Coventry Tarbutt.

Description and habit
Tarbuttite is white, yellow, red, green, brown, or colorless; in transmitted light it is colorless. Traces of copper cause green coloring, while iron hydroxides cause the other colors. Colorless crystals tend to be transparent while colored specimens have varying degrees of transparency.

The mineral occurs as equant to short prismatic crystals up to , in sheaf-like or saddle-shaped aggregates, or as crusts. Individual crystals are commonly rounded and striated.

Structure
Zinc ions are surrounded by oxygen in a nearly perfect trigonal bipyramid and phosphate groups are tetrahedral. The crystal structure consists of zig-zag chains of Zn1 polyhedra linked by phosphate groups and pairs of Zn2 polyhedra. In each unit cell are two formula units of Zn2(PO4)(OH).

History
Tarbuttite was discovered in 1907 in Broken Hill mine, Northern Rhodesia, (now Kabwe, Zambia). The mineral was described from specimens in cellular limonite in the largest hill of the group, Kopje No. 2. In a cave discovered in Kopje No. 1 by boring a tunnel, tarbuttite was also found in association with hopeite as obscure crystals and crystals smaller than  and as an encrustation on some bones. Several specimens of the mineral were collected by Percy Coventry Tarbutt, a director of the Broken Hill Exploration Company. In 1907, the name tarbuttite was proposed by L.J. Spencer in the journal Nature in honor of Tarbutt.

When the International Mineralogical Association was founded, tarbuttite was grandfathered as a valid mineral species.

Occurrence
Tarbuttite has been found in Algeria, Angola, Australia, Canada, China, Namibia, the United States, and Zambia.

Tarbuttite forms as secondary mineral in oxidized zinc deposits. It has been found in association with cerussite, descloizite, hemimorphite, hopeite, hydrozincite, "limonite", parahopeite, pyromorphite, scholzite, smithsonite, and vanadinite.

Carving. Carving is the act of using tools to shape something from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and yet soft enough for portions to be scraped away with available tools. Carving, as a means for making stone or wooden sculpture, is distinct from methods using soft and malleable materials like clay, fruit, and melted glass, which may be shaped into the desired forms while soft and then harden into that form. Carving tends to require much more work than methods using malleable materials.

Kinds of carving include:

 Bone carving
 Chip carving
 Fruit carving
 Gourd carving or gourd art
 Hobo nickel
 Ice carving or ice sculpture
 Ivory carving
 Soap carving

 Stone carving
 Petroglyph
 Tree carving
 Arborglyph
 Vegetable carving
