TROMAX BRAND / PURPLE CRYSTALS ...Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO4. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. c1859 London chemist Henry Bollmann Condy had an interest in disinfectants; he found that fusing pyrolusite with sodium hydroxide (NaOH) and dissolving it in water produced a solution with disinfectant properties. He patented this solution, and marketed it as 'Condy's Fluid'. Although effective, the solution was not very stable. This was overcome by using potassium hydroxide (KOH) rather than NaOH. This was more stable, and had the advantage of easy conversion to the equally effective potassium permanganate crystals. This crystalline material was known as 'Condy's crystals' or 'Condy's powder'. Potassium permanganate was comparatively easy to manufacture.A brown glass bottle with a red plastic topped cork stopper for 'Tromax' , 'Purple Crystals' ie Permanganate of Potash , that was used as an antiseptic and disimfectant.TROMAX BRAND / PURPLE CRYSTALS/ or Permanganate of Potash / (Poisonous )/ For Household and Medicinal Uses / 2oz. / TROMAX / A PRODUCT OF/ SIGMA Co.Ltd. / MANF.

Decorative object - Silver toned Faux Crystal Necklace from the Sarah Coventry Jewellery Range c. 1970s - 1980s
... Faux purple crystal pendant set in a claw clasp... Range c. 1970s - 1980s Decorative object Faux purple crystal ...Sarah Coventry Pty. Ltd. was a North American jewellery company that was established in 1949 by the Stuart family as part of Emmons Jewelry, Inc. It began operations in England and Australia in 1968, and in Australia it moved from Carlton in Melbourne to Wodonga in 1969. The premises were originally on High St. in Wodonga, but a new warehouse was built in Melbourne Rd. later in 1969. It was a direct selling jewellery business using a party-plan model similar to Tupperware and Avon. The sales reps or 'Hostesses' were provided with jewellery samples in demonstration kits, which they displayed at jewellery parties in their homes. The designs for jewellery such as brooches, necklaces, earrings, chokers and bracelets were purchased from freelance designers and jewellery manufacturers rather than in-house designers. In 1979 Sarah Coventry Pty. Ltd. in Wodonga was bought by three Australian businessmen, including Wodonga local Jim Sawyer, and continued to sell jewellery under the name "Sargem Pty. Ltd”, for several more years in the 1980s. As part of the Sarah Coventry collection, the necklace has local significance with the decentralised commercial development of regional centres such as Wodonga in NE Victoria, as well as national and international significance from the perspective of social and economic developments for women after World War II. The direct selling party-plan business model Sarah Coventry was based on is also considered the first of its kind for jewellery.Faux purple crystal pendant set in a claw clasp ,with silver tone chain."(c)SARAH" on back of pendant sarah coventry, jewellery, wodonga, costume jewellery, vintage fashion jewellery, necklace, necklaces -

DENTAL SURGEON WARRNAMBOOL .2 POISONOUS NOT TO BE TAKEN PURPLE ...These two bottles have been used in the business of Melsom Hemmons a dentist who operated from the chemist shop of R.F. Kennedy & Co. in Timor Street, Warrnambool. Hemmons was a close friend of Richard Kennedy who established a large wholesale, retail and manufacturing chemist business in Warrnambool in the 1880s. This business was regarded as the largest and best appointed pharmacy in Victoria for many years. The business continued until the 1920s trading as R..F. Kennedy & Co. These two bottles are of considerable interest as mementoes of two prominent Warrnambool identities of the past- Melsom Hemmons and Richard Kennedy..1 A brown glass bottle with a metal top and a white label with faded red writing pasted on.

Geological specimen - Fluorite (purple)
Fluorite comes in a variety of natural colours and crystal formations and glows under ultraviolet light (the word 'fluorescence' comes from the same etymological source). In its pure form, calcium fluoride, it is a colourless combination of the elements calcium and fluorine, but gains its colour from trace elements that infiltrate or replace calcium within its crystal structure during its formation. Although fluorite crystals polish well and can achieve a high level of lustre, the mineral is very soft (4 on MOHS hardness scale) so it is unsuitable for use in rings and must be handled and stored carefully if used in other forms of jewellery. Most crystals of the mineral are too coarse for decorative purposes but have been mined under the name fluorspar for a variety of commercial and industrial purposes. These include the production of hydrofluoric acid, smelting metal alloys, producing glazes and ceramic finishes and use in medical and dental products. An existing label for this specimen indicates that its origin or collection-point was 'probably USA.' Fluorspar, the form of fluorite used commercially and industrially, was mined in significant quantities in the counties of Hardin and Pope in South-Eastern Illinois throughout the Nineteenth and Twentieth Centuries. Fluorite was made Illinois' state mineral in recognition of its contribution to the state's identity and economy. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.The specimen is a piece of purple shaded fluorite (also known as fluorspar), the mineral form of calcium fluoride. The unpolished specimen presents a dark purple interior with a substantial dark grey crust representing the matrix from which the specimen was obtained.

Geological specimen - Chalcopyrite, Unknown
This specimen was recovered from Mica Schist, Canada. Chalcopyrite is a copper iron sulfide mineral with a chemical composition of CuFeS2. Its name derives from the Greek words for copper (chalco-) and brass (pyrite). It can be found in shades of yellow, green and grey, and, when exposed to acid, it can change to purple, blue, violet and yellow tones. Weathering can cause loss of its metallic luster and its brass-yellow colour. Chalcopyrite forms under various conditions, with the most significant deposits being hydrothermal in their origin. It is known globally as the most important ore of copper for thousands of years, and is thus considered a very important mineral formation. Given its golden appearance, it is often confused for the mineral gold, earning it the popular reputation as 'fool's gold' or 'yellow copper'. However, it can be straightforwardly distinguished from gold; the latter is soft, with higher specific gravity and a yellow streak, whereas chalcopyrite is brittle, easily scratched by a nail, and has a greenish grey streak. Copper was the first metal that was used by people. It was discovered by the Neolithic man about 9,000 years ago and it gradually replaced stone as it was easier to be shaped. In Australia, search for copper began after the European settlement, leading to the discovery of substantial deposits, like the one at the Olympic Dam in South Australia, which is regarded as one of the largest copper deposits in the world. Chalcopyrite has been used for copper since smelting processes began approximately five thousand years ago. Although by no means rare, this the specimen of this mineral can be used to reflect a wider history of industrial uses of copper for a significant portion of human history. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A solid hand-sized copper iron sulfide mineral of brass yellow, often with an iridescent tarnish, with greenish-black streak and submetallic luster. Chalcopyrite can be formed in several ways, including crystalizing from accessory minerals in igneous rocks, or from magma or within volcano sulfide deposits. Most commonly, chalcopyrite are found in hydrothermal conditions, where it forms in hydrothermal veins. As a member of the tetragonal crystal system, it often takes the shape of tetra-headed crystals, often with striations along the sides of the crystals. #18 Copper pyrites/(chalcopyrite) in/Laurentian Slate/(page 315 of inventory)/page missing from/descriptive catalogue/ Other label: 81 /fool's gold, chalcopyrite, mineral, rock, geology, geological, hydrothermal, neolithic, european settlement, olympic dam, south australia, stone, deposits, specific gravity, greenish grey streak, brittle, mineral gold, metallic luster, cufes2, greek words -

Paint set, Artist's paints, Late 19th century
These items are a collection of paints etc for those artists wanting to produce lustroleum and crystoleum works of art in the late 19th century and early 20th century. These works of art using lustroleum and crystoleum which were mainly metallic paints, were produced on a variety of surfaces, including glass, wood, tapestry, china and ivory. These items have no known provenance but it is known that lustroleum and crystoleum painting were popular pastimes with women in Warrnambool in the late 19th century. There are several records of women advertising classes in lustroleum and crystoleum painting in the 1880s and 90s in Warrnambool. One was these was Annie Newcombe, an art teacher who offered classes at her studio in Timor Street in 1884.This is a metal tin with a metal catch and a hinged lid. The tin contains 10 items - four glass bottles of Lustroleum, one glass bottle of gold paint, one glass bottle of purple metallic paint, one tube of green paint, one china bowl with a lip for pouring, one dish to hold paint with a broken base and one small dish for holding paint.

"Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO4. It is a salt consisting of K+ and MnO−4 ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. (Which is what in contained in the bottle.) As an oxidant, potassium permanganate can act as an antiseptic. For example, dilute solutions are used to treat canker sores (ulcers), disinfectant for the hands and treatment for mild pompholyx, dermatitis, and fungal infections of the hands or feet. Potassium permanganate is used extensively in the water treatment industry. Historically it was used to disinfect drinking water.
