Photograph Tobacco plants, Tobacco fully grown prior to start picking, Circa mid to late 1900's
This promotional photograph by the Tobacco Growers Association was in response to a 1935 meeting of tobacco growers from Victoria, South Australia and Queensland which produced four major resolutions for the industry covering the remainder of the 1900s. These four resolutions were: (1) Adequate tariff protection (2) Control of pests and diseases (3) Orderly marketing (4) The formation of an advisory council of growers. History has produced the following results. (1) adequate tariff protection was never achieved,(2) control of disease through benzol vapour (CSIRO) breakthrough, was later identified as carcinogenic, (3) orderly marketing was achieved through (4) the establishment of the Tobacco Growers Association(1984). In October 2006, by way of Government buy back of tobacco leases from growers, resulted in the end of Tobacco farming in Australia (after 136 years of planting the first crop). It was also significant that the major tobacco companies such as Philip Morris and The British American Tobacco Australasia advised the industry that it would source its tobacco requirements overseas by 2009.The remnants of the Tobacco Industry can still be viewed throughout the Kiewa Valley and adjacent regions on the former tobacco farms which still have the tobacco drying sheds and now converted into hay sheds. The problems from the large quantities of carcinogenic infused soil of farmlands in the region, still remains a problem now and for future generations. This particular photograph shows the lack of understanding by farmers, at that time, and is demonstrated by the lack of protection of hands and no masks over their noses, when handling plants. Hand, nose and foot protection was rarely used, even when later warnings were issued of the carcinogenic toxicity of the soil. The majority of farm owners, up until Health authorities stepped in the latter stages of 1900s, were skeptical of city scientists' "carcinogenic" health warnings and it was only after the younger generation of farmers, who had graduated from Agricultural colleges, encompassed the scientific approach to farm management. The "she'll be right mate" attitude of the farming/rural community has since the 1970s been slowly dissipating. Stricter controls of herbicides and pesticides used in agriculture are now in force. The death of the tobacco industry(2006) resulted in the expansion of the dairy , sheep, beef cattle, venison and lama wool producers in the Kiewa Valley and surrounding regions.Coloured photograph pasted onto a thick wood chip backing.

Leisure object - WOODEN MODEL CYANIDE PLANT
Wooden model of a cyanide plant. A cyanide plant was used for dissolving gold from finely divided ores by means of dilute solutions of sodium or potassium cyanides. The model has five metal bins, there is some rust on the bins and scorch mark on the wooden base.mining, equipment, cyanide plant, gold cyanidation (also known as the cyanide process or the macarthur-forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. it is the most commonly used leaching process for gold extraction. the ore is comminuted using grinding machinery. depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity) concentration. water is added to produce a slurry or pulp. the basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide, however many operations utilize calcium cyanide, which is more cost effective. to prevent the creation of toxic hydrogen cyanide during processing, slaked lime (calcium hydroxide) or soda (sodium hydroxide) is added to the extracting solution to ensure that the acidity during cyanidation is maintained over ph 10.5 - strongly basic. lead nitrate can improve gold leaching speed and quantity recovered, particularly in processing partially oxidized ores. -

Artwork, other - Public Artwork, Home by Chris Mether, 2014
Home is a collection of birdhouses on floating islands using the iconic form of the human house - a pitched roof, square walls, windows and doors. This minimal form is often drawn by children; a dolls house, a cubby house, a letter-box or a chook house. Home creates a safe refuge for birds with the plants acting as a water filtration system. The exposed roots draw out pollutants, such as nitrogen, phosphorous and toxic metals, which have entered the waterway through urban run-off. The result is a beautiful sculptural experience and a healthier water system for all to enjoy. The artwork was funded by The City of Ballarat and The Victorian State Government.The work is of aesthetic significance to the people of BallaratHome is a collection of birdhouses on floating islands home, chris mether, studio mether, public art, ballarat, delecombe, wetlands -
