Machine - Scouring Bowl, J Dyson & Sons Pty Ltd, c.1890
... Souring Bowl... from c.1890-1970. Souring Bowl J Dyson & Sons Geelong Wool ...Scouring is the process that removes wool wax and other unwanted products from wool. Wool is washed in a hot detergent solution. It moves through a series of scouring bowls and is then rinsed and dried. Careful handling and washing preserves the strength and softness of wool. If the wool contains lots of seeds and other vegetable matter, it must be cabonized. This means it is treated with a solution of sulpheric acid and then baked at high temperature to remove impurities. The disused scouring water left-over from this process was often let drain into rivers and watercourses causing pollution. Many of Geelong's wool scours along the Barwon River were closed due to environmental damage. The race system on this bowl is not the original it has been modified with a variation of the harrow system. Used at E.P. Robinson South Geelong from c.1890-1970.Scouring bowl.J.

Functional object - Milk/Cream Separator
This device would separate the cream from milk using a hand operated lever. When turned, the lever would activate a disc which would spin the separator bowl at a great speed. Through this use of centrifugal force, the cream would gather in the middle while the milk would be pulled towards the outside walls of the bowl. Once the rotation ceased, the milk and cream would flow out of two separate spouts. Prior to the invention of the separator, gravity was used to naturally separate the cream from the milk. The cream rose to the top and was then skimmed by hand. This process was lengthy and often resulted in sour milk, so the invention of the mechanical separator was popular in the dairy industry as there was less waste and encouraged greater production levels. Alfa Laval is a Swedish company founded in 1883. Beginning with domestic farm machinery and dairy products, they expanded to heavy industry and are still successful today.
