... evaporation techniques... food preservation evaporation techniques farming painted pale ...Meat safes were used to keep meat and vegetables cooler before the availability of ice and then kerosene or electric refrigerators. The safe would be placed on a bench in a cool place. Water would be placed in a small container on each leg to stop ants getting into the safe there would be another water container at the top also to stop the ants. Pieces of damp hessian would then be hung over each side. As the wind hits the hessian it causes the water to evaporate and the items inside the safe to stay cooler. This meant that the items inside the safe would last a day or two longer. Meat safes were being used throughout the time period showcased by the displays at Churchill Island and this expands understanding of how refrigeration worked prior to electricity.painted pale yellow metal meat safe with square grid hold pattern for air flow.

Tools, Blow-torch brass, 20thC
A blowtorch is a fuel-burning tool used for applying flame and heat to various applications, usually metalworking. Early blowlamps used liquid fuel, carried in a refillable reservoir attached to the lamp. Modern blowtorches are mostly gas-fuelled. Their fuel reservoir is disposable or refillable by exchange. The term "blowlamp" usually refers to liquid-fuelled torches still used in the UK. Liquid-fuelled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation. In 1882, a new vaporizing technique was developed by C. R. Nyberg in Sweden, and the year after, the production of the Nyberg blow lamp started. It was quickly copied or licensed by many other manufacturers. The US blowlamp was independently developed with a distinctive flared base and was fuelled by gasoline, whereas the European versions used kerosene for safety and low cost.The family of Mr Howcroft were early settlers in Moorabbin ShireA brass blow-torch B.A. HJOP Co.
