Given there were no refrigeration techniques in Victorian or early Edwardian times then common foodstuffs had to be made as pickled, preserved or contained in airtight cans and bottles. There were numerous sauces, chutneys and pickles made and sold to assist in making often tainted meats taste palatable, or as a primary food item.
According to antiquebottles.co.za website, there are a large number of different household bottles of these types to be collected, and this website has information and photos of common bottles of this type.
Western Australia had a few prominent manufacturers such as H. Rayner and Co, and Sovereign Products, but in general we imported a lot of these type of preserved food stuffs from interstate and overseas manufacturers. Many of the goldfields era foodstuffs were imported into this state.
