Bunjil Park Aboriginal Education & Cultural Centregrinding stone, Double sided grinding stone with multiple hollows
... Double sided grinding stone with multiple hollows...The very hard and dense nature of the rock means materials would not be contaminated during the grinding process....The base rock is in the shape of a flattened and slightly elongated sphere, it appears to have been water worn. Double sided grinding stone with multiple hollows grinding stone ...Grindstones like this were not carried but hidden in special places with subtle indicators known only to the same tribe or nation. The small and deep nature of the pits suggests this rock may have been used for ochre with the smaller pits being used for water or fat to mix with the pigments. The very hard and dense nature of the rock means materials would not be contaminated during the grinding process.This rock is likely to be very old and is potentially significant from ceremonial perspective. Stones like this have been known to be passed on through multiple generations and been in use for hundreds and possibly thousands of years.This grindstone has hollows on both sides. One large hollow on one side measures approximately 7 cm across and 2 cm deep. The opposite side is distinguished by 3 pits, one large (5 cm wide by 3 cm deep) and two small indentations 2cm by 1cm. The hollows have been chipped and smoothed. The base rock is in the shape of a flattened and slightly elongated sphere, it appears to have been water worn.The side with three pits also bears recent scratches believed to be cut by a disk plough. It also appears to have a capital "W" inscribed in the largest pit.jaara, hidden, grindstone, ochre, quartzite, multiple hollows, pits, aboriginal food and art -

Grinding stones are slabs of stone that Aboriginal people used to grind and crush different materials. Bulbs, berries, seeds, insects and many other things were ground between a large lower stone and a smaller upper stone. This is the lower stone.Large grinding stones such as this one were designed to be left at a camp site for use the next time the group moved there. Smaller grinding stones were carried between sites. Grinding stones were not abandoned when they became worn and smooth through use. The stone would simply be roughened again so it was once again suitable for its function. This is an example of a food preparation utensil used by the Early Indigenous people of Eastern Australia.A large flat rock with grind hole in top.

In conjunction with its grinding stone was used not only to grind seeds and but also to dig up eatable roots and leaves and served with the regions Bogong moth. This method of food preparation has survived in its basic form for centuries and is still used by master chiefs in modern eateries. This item has been registered with Aboriginal Affairs in Wangaratta, Victoria. Dhudhuroa elder Alan Murray has examined this tool, in Feb 2015, and said it was also used for sharpening axe heads as well as pounding food items. This item has a very significant historical and social aspect to it. Firstly it demonstrates the division of labour within a indigenous tribe. It was an era when the female had a definitive role within the family and the broader social indigenous tribal group of, gathering and preparing non animal(hunted) food. Hunted food was the domain of the initiated males of the tribe.Secondly it demonstrates the ability to fashion implements from raw materials(rock) into effective tools for the purpose of preparing a meal for human consumption. This was in an era where inter family and intra family participation in an indigenous tribal social protective environment was at a very high level. The Kiewa Valley/Mount Bogong region was an area where annual "get together" indigenous tribes for feasting, bartering and settling of disputes highlighting the importance of a regional gathering. Grooved stone, carved to a cylindrical shape with a relative pointed end tip one side (grinding or pounding end) and a rough other end (holding end} Made from Rhyolite stoneThere is a worn grove in the top side due to this tool being used for axe sharpening. indigenous, aboriginal, stone grinding, meal preparation, natural environment, pounding stone -
