The above Kimberley Point has been made from an old piece of glass, the flat side of a Camp Coffee bottle. My aim was to retain the raised letters that spelled ‘chicory’ but it was not to be. If you look closely it is clear that there are bubbles in the glass and the section on the bottom left is the edge of one large bubble. These voids meant it was necessary to continually adjust in order to manage them, hence the small size.
This second point is made from a side section of an old glass beer bottle. This is similar to one seen in the Manchester Museum and the main issue here was managing the curve and the variable thickness of the glass. The proximal section on this piece was much thinner than the distal. I am happy with it as a point, but in order to get that feeling of sharp serration on the margins I need to get the initial invasive flakes deeper, to reduce the angles. So whilst the microwave turntable presented its own set of problems, the transition to using old glass has highlighted some interesting issues that need to be considered when attempting to make these points as aboriginals did: uneven glass thickness; managing a transverse curve on longitudinal section; and accommodating bubbles in the glass. All in all an interesting process.
