This rock is generally of lower quality than flint and requires heating to ready it for pressure flaking.
Villa and her colleagues identified glossy areas on silcrete tools at Blombos that, they surmise, formed when the stones were preheated for pressure flaking. Other marks on the artifacts indicated that they had been attached to handles, probably as spearheads.
Baker Perkins flaking rolls are used by leading multinational and regional breakfast cereal makers worldwide, to convert cooked grains and extruded pellets into a wide range of corn, bran and multigrain flakes ready for toasting.
Flaking rolls are an essential module in the Baker Perkins Cereal Master TX and EX expandable lines.
Notes on the experimental manufacture of long blades and points by percussion flaking
. Occasional Papers in Anthropology.
* Northern Territory triangular points, which occur only in the precontact period on stone, are bifacial and invasively flaked using precise percussive flaking, with minimal pressure flaking to form straight (not serrated) margins, and are shaped into the form of an isosceles triangle.
* Kimberley points, which are invasively pressure flaked points manufactured on blanks formed by percussive flaking, in which each successive series of pressure flakes 'is taken along one margin and refines half of each face alternately' (1995: 92).
In developing the new Buhler flaking
line, care was taken to further improve sanitation.
Most notable of these is the alternate flaking
technique used to produce the bifacial cobble cores.
was done with an industrial ring flaker, immediately followed by drying in a commercial triple pass rotary dryer.
The objective of this work was to evaluate the performance of flakeboards manufactured from recycled CCA-treated lumber using two adhesives (LPF and MDI) and two common flaking
techniques (ring and disc).
