Ground stone artefacts were mainly miniature mortars and pestles, limestone handstones, cut-marked slabs, small sandstone abraders, and pebbles with ochre residues.
Instead, sandstone abraders (not found in PPNB contexts), miniature tools, and worktables dominate, whilst statues and figurines also occur, all signalling a greater emphasis on bead-making and other crafts (Wright 1992).
The mechanism of the C&C tester is closely related to its name; however, the cutting portion of this test has been characterized as "impact" to differentiate this type of mechanism from the cutting action of the pico abrader

The three different laboratory abrasion tests are: Taber, Akron and DIN abraders.
The Taber abrader is a laboratory tester which uses a flat molded sheet as a test sample.
