In addition to the 3 small LDG tools, published as an MPOD Classic for 26 November 2021 , here are 3 bigger neolithic tools:

77 grams / 84 x 42 x 23 mm

88 grams / 101 x 58 x 23 mm

123grams / 118 x 75 x 18 mm

In contrast to the Noerdlinger Ries impact, which produced the beautiful Moldavites, the asteroid which most probably exploded in the atmosphere above todays Great Sandsea region about 30 million years ago obviously did not form a crater. But it left behind a richness of types, differing in size, form, color, transparency and sometimes inclusions, of the likewise beautiful Lybian Desert Glass. It is especially fascinating to see how human interest in this extraordinary matter continues through time. The LDG was formed into tools (blades, scrapers, arrowheads, spearheads etc.) in the neolithc period c. 6-10,000 years ago, and it adorns as a centerpiece, formed as a scarab, King Tut anch Amun's (14th century b.c.) legendary necklace.

Usually it's not difficult to recognize a piece of LDG as a tool: one can find artificially generated and often conchiform shaped immersions, single or in series, creating extremely sharp edges.
