A Powerful Scraper Duo from Eemster
This matching pair of scrapers—a classic side scraper and a specialized notched scraper—was discovered at the exact same location and shares an identical raw material signature.
Material Properties and Chert Patination
While discussions regarding regional assemblages often look for a mirror-like wind-lacquer typical of glassy flint, these tools consist of a high-quality local chert. Chert features a matte, fine-grained, limestone-rich structure that responds differently to environmental exposure over millennia.
Instead of a glossy polish, this specific material naturally develops a silky, milky surface glaze known as soil sheen. The absence of a high-gloss wind-lacquer is a direct result of the material properties of the chert itself, rather than a lack of age. This material identity is confirmed by immediate visual comparisons with other documented chert samples from the identical Eemster context, which exhibit the same matte textures, color ranges, and unique chemical weathering patterns.
The Shared Chert Signature of Eemster
Regarding the raw material, the specific mineral properties and weathering patterns of these scrapers align perfectly with the known chert varieties and similar known pieces from the same geological source. The toolmaker targeted the chalky white-grey outer crust to expose the sharp, caramel-brown interior, intentionally driving off flakes to create a distinct, hollowed working edge along the profile of the notched scraper for specialized scraping purposes.
The heavy, matte patina flows uniformly across both the remaining natural rind and the worked facets. This continuous chemical weathering provides concrete physical evidence that the tool edges were knapped in antiquity, linking the specific patination of this chert duo directly to the wider prehistoric record of the Eemster assemblage.
