| You Are Looking To Buy: 290 Gram Rough Natural Rock Specimen Dark FLINT FIRE ROCK Knapping Striker Stone - Ohio, USA!
Features: Flint is a hard, tough chemical or biochemical sedimentary rock that breaks with a conchoidal fracture. It is a form of microcrystaline quartz that is typically called "chert" by geologists. It often forms as nodules in sedimentary
rocks such as chalk and marine limestones.
The nodules can be dispersed randomly throughout the rock unit but
are often concentrated in distinct layers. Some rock units form through
the accumulation of siliceous skeletal material. These can
recrystallize to form a layer of bedded flint. Flint is highly resistant
to weathering and is often found as pebbles or cobbles along streams
and beaches. Heart.
Flint has been used by humans to make stone tools for at least two million years. The conchoidal fracture of
flint causes it to break into sharp-edged pieces. Early people recognized this property of flint and learned how to
fashion it into knife blades, spear points, arrowheads, scrapers, axes, drills, and other sharp tools using a method
known as flintknapping. If these tools were broken or damaged in use, they were often reshaped into smaller tools
of similar function.
The value of flint for making sharp tools was discovered and utilized by Stone Age people in almost every early
culture located where flint could easily be found. Their survival depended upon having a
durable material that could be used to produce sharp tools. One of the most important localities for flint in eastern North America is Flint Ridge in eastern Ohio. Native
Americans discovered this deposit and produced flint from hundreds of small quarries along the ridge. This
“Ohio flint” occurred in distinctive colors and was treasured by Native Americans. They traveled hundreds of
miles to collect it and spread the distinctive material in trade across eastern North America. It has been found
as artifacts as far south as the Gulf of Mexico and as far west as the Rocky Mountains. Total Weight Is 209.6 grams (10.2oz). Measures ~3-1/2" Long x 2" Wide x 1-1/2" Thick!
