Lithic technology are skills and techniques used to produce tools from various types of stone.
Ideal stone characteristics include: non-crystalline or glassy, which allows for the right cryptocrystalline structure and conchoidal fracturing.
Being conchoidal, and cryptocrystalline, is a characteristic sometimes easier to picture in your mind. Think, flint, chert , or jadeite used in projectile points and scrapers. It is the way materials fracture when they do not follow natural planes of separation. Cryptocrystalline is minute rock texture, that its crystalline, and revealed microscopically.
Strong lithic technologies have smooth, curved surfaces, slightly concave, with concentric undulations. Similarly to lines on a shell (like on a high end spear head or scraper).
Given the correct features, a hard surface like granite; hammer stones, bones and sticks, the mason, (or flintknapper), is able to control his ‘lithic technology’ skills and ability.
Types of Lithic Stone included:
▪ Silcrete, and
North, South America, and European ‘lithic technologies’ have been dated to around 10-15000 years.
Online sources claim 2-3 million year old tools could have been found around Ethiopia.
