Tektites are a natural material and these from Thailand formed nearly 800,000 years ago in a massive asteroid impact event. They are found during road construction and in farmlands and today often in bomb craters in Southeast Asia.
These Thailand tektites came from the enormous Darryl Futrell Collection. The tektites were all acquired by Mr. Futrell in the 1960s -1970s. Splashform tektites come in all aerodynamic shapes which they receive as they fall back to Earth in a hot plastic state. They cool during their flight and hold their final shape.
