evidence: 10 Remarkable Advanced Ancient Technologies Ahead Of Their Times [...] This amazing artifact clearly shows that our ancestors were far ahead of their time. In fact they were so advanced that they may even have been inventors of what we today call nanotechnology. This extraordinary cup is the only surviving complete example made from dichroic glass, which changes colour when held up to the light. When light is shone through the body of the cup it turns from opaque green to a glowing translucent red. The glass contains tiny amounts of colloidal gold and silver, which give it these unusual optical properties.

Highly advanced hardening techniques of the ancients as well as ancient castings of large pieces were widespread in antiquity. Our ancestors were in possession of an extremely sophisticated scientific knowledge of metalworking from an earlier civilization and evidence of this knowledge was found in different parts of the world. China with a long history in metallurgy, was the earliest civilization that manufactured cast iron and some of the ancient Chinese feats of casting iron are so impressive as to be almost unbelievable.
