Archaeologists have found a variety of items used in glassmaking, including this ceramic container(photo), at an ancient Egyptian glass factory. Glass was colored and heated in this vessel, which is about 7 inches across. The inset shows glass ingots from a Bronze Age shipwreck near Turkey that fit Egyptian molds.
Indeed, just like being the first black mayor or the first black astronaut, some Whites and Non-Whites around the world today cannot accept nor believe, or have difficulties to admit(like Kris) that Black skinned ppl were the first to be civilized enough to drink from a glass.
Thanks for sharing this point about Kemet, bro.
