The Roman Glass That Changed China: Silk Road's Forgotten Cargo

Glass. Not silk, not spices — but Roman glass found its way deep into Han dynasty tombs, transforming Chinese art and technology. This episode follows a single shard of soda-lime glass excavated at Hepu, Guangxi, in the 1950s, and traces it back to the furnaces of Alexandria and the Levant. We explore how the Han emperors prized Roman glass above their own celadon, how the Parthians controlled the overland route, and how maritime monsoon traders from the Red Sea docked at Jiaozhi (modern Vietnam) to exchange Syrian glass for Chinese silk. Lucas and Luna unpack the chemistry of Roman natron glass versus Chinese lead-barium glass, the political chess game between the Han and the Parthians that rerouted trade, and the surprising discovery that Roman glassblowing may have influenced Chinese glassmaking centuries later. Specific figures include Pliny the Elder, who complained about the cost of Indian Ocean trade, and Gan Ying, the Han envoy who almost reached Rome but was turned back by Parthian merchants. This is a story of how a fragile, beautiful commodity — not jade, not gold — became the unexpected currency of connection between the world's two great empires. #RomanGlass #HanDynasty #SilkRoad #MaritimeTrade #Hepu #Alexandria #Parthians #Jiaozhi #PlinyTheElder #GanYing #Glassblowing #NatronGlass #LeadBariumGlass #IndoRomanTrade #Guangxi #FexingoHistory #TradeRoutes #AncientTechnology Keep every episode free: buymeacoffee.com/fexingo
