This section covers critical inventions that revolutionized travel and industry. Key innovations include the creation of the compass using lodestone to aid sailors in navigation, and advancements in shipbuilding such as watertight compartments and caulking methods. The introduction of the paddlewheel boat allowed for efficient river travel, while the canal lock system enabled boats to navigate elevation changes. Additionally, the development of segmental arch bridges made construction more efficient. In early industry, the production of paper from mulberry bark, along with woodblock and movable type printing, drastically reduced the cost of printed materials. Finally, porcelain was created by combining clay, quartz, and feldspar, resulting in a durable and waterproof material.

Invention • Travel by Sea • Create compass—lodestone • Help sailors navigate and know which way they are going • Ships • Water tight • Invent caulk and compartments • Paddle Wheel boat to travel up river
Invention (con’t) • Canal Lock—raise and lower water and boats • Segmental Arch Bridge- allowed to be flatter and boarder than ones in Rome • Less material and stronger
Industry • Paper 1st to make • Used mulberry bark • Slowly traveled around the world • Printing • Woodblock Printing pg 198 • Movable type, separate blocks for each character • Place in flame • Lowers the price of printed goods • Used until recently
Porcelain • Combine clay, rock quartz, and feldspar • Baked hard and water proof
