Lavoisier saw the expectant expression on the Regent's face and awkwardly coughed, saying, "Ahem, Your Highness, actually, our preparation technology is not yet capable of producing qualified railway pads, and the shock absorption effect of the wheels is quite limited.
"So the most valuable products at the moment are raincoats, rain boots, sealing rings, and buttons..."
The assistant beside him, oblivious to the mood, picked up a dark brown raincoat to show the Regent.
It's understandable why he felt proud. You see, this raincoat could sell for 9 francs!
Europe had long made raincoats from raw rubber, by applying a layer of raw rubber to the fabric, which was waterproof but became sticky in summer and hard as a board in winter, sticking to the skin.
Even at 8 sous apiece, no one wanted them.
But vulcanized raincoats completely solved these issues, making them comfortable and durable to wear, thus directly increasing the price by more than tenfold!
