Why was the production of porcelain such a closely guarded secret?

The production of porcelain was a closely guarded secret primarily due to its high value and the significant technological advancements it represented. Originating in China, the unique combination of kaolin clay and specific firing techniques created a strong, translucent material that was in great demand globally. Keeping the methods secret allowed China to maintain a monopoly on porcelain production for centuries, ensuring economic prosperity and cultural prestige. The loss of this secret would have jeopardized China's lucrative trade and influence in the world.
