Liszt honestly did not know much about lime and cement. He only knew that both were produced by calcination and were very common.
But as for the exact connection between them, or what they were composed of, he was not too clear on that.
"However, if I remember correctly, I once watched a documentary about China building the Mombasa–Nairobi Railway in Africa. It mentioned the problem of cement production—because of a shortage of raw materials, the Chinese experts ultimately chose local volcanic ash as one of the raw materials for cement?"
When he had watched that documentary, Liszt had felt immensely proud. It had been a tremendous achievement of his homeland. What had left the deepest impression on him was that cement could actually be made with volcanic ash.
So.
Thinking of this, he immediately went to inspect the Fire Dragon Brickworks and offered the craftsmen responsible for developing cement a new line of thought—mix lime with volcanic ash and see whether they could develop cement.
As for volcanic ash, Dodo Island had plenty of it, but the eight-hundred-kilometer voyage was a little too far.
Coral Island also had an eroded extinct volcano. Liszt had once gone there to search for signs of magma, and volcanic ash could be excavated from there.
Liszt did not need to concern himself with such mundane affairs. He merely needed to provide a general direction.
