The construction of the glass kiln factory was something Russell had long wanted to do but never had the chance.
It should be noted that Russell's title as a grand scholar was achieved through the use of reading glasses. Now, reading glasses have become popular among the elderly nobility, but ordinary people, especially those who are serfs, still can't afford them.
Therefore, Russell was preparing to produce inexpensive glass and then make affordable reading glasses for sale.
Of course, this was just a side endeavour.
Once capable of producing glass himself, Russell could make other glass products, including telescopes and microscopes.
"Then I will have craftsmen build me an astronomical telescope. I want to take a good look and see which star system Dragon Sleep Continent belongs to!" Russell envisioned the future as he inspected the glass kiln factory.
