Establishing a glass plant from scratch was a task that requires a lot of precious time that Linus do not have. While he had its construction in his plans, Linus didn't count on it to produce the piece of equipment that he needed. After all, he needed only a few of them for military use, which he believed Raymond can produce for him. The only trouble that he had was to acquire the raw materials for it.
While it was easy to acquire lead as it was the byproduct of gold and silver extraction by his dedicated chemists, he didn't have immediate access to silica sand, also known as fine white sand. As he already thought about this problem before he acquired the skill of glass making, he penned Samir to acquire a bulk of it in the white sand beach of Whitesand Town. For the moment, Linus could only wait for the shipment of sand coming his way.
