Gan Tian was a little shy from her straightforward praise, but then she thought about it and said worriedly, "But this is not cheap! So much saltpeter is needed to make such a small basin of ice."
Moreover, she overheard outside that ten catties of saltpeter cost half an ounce of silver. Spread out on this small basin of ice, and considering the cost, it's hardly cheap; in fact, many people probably still can't afford it.
Ganli replied, "If we have to buy saltpeter every time we make ice, it's indeed not cheap. But what if the saltpeter could be reused?"
Can it be reused? In other words, for the price of saltpeter once, you can make ice cubes indefinitely?
If that's the case, then this is truly a highly profitable business!
However, Gan Tian still had some doubts: "That's certainly good, but it takes ten catties of saltpeter to make this little bit of ice. If we want to make a large quantity, we'll need to prepare a lot more saltpeter and wooden basins. And transporting the ice will be a headache if we want to sell it..."

However, she had considered the issues that Gan Tian mentioned, so she never intended to sell ice cubes from the beginning.
She decided to start small, beginning with selling popsicles.
