At first, he didn't have these small wooden blocks and had to make them one by one, so the speed of making the pots was a little slow. Now, he had made a lot of these small wooden planks, all of which were made in the past few days. He only needed to shape them and measure the width of the pot. He estimated that he could make a set before dark.
These pots naturally didn't need a lot of wood. He would continue to set and assemble them tomorrow, and he estimated that he could make three sets by tomorrow.
If it wasn't enough, he would make more the following day.
Jiang Yue and Xue Yan helped to scrape the saltpeter off the big pot. When they were done, Xue Sifu chiseled the ice into pieces and poured it into the big pot in the courtyard to dry. Another big pot was filled up in a short time.
He was not in a hurry to use the pots, so he was not in a hurry to pour out the ice in the two small pots.
