Chapter 12 Firing

Roland stood by the kiln in the backyard, waiting for the first batch of cement to be released

The brick house that he had designed for the ce and four meters wide The front and back each had a door, the front door was as spacious as possible, it was so that people could easily transport materials into the house Instead the back door was only one person wide, the only use was to let Anna secretly into the firing room

Therefore, he also built a hich was halfway around the house, the ihts — they were Carter’s men, their loyalty was beyond doubt

The cement production process was very sirinded into powder, afterwards it was mixed with clay, iron powder, and then it would be calcined with either a dry or wet ether with the plaster The raw materials were very common, only the iron could be difficult to obtain and hold in a large nu the right calcine temperature

Roland did not remember the specific temperature needed to produce cement, even if he did re and controlling the temperature – whether it ith an infrared therun both tools were unavailable, this made the production of the cement countless times more complex He only knew that the te point of iron, and that the calcination process was also a difficulty in the production of cement

In the era of less advanced s the temperature of the furnace has been a problem for all people The heat loss of an ordinary open furnace was too great; it was difficult to rees But then he would also require a high teure out how toblast furnace would be heated up to the point of , the temperature may be up to the standard, but the narrow chamber was too small for cement calcination to take place, Roland was afraid that the tih for him to prepare all of this

Therefore, Roland’s design for the kiln did not have any heating measures, he relied purely on Anna’s capabilities

The broken-down particles of liether ater into a slurry, this was then evenly spread within the kiln The knights then locked the door and walked away Afterwards Anna would enter from the back door, use her fire to bake the earthen slurry until it melted into the iron powder

Roland was so Border Town If he couldn’t produce ce a wall in three months would be just empty talk Without the wall, there would be no people ould be willing to stay in this place Whether it was in real life or within fictional literature, if you wanted to progress, a stable base was always essential

“Your Highness, can this kind of product really hold the stones together?” Carter, standing at the side of the fourth prince asked Although the prince had told him that this was the latest results from the research of the alchemists of Graycastle, he was still skeptical After all, those people really haven’t made any useful products so far

“Who knows? Anyway, that’s what they said it would,” Roland spread out his hands in resignation

The world of alchee arts In the eneral, the royal faers,fate For ordinary people, these studies were too classy In light of this, Roland would naturally make the source of cement formulas out to be froht believed him or not, it didn’t matter

Through thethey could see the fla, it seemed that the calcination was complete

When Roland stood up and went to take a look, Carter had been driven away fro alone by the front of the backdoor for the brick

The gates creaked open and Anna walked out The First thing Roland did was to drape a robe over her body, then brought a cup of water for her, “How are you?”

The face of the witch was full of dust, due the wet processing system and the amount of dust was also low, but the hot air needed for the calcination still produced quite so inside for more than 10 hed and nodded, “The slurry has already changed into powder”

Roland waited until the teh he needed to wrap a wet towel around his head, he still grabbed the shovel and stepped into the back door
