The copper ingots were smelted yesterday, and they were long strips, like firewood, and were not regular and flat, and they were piled up in a small pile in a mess in the straw shed.

Next to it is a rugged square cauldron, with large and small bubbles on the outside, and a few are missing, like a ball of black hard rag after heavy use.

Fang Chang calculated the amount of fuel left in the charcoal pond and slowly planned it in his mind. He planned to put it aside first about the idea and plan to cast the cauldron first.

As the saying goes:

If you want to do a good job, you must first sharpen your tools.

As the saying goes:

Sharpening a knife will not delay chopping wood.

Fang Chang prepared to make some tools first, and then use these tools to improve the quality of labor to ensure the production of this cooking utensil.

He began to list in his mind what work he needed to do next and what tools he needed in these work.

First of all, it is the stone axe used to pick up the tree, so it is best to replace it.

The metal axe will be much more efficient, and the axe will be thick and solid in shape, simple in shape, and suitable for casting. As long as it is solid enough, it will not be easy to make failed products that are prone to collapse.

Plates have always been a shortcoming in Fang Chang's work. If you don't want to use an axe to slowly chop and cut a tree, and only one wooden board can be produced, a bronze saw will definitely be a necessity.

Since the saw tooths need to be staggered left and right to avoid clip sawing, this work is not simple and has some technical content.

In addition, a shovel is also excellent.

I always use stone slabs to dig soil, but the efficiency is not good. Although Fang Chang is very suspicious, if I don’t use tools, I just use my ten fingers to dig soil, the speed will be faster than that of an excavator, but the posture will be too indecent.

Think about it, I bent on the ground like a cat and a rabbit, digging with my hands, digging up the thrown soil flow like a fountain, pouring into the air behind, gradually piled up the soil...

That's so scary.

If you have enough time and energy, you can also try the planer and ore draft. The former can be used to plan and polish the wooden board, and the latter can eliminate the need to use an axe to knock it when mining.

Walking into the straw shed, picking up the failed square cauldron yesterday, and hitting the square long right palm.

Bang—!Bang—!

The copper-tin ratio in this bronze is well matched. It took a little effort to smash the copper cauldron and turn it into a small pile of bronze blocks and put them together with the copper ingots. They will all be the raw materials used for casting tools.

This time, Fang Chang learned his lessons and first considered creating an axe.

He was not familiar with this, and he could not prepare molded sand. Fangchang finally chose a rather ancient method:

Use loess as the model.

Find the materials and take them in the back basket. Slice the bamboo into thin bamboo strips, cross them into dense grids, and then wrap them on top to make a round sieve.

The pile of loess was dug, and then used this sieve to filter out the gravel, wooden sticks and other debris. The remaining one was fine loess as fine as sand.

In this era, this is likely to be a common practice.

Find a piece of wood to chop into an axe style, leave the axe handle to perforate, place it in the loess to beat it, and make the loess solid. The next step is simpler. Give this piece of soil dry over fire, remove the moisture in it to prevent the bubble holes, burn the wood mold in it, and then blow off the ashes.

Start the furnace and burn the fire.

Several pieces of bronze were put into the jar and calcined together in the furnace. Since the bronze melting point was low, a jar of copper juice could be obtained soon.

Fang Chang reached into the stove and picked up the jar.
