I’m Still Too Weak For The Starter SSS Talent

Later, it was discovered that quartz sand can be refined to produce glass with higher purity and more transparent material, which gradually replaced sand in the production of glass.

But it is a pity that Tang Zheng has no quartz sand on hand now.

If you want to make glass, you still have to rely on the gravel all over the floor.

The sand and mud in the wetland environment are fused together.

It is also very simple to purify.

Get a wooden bucket and fill up some water by the lake, grab a handful of dirt and throw it in.

It didn't take long for the mud to dissolve in the water, and the gravel settled to the bottom.

Use linen cloth to spread the big rocks at the door of the house, pour out the water in the bucket, and all that remains on the cloth is gravel.

Making glass is not troublesome.

Of course, it’s just not troublesome for Tang Zheng who owns the furnace.

Others want to make glass, and it is more difficult than firing earthenware.

At least one crypt that can be heated to over 1500 degrees is needed.

First find a stone with enough weight and throw it into the synthesis platform to make a rolling pin-shaped stone roller.

Pave the refined gravel on a flat stone surface.

Use the stone roller to roll back and forth to further refine the grit.

The purpose is to dry the water in the gravel to keep the raw materials dry.

The next step is to throw it into the furnace for calcination.

When the temperature of the gravel rises to a certain point, it will change from a solid state to a semi-liquid state.

Tang Zheng took a closer look at the inside of the furnace and found that the burning glass was sticky, like a large piece of clear nose.

After high-fire baking, a completely cooled glass precursor is obtained.

Pour a basin of water for quenching and shaping.

It only took less than half a day to extract, process, and produce raw materials.

A simple piece of glass is finished, and under the noon sunlight, it emits colorful rays of light.

It's just that the sharpness is not high, like a long-wearing colored lens, a piece of fog.

【Ding! You have successfully made'glass'. Since you are the first player in the world to make glass, you have received a random first prize-a bag of acorns 1! Bronze civilization progress (5/8)]

[Alternative Acorn (Excellent Grade)]

Seedling period: 10 days

Growth period: 15 days

Description: Don’t look at it small, when it grows up, you won’t be able to stand it......

......

What kind of words are this tiger and wolf? describe.

Those high-ranking people usually delve into human culture and customs?

Tang Zheng in the heart murmured secretly.

But this reward is what Tang Zheng wants.

High-quality oak, the wood material must be very good, and it is very mellow when used for wine.

Apart from this, used to make furniture and floors, can also be waterproof and moisture-proof, and reduce the humidity in the house.

This is necessary for Tang Zheng who lives in a wetland environment!

The most important thing is!

The oil produced by acorns can be refined and used as edible oil.

After the acorn itself is ground, it can also be ground into acorn noodles and become one of the staple foods.

There are too many benefits.

Tang Zheng immediately dug ten pits in the soil next to his house, separated by a few meters.

Plant all a bag of acorns.

When I entered the Half-Iron Age, these trees grew up and they were just for my own use!

Chapter 49 The Painted Glass Window Who is playing a period of wandering, sadness [second more]

Sunset Western Mountain.

The day of survival Twelfth gradually came to an end, and ten full jars of mixed fruit stuffed were covered with a lid and sealed with water.

Tang Zheng used the method of burning to put a little bit of dregs left over from the fruit wine made yesterday on the bonfire together with a clay pot.

The fire is burning! Evaporate the wine!

In this process, some useless impurities will be removed.

Pour another pot on top of the clay pot.

After the bottom of the wine dregs burned almost, the inner wall of the inverted empty earthenware pot was already covered with moist alcohol beads.

Next, just place the clay pot normally and wait for the alcohol attached to the inner wall to flow down along the gravity.

This is the most primordial alcohol distillation purification method.

The purity of the purified alcohol is obviously not as high as medical alcohol.

But for disinfection, in the current stage of civilization, it is already a good choice.

But up to this step, the branch line of'medicine' cannot be completed yet.

A certain effect must be exerted on the wound to meet the conditions.

But he was healthy the past few days, and he didn't even have a bump.

The first thing to protect in the wild is your body. A small wound is very likely to be infected with unknown germs in the wild. Tang Zheng has been handling this very well.
