Glass Making Process

There are several steps to make glass. At the beginning, sand, soda, and limestone were put together and melted in a furnace with high temperature. Then, the melted material was separated to to forming process. First, the mixture was put in a reservoir that was connected with rollers. The mixture was flow to the rollers. As the temperature decrease, the mixture was flattened. The result the process was plate glass. Second process, the mixture was put in a removable mould. When it was cooled, it became bottle-shaped-glass.

The Story of Mumble Happy Feet

Hi.. my name is Mumble. But the other penguins in my neighbourhood usually call me with “Happy Feet”, Mumble Happy Feet. They call me like that because I can not sing like they do. Instead of singing, I usually “say” my feelings with moving my feet in a beat. It’s kind of “Tap Dance” that humans can do. I thought it was okay for the other penguins, I thought they can accept me the way I am. Whether I dance or sing. But I was wrong. The other penguins can not accept my dancing, they say bad things about me because I can not sing like them. That’s why, they call me Happy Feet.

Pressure Compensated Valve

As shown in the diagram, fluids enter the valve from the inlet and dividen into two flows. One fluid flow goes through the center hole of Opening B and get pass to fill the center tube of the Piston A. After the fluids flows into the tube, it will be pushed and pressurize out through the outlet that positioned right after the body of Piston A. These pressure are increased by the flow that also compacting the volume of the tube as an effect of the movement of Piston A when pressed by that flow that came from the inlet and pressurize the Piston A.
The other flow of the flow hits the wall of piston A surrounding the Opening B area, this pressure of mass flow fluid will push the Piston A to the direction of Spring C. When the piston finally reach the end of its lane and touched spring C, automatically the outlet valve that is located on the side of the tube will be closed. When this outlet is closed, the fluid that enters Piston A through Opening B will be trapped and holded inside the main tube of Piston A. These processes are united in one whole cycle that would repeat itself one after another as long as the fluid flows and will stop when the fluid stops.

The Key of Making Excellent Espresso

To make an excellent espresso, one has to pay attention to the key factor, which is, the pressure. To get the pressure right, a cup of water might be needed to make two solid ounces of espresso. First, pack the coffee tightly and add some water. Make sure the water is enough. Then turn the stove on. Watch closely as the espresso-in-process brews. As soon as the first ounce come out of the brewer, pull it off the stove. Then, the second ounce of espresso will come out shortly after. As the instruction before, one cup of water is enough to make only two best-in-taste ounces of espresso, so do not ever overbrew it. Just keep in mind that quality is more important tha quantity.

Steps in Making Glass

Men, generally, take these steps to make glass. The first thing to be done is get the glass basic materials (consist of sand, soda, and limestone) mixed in a furnace. Then, the product gets separated into halves and both were put on different places. First half of the mixture has to be flattened using rollers. The flat half of mixture is then cooled to make it solid. The result of this first half of mixture is called a plate glass. The other half of the mixture is poured into a type of removable mould and then get blown with air so that it will take shape of a bottle. After this bottle shaped mixture is cooled and freed from mould, a bottle glass can be taken out as the product.

The glass making process

Glass is made throughout several steps. First, set up ingredients and instrument required to make glass. The main ingredients consist of soda (Na₂CO₃), sand (SiO₂), and limestone (CaO). Then, mix up all of ingredients in the furnace. After that, burn the ingredients at certain temperature. Leave the mixture in the furnace, so that all compounds have melted. The next step, the molten is divided into two processes. First process, the mixture is passed through a roller. Hence, we get a flat glass. Second process, the molten poured into removable mould and blown by air. We get then bottle glass from this process.

holiday

I really like holiday. It is a chance for me to refresh and relax my self because I don’t have to study a lot. On holiday, I can wake anytime, take some exercises, do some homework, review some lessons, go to some interesting places, hang out with my friends, and even sleep all day long. Besides offering pleasant day, I can also plan what I’m going to do tomorrow.

Glass Making

If we want to make glass, whether it is a plate glass or bottle glass, there are few steps that we should do. First we mix sand, soda, and limestone in a furnace. Next the mixture are being flown into two different shapping container, a bottle shaped removable mould to make bottle glass and a container with rolls after it. To make a bottle glass we pour the mixture to the removable mould. Then we blow air into the mould so that the bottle would have space inside. To make a plate glass, we pour the mixture to another container and flown the mixture through rollers. To make the mixture flat.

Making Glasses

There are some steps to make glass. The first step is gathering the main ingredients such as silica (SiO2) which we can get in the form of sand, then soda (Na2CO3) and limestone (CaO). Second step is mixing the ingredients in a furnace. The third step is heating the furnace until the furnace reaches a temperature of approximately 1,500°C. After being molten, the molten glass can be formed into two form.
The first form is plate glass. The molten glass is poured into a melting pot, then the molten glass will flow through some rollers, so we can get the thickness we want.
The second form is bottle glass. The molten glass is poured into a removable mould. Then air is blown from a blowpipe into the mould. The molten glass will follows the shape of the removable mould and forms the bottle glass shape.
Then the plate glass or the bottle glass is cooled down until it gets it's solid form.

HOW TO MAKE GLASS

Glass is made by several steps. Firstly, the compositions (sand, soda, and limestone) are mixed and melted at high temperature (about 3600 F) in the furnace. After amount of time, the mixed compositions will become liquid and it will be separated to become different kind of glass. The first one will become plate glass as it brought to the rollers. Another one will be brought into removable mould which is filled with air inside it so it will be bottle glass.

Glass Making Process

There are a few steps to make a glass. Fist, we put sand, soda, and limestone into the furnace and mix it well. In the furnace, the mixture are being processed to become liquid, and that would be the main item to make 2 kinds of glasses. Bottle glass and plate glass. To make the bottle glass, the mixture that is in the furnace are being flown to the removeable mould that shaped like a bottle. In the removeable mould, after we pour the mixture, we blow air to it so it shaped like a bottle with a room in the middle of it. To make the plate glass, the sand soda and limestone mixture are being flown to a different place, this time to a container that was connected to a rollers. After that, the rollers will flattened the mixture and make it a plate glass.

Water Pump

Almost every house has water pump. The water pump pumps water from ground to water tank, which is usually located at high place.
Then the water is distributed to water pipes.
By storing water at water tank, the system has some advantage.
First, the water always stand by and ready to use even if water from the ground is dry.
Second, the pressure of the water is higher than directly from water pump. Some water usage such as shower need this kind of high pressure.

Glass processing

Glasses are made by simple procedure. The materials and the compositions could be different depending the purpose.
First, the materials, such as sand, soda, and limestone, are put in furnace to their melting point until they become liquid.
Then, the liquid is distributed to mould to be formed as bottle, plate, and many else..
After the liquid hardened and take the shape of it's mould, then the mould is removed and the glass is ready to use.

TRAVELING

I like traveling so much. I always enjoy traveling whether it is a long or short vacation. Everytime I travel, I always find something new and it’s just so interesting to know new things. I find new cultures or habits that are very different from my own and there are always fun things to discover from other cultures. When travel, I meet so many people, which each person comes from a different background and ethnicity. By then, I can make more friends and connections. Never say no to traveling, because there will be new experiences, new friends, new knowledge, and entertainment in a travel .

Why Choosing ITB as a Place to Study?

There are several reasons why I choose ITB as a place to study. First, lecturers in ITB are number one in their occupation. They are graduated from magister and doctoral program in accredited university around the world. Second, ITB is always in big five universities in Indonesia. Even, in the latest SPMB, score of ITB’s new student is in the first rank. Third, ITB is located in Bandung. I choose ITB, because it is near by Jakarta, where is my family live.

glass, how it comes

There are several common steps in making glass. First of all, prepare the basic materials. They are soda, sand, and limestone (a type of white rock, containing calcium. Second, melt them down in a furnace (an enclosed space or room for heating e.g. metal or glass to a very high temperature, OXFORD Advanced Learner’s Dictionary). This process takes time for six hours. After all the materials are melted down, this dough can be separated into two purposes, for making plate glass and bottle glass. Plate glass is made by using roller that flattens the dough. In other hand, bottle glass is made by using mould that forms the dough into bottle. Blowing air on the top of mould makes the dough formed faster. After all, the mould can be released. Those are the common steps of making glass.

How to make a glass

Several steps are required in the production of a glass. First, the materials which include sand, soda and limestone are reduced to powder. After the coarse parts are sifted, they are heated within a furnace of high temperature for five or six days. The result of the heating process, which appear in liquid form, will be sent to two places. The first place liquid will be shaped by rollers and later be cooled to form a flat shape. This process will produce the a plate glass. The second place liquid is put in a mould and be blown by air. The liquid is then cooled and removed from the mould when it is cool enough. This process is meant to create a bottle glass. These are the basic steps for producing the two type of glasses.

Glass Making Process

There are three steps in the glass making process. First, we have to collect some materials such as sand, limestone, and soda. Then, put the materials in the furnace which have thousands celsius degree temperatures. In the furnace, those materials will be melted and mixed. After that, to make a plate glass, pour the mixture into roller pins, let the roller pins pressed it, cool it down, and get the thin flat glass. To make a bottle glass, pour the mixture into a removable mould, blow by air, cool it down, remove the mould, and get the bottle shaped glass.

How to Make a Glass

           There are some steps in making glass. The first step is mixing the basic materials (that is sand, soda, and limestone) in a furnace. Next step is melting the materials in a certain temperature in the furnace. The mixture from the melting process then divided based on the product that wanted to be created. To make a plate glass, the mixture is flattened using a roller. To make a bottle glass, the mixture is placed in a removable mould and then blown by air to make a bottle shape. The last step is cooling the mixture so it last appearance is a glass.

Process of Making Glass...

Making glass has several steps, which can’t be rearranged. First, we have to prepare the materials used to make glass, such as sand, soda, and limestone, and the tools like furnace, roller, and removable mould. Then, the materials are mixed (by reducing them into powder). After that, they’re heated in the furnace, preferable in the constant temperature for about 5 to 6 hours. The result of this heating is divided into two places according the shape desired. In the first place, the melted mixture is flattened by rollers and cooled into a solid plate glass. In the second one, the melted mixture is distributed into the mould, given air pressure, and then cooled. After the solid bottle glass obtained, the mould can be removed. Finally, the glass products are ready to sell or use.
