Information About Glass, Porcelain and Ceramic
What is glass and how to produce it?
Sand the main ingredient of the glass. Sand is one of the most frequently found materials in nature. The material made of pure silica, obtained only by sand melting, is very fragile. In order to increase both the resistance and to reduce the melting temperature, soda is added. limestone to remove the instability of the against water and chemicals, dolomite and feldspar minerals such as eklenir.har bearing called secondary raw materials in the form of glass fracture, the mixture is added, and is ready for being dissolved in the oven.
When melted in a glass oven at 1500 ° C, the desired color is transformed into soda-lime glass which is a fluid liquid with honey content. Molten glass is cut into drops and automatically pressed and blown on machines or by blowing twice, bottles, jars, glasses and so on. Shaped. The obtained glass products are then cooled in a programmed manner, passed through delicate quality sensors on the line, the faulty ones are separated. This completes the production process.
Glass is hard and stagnant when touched by hand. Due to its fragility, it is crushed when hit hard. Along with this, the chemists say, "The cabinet in which we drink water through is a liquid in itself."
All of these are the main features of cold, stagnant glass. However, when the high temperature is removed, these properties of the glass change completely. They start to soften first. Then it gets fluent. Even if enough heat is provided, it "flows like water".
Glass is defined as a mine. But there is a very important change compared to other mines. It is not "melting point" but "softening point". Because of this important feature, if the temperature of the environment in the glass is increased, it becomes more and more liquid and fluent. This allows the glass to be shaped and blown in many different ways.
Why should we opt for glassware?
- Glass taste of foods, provides long-term storage unchanged smell and flavor.
What is Porcelain?
Porcelain; only produced from natural source raw materials, not the whiteness of the dye used, the area of the material used, about 1400 ° C firing reinforced by having light transmittance is described as a healthy product.
Porcelain; Is a member of a large ceramic group, made entirely of clayey clay, or of products made from raw materials that contain clay, to put it more explicitly.
We can refer to the definition of two types of porcelain produced as home and hotel groups. Home porcelain is the porcelain that passes the light when it is held to daylight. The hotel group is produced thicker, according to World standards. When they are held in a lamp, they can be seen to have a light. Nowadays, restaurants take the service by preheating the plate to keep the temperature of the food put into it. If the plate is thick, it will keep the temperature longer and add flavor to your taste.
Porcelain is divided into hard and soft porcelain according to its raw materials, proportions and temperature grades. The most important feature of hard porcelain is the feldspar glaze which is formed at its high kaolin ratio and at a high temperature of 1400 ° C. This, in turn, creates surface hardness and durability. Soft porcelain is low in kaolin ratio and glaze temperature is lower. For this reason, it has less mechanical stiffness and impact resistance than hard porcelain.
Why should we prefer Porcelain Products?
- means health and cleanliness.
What are the key points to consider when using Porcelain Products?
- There is no problem in heating the porcelains in the heating sections of the ovens and in the microwave ovens. However, direct contact with bare fire creates a shock effect on the porcelain and causes it to break. For this reason, the porcelains must never be put on bare fire.
- Porcelains can be used with the same confidence in deep freezers. However, if the porcelain emerging from the freezer is immediately introduced into the furnace, the porcelain is broken due to the sudden temperature change. For this reason, the porcelain should come into contact with the heat after reaching the room temperature.
- If you use your porcelains in a region with lime water, white stains may form over time in the porcelain. However, such stains can be destroyed with vinegar.
- Metal cutlery can leave traces on porcelain surfaces. These marks are normal and do not cause any damage. Porcelain glazes become harder than materials such as metal stainless forks and knives because of their hardness at high temperatures. This causes metal wear and black marks. To remove these unwanted traces, a special formula, soft, non-abrasive cleaner can be used.
If you are washing your porcelains by hand
- Your washing cabinet should not be copper or aluminum.
- There should be no porcelain items besides your porcelain, such as pans, pots, cutlery, knives.
- Use hard cleaning materials or cleaning with wire, liquid and cream cleansing materials should be rinsed and dried with plenty of water.
- The plates and cups must be placed on top of each other and inside when the porcelain is raised. When the plates are laid on top of each other, it is useful to put a thin paper between them. Otherwise, unglazed dough at the bottom of the plate may damage the glaze and gold décor due to its hardness.
If you are washing your porcelains in a dishwasher;
- If you have gold in the decor of your porcelain, it is recommended to hand wash. As it is known, it is a gold asset and by its structure it is also exquisite. For this reason it should be used very carefully. - If your porcelains are decorated with glaze or under glaze, the decoration will not be erased in the case of washing with machine.
- Porcelains should be washed in a warm wash program that does not exceed 60 ° C. - The detergent used must be tested for glass and glaze decorations. Besides, the amount of alkalinity it contains should not be high.
- An absolutely anti-scale detergent should be used. Otherwise, a whitish lime layer forms on the porcelains. This is especially true for areas with high water content of lime. - Detergents and other rinse ingredients should be used at recommended ratios.
- The machine water should not be so high as to move the press, porcelain and glassware.
- Porcelains should be placed with care, sticking to the layout of the machine.
- It is useful to wash before the food remains. Because dried food leftovers can be heard for a longer, more elaborate cleaning, which can cause decorations to be damaged.
