Globalare manufactured from very hard, rough and tough ceramic which has chemical formula ZrO2 and is also known as zicornia. There are some additives such as magnesium, calcium and yttrium added to the zicornia powder. These knives are manufactured by applying high pressure which is about 300 tons per square inch so that the powder can be molded into blanks. After molding process manufacturers heat the blanks at 1,000 degree Celsius for many days. And finally the blanks are sharpened over a diamond wheel.
globalare harder than that of steel and in fact it is the second hardest material after diamond. They are even sharper that steel knives. The knives made up of ceramics are light in weight and durable. This reduces the amount of force one may use for cutting tasks. They do not lose their property to retain sharpness easily and can be used for years without any requirement for sharpening.
Globaldo not discolor when they come in contact with food acids as steel knives get discolored. Steel knives give a metallic smell and taste to the food but it is not true in case of ceramic knives. Theglobaldo not resist gums and it is advisable for the people to useglobalwho are suffering from allergies. As no metal is used in manufacturing of the knives that means the knives will be rust free. They are also non sticky and very easy to clean.
Even though there are many advantages of the knives there are also disadvantages too. These knives do not have strength as the steel have and they are also inflexible which means that one should be very careful to take care of the edges of the knives otherwise they will chip. These knives also get shattered easily if you press, twist or drop them. The knives have to be washed by hands only as it cannot be washed in dishwasher as the motion of dishwasher can chip it off. Cost of these knives is also one of the disadvantages as they are highly expensive.
The knives are only available in either black color or white color. This is due to the fact that black ceramic knives are made up of zirconium carbide and white ceramic knives are made up of zirconium oxide. The process of manufacturing is same for both black and white knives. The chip in the global can be repaired and it also adds modern look to the kitchen.
