Bubbles may form when the clay is ready and should be removed to avoid cracks in the jars you make.The process of removing bubbles from clay can be done manually, called Clay wedges.Clay manufacturers use a special machine called pug mill to extract bubbles from clay.Bubbles in clay are dangerous because they cause an explosion in the kiln.Bubbles expand due to heating, forcing the clay to break or explode and breaking the ceramic sheet.As the temperature inside the kiln increases, the risk of explosion increases.Explosions usually pose a risk only to items with bubbles, and other items fired under the same load are usually safe.However, the debris generated by the explosion may fall on the element of the kiln (the coil inside the kiln), which in rare cases may lead to a short circuit.Wedging is the process of kneading the clay to make it more uniform and is also used to remove bubbles from the clay.This process is more commonly used in the family-Because commercial Clay has been made into a uniform paste and compressed, it does not contain bubbles.The wedge is made on a flat surface, such as on a table or board with your hand.Cut the amount of controlled clay down and press the heel of the hand over the clay.Clay is treated using circular motion.This process is similar to kneading noodles.Cut the clay in half with a clay cutting line and check for bubbles.Repeat the wedge if you see the bubbles captured.A large number of clay manufacturers use pug mill to remove bubbles from clay.Clay is extracted from the soil and mixed with water.Remove impurities and rock particles and then dry the clay to the desired consistency.The clay is inserted into the pug mill, mixed and rolled out from the machine, resulting in airbubble-free clay.This process is similar to an artificial wedge, but a large amount of clay can be compressed at a time.The most common bubble in the handPottery, but may occur in throwing or slidingThere are also casting ceramics.In order to minimize the occurrence of bubbles, it is important to properly wedge clay before using clay.After building a jar, always check if there is any empty space in the building, such as the binding position of a clay coil or slate, and apply some sliding or liquid clay to cover the space.Do not add clay plates or a small amount of hard clay to cover the empty space as you may catch the air in the jar.
