 Why is the clay cracked?

This is a question often asked by the pro, here, it is necessary to talk to you.

In fact, whether the pro bought porcelain clay or clay, clay or clay, ordinary clay or clay, snow clay or clay, clay end cracking or not, and the clay The relationship between itself is not much, more than 2% of the proportion, the remaining 98% is due to our artificial control.





Clay soft or hard

Our clay sent to the parents are moderate degree of hard and soft, because some parents want soft, some want hard, we do not have a way to meet the requirements of all at the same time, so the uniform do soft and hard mud. Some pro in the process of making pottery, because the mud is soft, so they do not add water from beginning to end, the result to the back of the pinch more and more dry, the work is not dry and began to crack; some pro in the process of making and fierce water, the result of the mud soft collapse, shaping can not be shaped up, some pro in order to do a good job quickly dry, put in the sun, or directly baked with fire, the result and cracked, and so on. The correct production method is very simple, as long as we do the process of pottery appropriate control of moisture, keep your hands wet, because in the process of pinching plastic, human hands are hot, is going to absorb the moisture in the mud, so we will feel more and more dry pinching, this time you have to get your hands wet to the mud appropriate to add a few drops of water, you can, do not need to add too much, the mud is too soft can not be shaped, in addition, the good Works, if directly exposed to the sun, the principle of thermal expansion and contraction, the blank is very easy to crack, so to be placed in a ventilated place to dry, dry to a certain extent, and then put outside in the sun is possible.



How to make clay will not crack

Summary.

1, the finished work is strictly forbidden to be exposed to the sun, to shade dry natural air dry, if necessary, the work covered with a wet cloth, in short, to slowly and slowly let it dry, the purpose is to crack, the operation to keep hands wet.

2, the work of some range of thickness is not uniform, will also be suitable for easy to crack, so try to uniform thickness.

3, Try to keep your hands wet and the table wet when making.

4, After the work is ready, you need to lay newspaper, wet cloth or put on the bottom of the original wooden board, can not let the work on too smooth non-absorbent table, this will affect the bottom of the evaporation of water, shrinkage is not synchronized to cause cracking.

5, the clay itself has been vacuum pumping, can not be too wet nor too dry, too wet is difficult to shape, too dry, easy to crack, so when dry, try to wipe your hands more, as long as the requirements to do even the general clay will not crack.

  

How to remedy after cracking

If the work is still cracked;

1,When the work is wet, we can dip our hands in some water and repeatedly apply foam to level it, add some wet clay and compact it with tools; increase the solidity of the cracked clay.

2, after drying if cracked, the remaining clay with water into thin some into mud, plus mud repeatedly coated, must be many times to fill the mud at once is not good, dry sanding flat can be.
1, our clay can be free of firing shape, but the strength is not high, is a natural mineral clay, is the need for professional kiln firing thousands of degrees high temperature to become porcelain, home microwave oven, oven, gas stove can not be fired into porcelain.

2, no firing clay composition is a polymer material belongs to the chemical clay, after making the work to be baked at low temperatures (about 150-180 ° C) to harden in order to preserve, after firing texture is a bit like the feeling of plastic, not fragile, the things made to do more decorative, such as it can not be used as a cup of water, but can be filled with water.

Their common feature is that they have good plasticity before firing, and can be made into various objects and things.
