1, when choosing a casserole, look at the overall pottery of the casserole. Casseroles with good quality are generally very thin, mostly white in color, with good enamel quality, smooth appearance and good thermal conductivity.
2. When choosing a casserole, look at the overall structure of the casserole itself. A good quality casserole is very flat on a horizontal surface and will not tilt, and the whole pot body is very round and the inner wall feels smooth.
3. When choosing a casserole, you can listen to the sound of the casserole body and tap it gently with something. The sound is crisp and bright, and it is a casserole with good quality. If the sound made by knocking is dull, it is not recommended to buy it.
4. When choosing a casserole, you should choose it according to your actual use needs. For example, if you use it to stir-fry traditional Chinese medicine, you don't need to choose a casserole with better pottery, but a casserole with average price. If you stew, you should choose a casserole with better quality.
5. When choosing a casserole, look at the bottom of the casserole. When choosing a casserole, we all choose a casserole with a smaller bottom, because this casserole has better heat transfer performance and can shorten cooking time.
6. When choosing a casserole, you can also look at the overall thickness of the casserole. Different casseroles have different thicknesses. Generally speaking, it is recommended to choose a thin casserole for domestic sand, because the home is not as powerful as a restaurant.
In addition to the above, when choosing a casserole, you need to see if there are any traces of abrasive particles. The small sand grains raised on the casserole can be directly polished with a grinding wheel, leaving many pits after polishing. This casserole has a short service life.
