Whether the overall color of rattan furniture is consistent, whether the bonded parts are stable and whether the appearance is correct are the main factors to test its quality.

2. The difference between Japanese cast iron teapots with and without coating.
Compared with uncoated iron pan, coated iron pan can increase the water temperature and have stronger heat storage capacity.
The coated iron pot can soften the water quality, release ferrous ions and form a mountain spring effect. Introduction: 1. Cast iron teapots originated in ancient China and then spread to Japan. In recent years, with the upsurge of tea ceremony and the improvement of living standards, the series of cast iron teapots refined by combining traditional production technology and modern technology are also popular in China.

The burner is called "the heart of the cooker". As the core component of the cooker, the cost of burner accounts for 1/3 of the total cost.
However, the different air intake modes of the cooker are related to the safety, power and energy saving performance of the cooker. The air intake mode of embedded gas stove burner can be divided into "upward air intake" and incomplete upward air intake.
One of the best air intake methods is "headwind". At present, Italy Sabaf, which is mainly used in China, is a professional manufacturer of "headwind" burners.
Experts commented: "The burner in this way has reliable safety-the glass panel will not explode due to tempering, which is clean and conducive to maintaining a healthy atmospheric environment. However, the air intake is a little small, and the heat load of the furnace head is difficult to meet the high standard requirements.
Experts also said that most of the so-called "up-suction" cookers in China are not really fully enclosed "up-suction". Incomplete upper air intake includes "side air intake", "backward air intake", "downward air intake" and "three-dimensional air intake". It is characterized by large firepower and adjustable firepower, which can meet the needs of Chinese people. Disadvantages are poor cleaning, especially potential safety hazards. Tempering may lead to bursting of tempered glass panels.
