Image 2: Deep holes resulting from cracked tiles – the enamel factory claims proudly that it never cuts corners. Image 3: Products made with a spirit of craftsmanship. Feel free to discuss; I will continue to provide further explanations
I don’t get it – there’s no inevitable connection between the thickness of the enamel and cutting corners in production, right? High-quality products don’t necessarily have to be very thick either. :(
Could you explain it in more detail? So that we laypeople can also learn about it
These are enamel products manufactured using two different processes; the first two images show the process used in most parts of China, while the latter one represents the process that has been introduced from abroad. The quality can be determined just by looking at the appearance: 1) The first two images show a rough surface, with internal cracks that are visible under light; there is also color variation, along with many impurities. In the areas where the glaze has cracked, the thickness of the glaze is significantly excessive. The treatment at the R corners is inadequate; it lacks the luster that enamel should have. 2) On the last image, I’ve included a flange with a large opening to demonstrate the quality of this company: (1) The enamel has a high degree of luster; (2) The roundness and flatness of the large flange are quite good (enamel needs to be baked in an oven at nearly 1000°C for 6 times), and such large flanges tend to deform easily; (3) Look at the R corners. These are all surface-level issues – it’s the details that determine success or failure, and enamel is indeed a product where attention to detail is crucial
Regardless of the manufacturer, enamel is a product that places great emphasis on details. It’s impossible to do a good job with enamel by relying on deception and superficial efforts. When working with enamel, it is essential to pay attention to every detail; one mistake can lead to failure overall, which is a very apt description for working with enamel
Some domestic brands of enamel products are also quite mature in their production; we purchase a large quantity of them every year. They are among the well-known brands, and we’ve never had any problems with them
There has indeed been improvement in the past 5 years, but there is still a big gap between some smaller enamel factories; larger enamel factories are able to recruit talent and develop their technologies more rapidly
