官网上的解释是让油进入孔后改善烹调效果 。我的理解是黑搪瓷只是外表面有孔，但和铁的接触面是无孔的，所以

Staub能标榜锅不会生锈。
搪瓷材料实质上是玻璃，因为玻璃并没有不沾效果，所以Staub做出多孔表面，留住油慢慢形成类似裸铁锅season的效果。但这种搪瓷表面的season是不牢固的，所以每次烹调需要较多的油来维持。

What are the benefits of black matte enamel over a shiny enamel?

Our black matte enamel is virtually indestructible and delivers excellent cooking results. Your Staub Cocotte will gradually burn in as the fats used in the cooking process penetrate into the pores of the black matte enamel. The black matte enamel will gradually go brownish ensuring better cooking results each time you use it!
