Bowl coating

This is an experiment wherein two pieces of briar were cut from the same block and exposed to an open flame. One was coated with a mixture of sodium silicate, pumice, and activated charcoal. The other was left as "raw briar."

This brief experiment tests the claim that, because Sodium Silicate is classified as "anhydrous" on Material Safety Data Sheets, that a mixture of sodium silicate, activated charcoal, and pumice will form a hard "glass like" layer preventing moisture from passing through the coating and, therefore, creating a "wet" smoke.

I got It! Thanks! But I don't think if I use the raw briar(Non-Charcoal) might burn like that, usually I smoke peace and not so fast wouldn't cause that burn

实验证明烟斗保护层确有阻燃作用，谢谢jt师兄！
不过，这个是最严酷的实验，抽烟斗应该极少人可能达到这个程度，即使有，也是短暂的时间会“过热”，否则，口腔、舌头会受不了
以我自己的经验，无预制炭层的裸壁烟斗，抽过20斗以后的炭层就很完美了，抽过50斗以后，即使用砂纸打磨平整斗壁也看不见烧伤
但是，建议新手还是使用有炭层的烟斗

All kinds of the dry woods are easily burned. In the ancient China and western countries , people mainly use woods for cooking and keeping warm in winter.

Therefore, what the briar of pipes with some chemical liquid made should be necessary in production process.
