[Stoves] GLASS for stoves .

Tue Dec 26 19:22:41 CST 2017

thank you Todd for your explanation. cooking in China is a long time task,
very long, if we say half of a day, it won't be too exaggerating.
Safety is so important in stove design. and kids like to play with mom
around stove. Chinese like stove to be heavy, immovable/stable, no gas
emission into house.and no surprising situation, safe all the time for all
kinds of fuel.
