Rocketstove mass heater finishing

Hi!

We have built a rocket stove mass heater at our permaproject this fall and are now looking to make a nice finish on the cob structure, to make it more waterproof, less dusty and durable.
Does anyone have expierience or good iedas to make a finish layer with natural rescourses?

I heard about linseedoil for earthern floors but haven't seen it been used on heated surfaces.


Thanks in advance!

Hi Ben,

Do you have an idea on the mixture of terpentine and lineseedoil? Have you tried it yourself?

Thanks in advance!

I very much like this heater you have made.  I may have to borrow some ideas from you fren.  I hope you don't mind if I ask a few questions.
Does it run well?
Did you use a bell system for the bench, or is it pipe in cob?
