The seams go up on the pipes. Be sure to bed the pipe well in cob and surround it completely with cob.
I would guess adding calcium chloride might be ok... maybe. That's what they use as a dust control on gravel roads. It is a moisture attractant though, not sure if that's such a good idea.
A better way would be to have a stove burning. Either build your core and plumb the exhaust thru the mass area. Then cob as you burn OR...
Have a small box stove in your yurt that will keep your cob warm enough to build with. Its going to be rough but you can do it. As soon as possible start burning your rmh core and piping , cob and rock lasagna your mass, heating every day.
By the way ... Got DRY wood yet ? You will need it.
Looking forward to photos

Thanks for the instant reply - very helpful. I built a rudimentary rumford into the wall which works great for heating me - so hopefully that will help. I built a mass quickly and in a bit of a panic - and think I got the mix too wet - so I am deconstructing. I was curing the mass with my old rocky estufa - piped into the mass - I think that combo will work - good thought on the salt attracting moisture - I think I will give it a miss. Thanks for the seams up info. I will send pictures and the story once I can say "I did it" rather than "I'm gonna do it"!
Thanks again, much appreciated.

New topic - Is pine a legitimate primary fuel source - seems hardwood is preferred.
A friend of mine is having two large pines cut down - and I am looking at them thinking - hmmm - that could be ten years of fuel for free rather than paying for disposal. Big logs which I was thinking I could stack outside as a wind break and then use as needed. (of course won't be dry yet - so maybe next years fuel - though pine seems different (less water - more sap).
Tried searching the forum but have not found a definitive answer.
on a side note - I cut my had pretty badly - spent a night in the hospital (note to self - do NOT put your finger in your mouth!) so all my clay froze - but it has given me time to revisit the videos - and my book arrived the day after so I read the whole book in the hospital (both doctors were interested in the project) - so the delay is going to end up being a good thing - though frustrating....
Also trying to type without a left index finger is challenging so sorry if I have a weird stilted style - ha ha
