France's New Living Rooftop Law
@Sir Cobalot France has become more than Palletable Cobbin-Friendly 👍👍 Living rooftops are not only welcome now, they are mandatory for large structures and encouraged for smaller structures that the new laws mandate. ✨Great opportunities exist abroad ✨ 🎉!Se bon!🎉 https://livingarchitecturemonitor.com/articles/france-new-law-supporting-green-roofs-sp22

Thanks for the elaboration @Michelle Caron !
2nd Workshop!
Hey Y’all, just wanted to let you know, that Aziel and I have decided to open up a second workshop to focus on the finish plaster of the cobin we build together. This will be from November 15-20th This should be enough time for the cob to dry so that we can then plaster it. If you want to join us for that as well, you are welcome, you would just need to pay for accommodation if any is still available. Just thought you should know first before we send it out. 🙂

Keep me thanks for the Kind consideration 🙏
Pallet, Cob school in Florida
Hey Y’all, just thought I’d share with you this little video of the pallet Cob classroom I worked on in Florida. You can see how we built it on a deck rather than on the ground in order to keep all the insects and wildlife around intact.

Doing an earthen plaster over a cob wall
I just thought I’d share this little video on how I am applying an earthen plaster on an existing Cob wall. When it dries, I’ll probably do a clay paint with 40 parts flour paste, 30 parts very fine sand and 30 parts clay with an oxide added to give the Plaster extra water protection. I’m doing this work now at the Cob Cottage company in Oregon . There will be many cobbortunities here if anybody wants to come help, although I don’t know if anybody in our group lives in Oregon. It’s an amazing place with a whole bunch of little Cob Huts built over the years during various workshops.

@Sir Cobalot Saying it rains alot in that part of Oregon is quite an understatement, so it is a true testament to your 'good boots, nice jacket and a great hat' mantra seeing how well(!) that is all doing.
Building a cob oven
I was working on building a Cob Oven today here in Oregon at the Cob Cottage Company and thought I would share with you the process. I mentioned the insulation…It’s also possible to make an insulation mixture with Clay and lots of straw packed tightly or lover rock mixed with Clay, or sawdust mixed with Clayif you don’t have access to perlite. I like using the pear light though because it forms together into a ball and stays pretty compact when putting it over the thermal mass layer. We will probably take out the sand mold tomorrow and get a few little fires going in the oven to dry it out before putting the insulation layer on. It’s very important to make a very dense cob mix of up to 80% Sand 20 % with not very much water so that it forms together into a ball and won’t slump when putting it on the oven this will also help to keep the oven from cracking. If your Oven does crack though, when you fire it up, don’t be too alarmed. it can easily be patched up.. It does help in the curing process to have the Oven dry slowly so small little curing fires are better than big raging fires for the curing process.

Excellent variation showing the sand-mold! It's always really great seeing the differentiating nuances with each of your builds @Sir Cobalot. By 'small fires', what flame height and diameter are you talking about, and for about how long (ball-parky-like). And, do you ever make your own firebricks?
