Thank you @HandyDan. The 1500°F is the characteristic of Portland Cement I wanted to know. Certainly land management in planning for such an event is only right if building in a forested area. I know those with buildings in or near Yosemite and Glacier National Parks would appreciate knowing this information at this time.

A follow-up question would be then, is there a type of cement available which can withstand a higher temperature without getting real exorbitant in cost, but will still mix well using the Little Dragon?

When considering building in heavily forested areas the statement that aircrete is "fireproof" begs the question: Aircrete is fireproof to what temperatures?

Looking up temperatures at which forest fires burn ( http://wildfiretoday.com/2011/02/26/at-what-temperature-does-a-forest-fire-burn/ ): "Under extreme conditions a fire can give off 10,000 kilowatts or more per metre of fire front. This would mean flame heights of 50 metres or more and flame temperatures exceeding 1200°C (2,192°F)". Is aircrete able to withstand SUSTAINED temperatures of 1200°C (2,192°F)?

Therefore, will an aircrete dome remain fireproof to these temperatures?

@Doc Not necessarily answering myself, but I did want to say, THANK YOU, for starting some Tutorial posts. The Tutorial forum section is no longer empty! Yeah!

I see in the Product area of Domegaia that Workshops are available and the pricing. Also, questions have been asked about Workshops in the continental U.S., particularly the Southeast, Midwest, Upper Midwest, and in Maine. These are great and I look forward to learning more about these as they become available.

There is a Tutorials section of this forum area, but no entries. I was hoping to see some basic posts with Tutorials on various topics being available without posting the whole Workshop curriculum. I could not find a way to post an entry in the Tutorials section so I felt Workshops was the next best area to draw attention. I myself am interested in a Tutorial of some basic design considerations.

I have been sketching some ideas incorporating overlapping domes and also using a double envelope construction with an outer shell encompassing the inner shells. If that would be a topic to start getting entries in the Tutorial section that would be great.

Thank you in advance.
