I wonder if people could post information about the functional properties of materials used in rmh construction. For example: I'd love to know the heat-capturing capacity of various materials (sand, gravel, concrete, cob, water, oil) so I can strike a balance between weight and thermal mass in a second floor application.
Perhaps their are charts with this stuff?

Yes, at engineering toolbox!

Hi Satamax. I assume you mean the website engineeringtoolbox.com. Loads of stuff there, thanks. I was thinking more of simple charts and such though. I came across this site today www.greenspec.co.uk/thermal-mass.php which has some basic information without a lot to pore over. It looks like water is the best value in terms of high heat capacity with relatively low weight. How to integrate that into an rmh or even building mass?...Hmmmm. I understand that in Japan it's common to have bathtubs perpetually filled with hot water.

Well, Water, no thanks.
Yep, meant engineering toolbox.

An added bonus would be if you had information on tiles possibly used for lightweight mass storage.

Umm..
1) Water (as mass) looks good on paper. There are complications in using water that outweigh the benefits. Unless there is some specific issue that only water as mass can address, I'd not use it.
2) the terms "lightweight" and "mass" are kinda exclusive of each other.

2) the terms "lightweight" and "mass" are kinda exclusive of each other. Yeah, I know. I was only trying to come up with interior liner ideas for outdoor oven stoves. Something other than just plain old metal. Russian stoves got me on the track of using clay or stone tiles for a possible liner. I love cooking with mass so I always want to experiment with materials and designs. Learning as I go. I did check out the engineering toolbox.
