type of mass for top of stove????

I have a stove I built very similar to the Liberator Rocket Stove. I don't have room to put in a large mass bench like many off gridders are doing. I do have room on top of the stove. The question is what would be best to store the heat? I could use bricks or a metal bucket with sand. What would be the best thing I could use on top of the stove to continue to radiate heat Thank you

Build a smaller brick rectangle, next to your stove and plumb into it.
No, rule that says you have to make a bench.

Sand by it's very nature is insulative, not heat conductive or storing.  Best example, would be a beach exposed to a full day of summer sun, you can hardly walk on it (the surface)  but 1" below is perfect.  The same can be said about pebbles but to a lesser extent, and on up the ladder until you get to solid bricks, stone, and the like.
