where to get a stone that holds heat?

I think it is, I think you have to put it in the oven for a time.

There are some microwaveable rocks too. I think they are granite.

Try a glass chopping board or two. Or, if you really want to be cheap, a 1 litre carton of whatever heated to near boiling.

You should be able to get a stone offcut from a monumental mason, free. Any old stone should work.

I just ordered a marble slab. We'll see how I get on with that.

OK but its limestone so don't use direct flame.

I am told soapstone is the stuff to use, apparently cooking pots can be made from it. Some cultures cook on "injera" which are directly flame heated ceramic hobs.

In the Pacific they use heated stones to line a pit in the earth for feasts. IIRC basalt is much used, possibly by necessity on volcanic islands. Of course you get the advantage of insulation from the earth there too.

According to Google injera is a kind of bread.

Old night storage heaters. Free to collect quite often (except for chiropractor's fee) and contain many super-dense blocks.
