No, but if its like the ones we had, its pretty easy. Tht is a tile was
laid over teh clill interior first, then provbaly weighted down, the
next day teh top layer could be moratterd on. In our case there was a
slid oag frame on tpp off or butted up to the top tile layer.

I see you're still writing in code :-)

What's a "slid oag frame"?

Solid oak, obviously :-)
