Tim Bassett is on a distinguished road
My stadelman has a layer or two of hot face fibre close to the crucible and then a few layers of standard fibre to back it up. I would not suggest using bricks in case you do need to do a big cleanout. The worst case scenario is that the fibre can never be actually "glued" on place by the glass, you can always shred it and pull it out. I would hate to have to shred a brick that has been glued in place. Hopefully you will have to use the cleanout port very infrequently. I opened my cleanout port after charging at least weekly for 18 months and was surprised that there seemed to be so much glass on the floor...maybe 1/2 an inch. I spent quite a while gathering it all off the floor and it added up to be about three kilos. Best of luck with your build
