My jug mould is finally finished. I certainly managed to drag that out. When I asked technician T to explain the outside fitting spare just once more with feeling, he asked incredulously "Are you still not getting this?" or "Is it still not clear?" or something similar. It doesn't help that the technicians come up with mysterious methods that aren't in any of my books. Above is an example - three wooden sides, a brick, a clay wall and clay flying buttresses. They make it up on the spot to confuse me.
