Working on the new fire proof chimney

I liked my red brick design a lot, but fire bricks may be a better
idea for a long term. Here is a new design I am testing with oven. I
think it is not open enough. I may need add extra holes.

My oven stamps

Now I stamp my gift pizzas : ones I wrap for guests in aluminium foil
and paper;-) such pizzas are still OK to eat next day or can be
frozen. It is nothing like fresh hot pie, but a nice kind of bread
anyway. Thank to my dear wife I have a personal cool stamps and red
ink pad;-) Cool!
