rmh burn tube try

hello
I just thought i would share a little trick I came up with i have been using dry wall mud to seal / lay the bricks, it works like fire clay but will break down after a day or two of playing with your designs. This is working really well for me to mock up the J tube and play with the fire. and it cleans off easy compared to mortar.

thank for the great form and the ideas that are on this sight
