Re: Mortar not sticking
i used 10 sand, 6 fireclay and 2 PCL (portland cement and lime mix)
i put about and inch or beter of this mix around then entire oven as each chain was placed. i had a bucket of water with a sponge handy. after each ring i would gently sponge the inside to remove excess or to fill any voids. this alos kep tht efirebrick damp for the next ring. i woudl spread a bit of the fire caly for 1 brick, dip the brick in the bucket of water and put into place. it gives just enoug time to tap it into place but doesn't suck out the water immediately. with this mix i did the entire dome with the exception of the very top nearly form free.
hope that helps.
