I am in the process of building my own pizza oven as well, actually just finished the slab for it and ready to start the dome. one thing that i have read MULTIPLE times is to actually use perlite NOT vermiculite. One perlite is made from lava ( much better for heat ) second the ratios I have come across are 2:1 as 5:1 sounds like it wouild be way too crumbly
