Looking at building a budget oven and need help

[norcalmx]

Now im curious, almost looking do to a temp but maybe end up keeping it full time. I was thinking of using a plastic pond or bucket "to ice down a keg" as a mold. Set that mold on top of fire bricks and boom. The more I read the more I find people use soooooo many diff materials. Im not going crazy I just wanted basic and use once in a while. Im curious what material to use for the mold. I have the bucket cut out with a exhaust stack,,,,,,why don't people use cement with chicken wire under? Can I do cement with some powder fire clay? Just fire clay? Really was thinking the wire would hold it together well. However im very very amateur at this obviously. Basically it works in my mind but prob reality it wont. Has anyone made one of these things with products from the local home depot or lowes hardware? All the info would be great. Thanks guys sorry I just see so many options I wanted to narrow down what im actually trying to do.
