What should I line the bottom of my forge with?

[Colton C]

I welded togther a small steel box with a pipe in the bottom for air flow. I was wondering what I should line it with, I was thinking a mix of silica sand and fire clay but I don't know a good ratio. 

Any suggestions?

Expecting something different by asking essentially the same thing in a different thread? You really need to practice your amazing Colton, this is really just inviting snide remarks and some of us have to REALLY try not to be snippy. 

Perhaps we should recommend you do some reading in the solid fuel section before making any more suggestions. Hmmmm?
