Hello guys, I'm back at it.  Does anyone know how I can determine how thick I need to make a bisque fired terra cotta wall to hold the pressure of the liquid contents inside?  Of course I'm not making the huge qvevri that they made in Georgia and had to be buried, still might try for a 30 gallon vessel.  This is assuming my seams and good, walls consistent, my recycled clay was clean etc.  And also, I'll probably end up pit firing because of the whole size of the pot kiln situation.  The shape will be a variation of the classic qvevri, round with high and wide hips, but probably not so exaggerated.  And it will be sealed with beeswax.   As always I appreciate your wisdom, input and encouragement.
