Frankly I think you are fooling yourself my friend. You obviously have no idea how tuff that porcelain is. On a MOHS Hardness Scale it probably has a hardness of around a strong 7 or maybe 8, diamonds are 10.
Even if you were to add a diamond blade to your collection and even if it were one of the "dry cut diamond blades" you would quickly burn the blade and ruin it without a constant source of cool water.
I'm sure the Avaire guys know exactly what the hardness is and I'll bet I'm not far off.
Rent a wet saw.
