People generally don't use them because they build salt, they obsorb water, and they get hot. VFT as we all know like to stay wet so a clay pot would always hold water. My hydrangea was in a clay pot and algae grew on the sides of the pot in less than a month! Very gross.
Glaze is used like paint and it comes in different colors. When you are done painting you put whatever you want to glaze into a kiln. My art teacher has one and I think it cost Ū,000. Unless you plan on mass producing glaze pots, I recommend you just buy glazed pots from the store if you want to use them so badly. But glazed pots still heat up, so forget about growing plants in full sun.
Bottom Line: Plastic pots are the best.

If you REALLY want to use the clay pot, how about lining it with plastic as you suggested, but with no holes, and use it as the water tray, and put the plants in a smaller plastic pot sitting in the larger clay one.
I personally loathe plastic (unless its 1950s plastic!), but I finally had to bite the bullet and use them. Plastic pots do seem to work best with CPs, but you can also use glazed ceramic as it will retain moisture. If you use unglazed clay pots you will be watering watering watering watering...lol...as the water will evaporate fast!
