Which is better stoneware or ceramic?
Stoneware: less porous than earthenware, stoneware is also more durable and has a lighter color (but is more opaque than porcelain). Porcelain: is the non porous option of ceramic. It has an incredible durability resulting from the high firing temperature. Porcelain is also resistant to microwave, oven and freezer.
Does ceramic crack?
Pottery fracture results from stress within a ceramic body due to thermal expansion and contraction, shrinkage, and other forces. Poor drying or uneven compression and alignment of particles can result in low strength.
Does stoneware scratch easily?
Stoneware. It is more durable than earthenware. It is less porous and is made harder by vitreous (glass) material added to it for strength. It is more opaque than porcelain, and its dense body resists scratching better than earthenware.

Firing pots in any indoor stove is never recommend. It may cause a house fire. The temperatures needed to fire clay are too hot (1,000 F degrees and hotter). This temperature would make any stove red hot and it would exceed the safety designed into any stove.
