Stoneware is fired at very high temperatures so that it becomes non-porous, almost like glass. The heat literally melts down the microscopic holes until it's impervious. Earthenware is fired at lower temperatures and is porous. It can also be easily scratched and damaged, whereas stoneware resists scratches very, very well.
Stoneware is for all practical purposes
man-made stone. Just with other types
of pottery or china, clay has been formed
into a desired shaped and fired in a kiln to
make it hard and glass-like in its imperviousness
to liquids.
Earthenware, for example, is not
impervious and will absorb liquids. Porcelain
china is said to be a variety of stoneware
although always whiter in appearance.
In its natural state stoneware will appear gray
or brown, but typically glazes will be applied
before firing to make the stoneware any color
the manufacturer and consumer desires.
For this reason, on its surface, stoneware can
be difficult to tell apart from porcelain china.
Some consumers like natural, earth tones that
go well with any color of food and any home décor.
There are also many bright solid colors and bright
patterns available, including ornately hand-painted
designs that rival the finest of china.

Porcelain clay is a very fine material for very detailed and attractive ceramic products. It has a translucent nature and is more expensive than the clay used for earthenware and stoneware. It is fired in a kiln at temperatures between 1,200°C (2,192°F) and 1,400°C (2,552°F). For more information, see 'Related links' below.
The stoneware won't, but if there are contaminants in it they could.
when you bake or "fire" clay, it dries, and begins to melt, There are numerous complex chemical reactions that occure between the various subtances that make up the clay. Depending on the type of clay and the temperature to which it is fired it may be called earthenware, stoneware or porcelain, which are all types of ceramic.

Stoneware is generally heavier than earthenware because it is fired at a higher temperature, making it denser and more durable. Earthenware is fired at a lower temperature and is more porous, resulting in a lighter weight.

To distinguish between stoneware and earthenware, examine the clay's color and texture. Stoneware is typically denser, has a smooth surface, and is often gray or brown, while earthenware is more porous, softer, and usually reddish or terracotta in color. Additionally, you can check for a glazed finish; stoneware is usually fully vitrified and less likely to absorb water, whereas earthenware may be more absorbent. A simple water test—placing a few drops of water on the surface—can help; water will bead on stoneware but may soak into earthenware.
