clay has a chemical in it that absorbs water.So it holds water well.But it will not drain fast.
Melting point varies based on the minerals that compose the clay(???), and firing time seems to be just as important[1]. Try to find out the composition of the specific type of clay you're using, and ask local potters and suppliers. Prepare a sample and ask a kiln operator to fire it, checking occasionally to see how the clay is reacting.During the firing process, the clay is gradually heated through various stages of chemical change until the particles begin to melt and fuse together (vitrification)[2][3]. It has 'matured' when the clay has reached its highest density before beginning to deform. Over-firing can actually reduce it to a puddle.The firing process can be monitored using 'cones', pieces of specially mixed clay that begin to melt at specific temperatures[1][4].[1] http:/pottery.about.com/od/temperatureclayglazes/tp/pyrocones.htm[2] http:/www.wingedblue.com/conechart.html[3] http://z.about.com/d/pottery/1/0/b/0/-/-/tempclay.jpg[4] http:/en.wikipedia.org/wiki/Pyrometric_cone
Firing clay is when a clay is fired in a kiln, this is to make the clay stay strong.
a clay slab is a slab made of clay
Clay is made of clay ...
Sixth Stage: Vitrification and MaturityThe maturation of a clay body is a balance between the vitrification of the body to bring about hardness and durability, and so much vitrification that the ware begins to deform, slump, or even puddle on the kiln shelf. Vitrification is a gradual process during which the materials that melt most easily do so, dissolving and filling in the spaces between the more refractory particles. The melted materials promote further melting, as well as compacting and strengthening the clay body.It is also during this stage that mullite (aluminum silicate) is formed. These are long, needle-like crystals which acts as binders, knitting and strengthening the clay body even further.Please see related link for a complete explanation and all the stages!

He writes about vitrification in one ancient city in India. There is lack of agreement of the age of this city among the archaeological community. He writes that he discovered vitrification and an epicenter crater close to the village.
Vitrification is a process where a substance is rapidly cooled to form a glass-like solid without crystallization. It is commonly used in cryopreservation of biological materials, such as embryos or tissues, to store them at low temperatures without damaging their structure.
Sinterization is a process in which pieces are fired at a temperature sufficiently high to achieve a certain grade of vitrification without achieving complete fusion of the clay paste used, cementing the clay particles together in such a way that the piece takes another colour, loses porosity and achieves a wrinkled texture.
Vitrification in plant tissue culture refers to the abnormal formation of a glassy, translucent appearance in the cultured plant tissue. It is often caused by excessive levels of plant growth regulators, high levels of sucrose in the culture medium, or suboptimal environmental conditions. Vitrification can negatively impact the growth and development of the plant tissue, leading to reduced regeneration potential.
Vitrification is the preferred method for the cryopreservation of gametes. It involves freezing them quickly so that ice crystals do not form.
Technically vitrification, though that word also has other meanings than specifically a liquid becoming a glass.
