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].

No, clay cannot melt. If it heats up it simply hardens. If you put it in water then it the clay particles will dissolve in the water, but this is not melting.
try looking for the melting point of clay instead, they don't change once its fired.
Yes, clay does melt and every type of clay has a specific melting point.
The melting point of ceramic is ~2000°C
No
Depends on what kind of clay i looked into it and clay is not flammable It will either melt harden or explode. Speedkoyn
Glass is silica (sand) mixed with soda. The soda helps the silica to melt - it acts as a flux.Clay often contains silica, and sometimes quite a high proportion of a clay is silica minerals. It also ususally contains alumina and a variety of other minerals. The particular combination of minerals is what gives different types of clay their indivdual properties.In firing the clay doesn't melt like glass, but some of the compoentes of the clay will melt partially.
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.
Just about everything melts or combusts at high enough temperature. If clay is fired at the correct temperature for the type clay then it's called maturing the clay. It's like baking a cake. It's not batter anymore and it can't be made back into batter. Properly fired clay won't break down into mud again. The chemical nature is changed. The particles of clay melt enough to bond them together then the pot is usually glazed and fired to an even higher temperature to melt the glass like glaze and bond it to the surface of the clay pot. Exact temperature is very important. Too little and you get an ugly pot with glaze that cracks off and too high and it can be a melted, warped mess.
Fire the clay like glass, not clay. The problem with melting glass on clay is the coefficient is different. Glass will craze, (crackle) on the clay. If you want the glass to stay on the clay use high fire clay and fire it to bisque first. The second firing with the glass on it should be fired on a schedule that is suitable for the glass. You can not simply fire the glass up to it's melting temperature then allow it to cool without controlling the cooling rate. You may want the rate to be 60ºF/hour to cool depending on the type of glass you are using.
Sand melts ice faster because it has salt and the salt makes it melt alot faster than clay.
They melt into mushy clay substance and remold into another shape and harden.
Do you mean clay triangle? This is used in the Chemistry Laboratory for holding a clay crucible when heating substances to high temperature to melt them.

no, it dries up

There are many products that can be used to melt ice. One is a clay cat litter. It will quickly melt snow and ice in the wintertime.
No, if you are talking about the ones built during the construction skill - then definitely not.
clay acts as an insulator because its an non-metal and there are no free electrons in it whereas cooking untensils are made of metals with free electrons therefore they can conduct the heat unlike clay :) + the clay will melt if it was over heated
You can! but be careful what to use to handle the marble.
A combination of both. The clay minerals partially melt (physical), and react with each other and the oxygen in the kiln (chemical)
