Marbles come in two distinct types, namely glass and ceramic. Of the two, glass marbles are more popular in the market. Ceramic marbles are once more popular and inexpensive to make. They are often crafted from surplus crockery or leftover clay. The extra clay is extracted into metal molds of different sizes. These molds are placed into the industrial kilns and they are fired. Newly tampered marbles are tapped out gently of the molds and dipped in several glazes. The glaze provides protection to the ceramic marble from early cracking as well as outright shattering. The marbles that have been glazed are fired at very low temperatures and solidify the glass-like shell of color.
There are to methods used in producing marbles, by hand or the use of machine. The most affordable ones are machine made. These marbles are born as clipped globs from molten glass that is taken from leftover industrial products of glass. The globs are spun through the corkscrewing cylinders length that spins them into almost perfect spheres in different sizes. The color is then injected into the kiln or clear glass streams for they are cut into globs. When the spun spheres cool, they will then be sieved and then shipped off.
Hand made glass marbles are more expensive than the machine made ones. Typically, glaziers stack colored glass rods and glue them to single rod of clear glass. The rods are forced into the furnace until they become read hot. Then quickly they are twined against the newspaper that is wet and shaped slowly into thicker rods. The glazier will repeatedly perform this process as many times as desired to add color. If the colors are already in place, the formidable rod will be stretched and then the glazier will notch the end continually in order to form a sphere.
If the sphere is almost completed, the glazier will now set the rod and tap off the end carefully with a sharp blow. Then the residue will be removed with the aid of a torch and the newly made marble is fired into the kiln to provide strength into it.
