Here it is explained the making process of brass frames for aranmula metal mirror.A kowa or crucible made of wrought iron having an approximate capacity of holding 9 Kg of molten metal is cleaned. The pieces of pure chembu (copper), eeyam (tin) and nagam (zinc) are added in proportion. The mouth of the kowa is sealed with clay. An opening lid made of clay, is also provided. Two vertically opposite holes are provided to pour out the molten metal. One of these holes acts as an air vent.
The Kowa us then placed in an open pit furnace charged with burning charcoal. It is then covered with pieces of thondu, as thondu retains the heat. It is heated to about 400 degree Celsius (approximate melting point of brass). The molten metal is poured onto flat surface (usually the ground itself). Once cooled, the alloy is then broken into pieces using a chuttika (hammer). The broken pieces are then inspected for the quality of the alloy. If found satisfactory, then it is remelted. Else more amount of the alloying elements are added. The molten metal is then poured into the preheated mound. It is then left for cooling. Once cooled, the clay mould is broken and the casting is removed. The casting is checked for any deformities. Usually the master craftsman prepares four to five mirrors and polishes them at a stretch. When one gets heated he does the polishing for the next one while the other cools.


To achieve high quality reflective surface the polishing can go on from one to two d
ays. Once the required polished surface is achieved it is then further polished using a piece of cotton cloth. Then final polishing is done using a velvet cloth. The velvet tends to absorb the oil that was applied earlier on to the mirror. Hence, further polishing is continued on another dry piece of velvet.The velvet cloth is placed on the ground and the mirror along with wooden blank is moved in the desired direction. Once satisfactory finish is achieved the disk is just heated to separate it from the wooden blank and the mirror is mounted on brass fame.
