Terrecota is ground and mixed with chemicals to form a thick paste (lac reisin compound). This is spread on to a wooden base. Gold is hammered into thin pieces and intricate motifs of flowers and birds are drawn on the sheet. The thin gold foil is stuck to the wooden base by warming it slightly. It is called Thewa ki Patti.
Black paint is spread on it to highlight the design and the excess gold is peeled off.
Glass jewellery boxes, artefact and stunning jewellery is created with Thewa.
The pendants in maroon, red and green colours are very popular. Typically, they are attached to beads made of the same colour.
