The pieces must be placed in a way so that no space is left between them as far as possible. In order to fill the possible gaps between Persian Turquoise pieces, temperature is added (to about 40o C) and some more shellac powder is sprinkled onto the pieces until the shellac layer is softened to a melting form, and then try to fill all the spaces by adding smaller Persian Turquoise pieces, or, as they say, the pieces sit well on the surface. This is usually done by pressing Persian Turquoise pieces by hand onto the surface so that they stick fast to it. After the object is cooled, the shellac covered parts become rigid. After that stage, the parts covered by shellac and Persian Turquoise pieces are polished with emery so the extra shellac and little raised parts of the pieces are flattened.
