 In order to fill the possible gaps between turquoise chips, temperature is added (to about 40 °C) and some more lac powder is sprinkled onto the chips until the lac layer is softened to a melting form, and then try to fill all the spaces by adding smaller turquoise chips, or, as they say, the chips sit well on the surface.This is usually done by pressing the turquoise chips by hand onto the surface so that they stick fast to it.After the object is cooled, the lac covered parts become rigid.
