puppet coloring using raw and cooked ancur

there are 2 kinds of ancur in the process of puppet leather coloring. first raw ancur, ussually raw ancur used to fish gelatin. fish gelatin should be mix with carbondioksida solvent. the function of Ca(OH)2.H2O is to make gelatin more smooth. after that we mix the solution with kind of color we want. but the raw ancur just hang on till 12 hours after mixed. second, cooked ancur. to make cooked ancur, we have to mixed ancur mutiara or ancur otot which made by cow's bone. then cook in the medium fire until the ancur dissolve in water. after that mixed with color. usually the preservation of cooked ancur longer than raw ancur. nevertheless, the quality of raw ancur is much better than cooked ancur.  that's way the craftmen prefer raw ancur to cokked ancur. :)
