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. :)

puppet leather part 1 (coloring)

could we connect between culture and science? the answer is yes, but how? let me tell you about our heritage. we have puppet, puppet is one of the heritage ever we have. if want to make dye for puppet leather, we have to measure for each material, for example to make white color we need ancur lempeng, Ca(OH)2.H2O, bone powder of cow, and water. first we have to dissolve ancur into Ca(OH)2.H2O, the function of Ca(OH)2.H2O here is to make ancur softer. because ancur is a protein which can dissolve in the acid or base. but ancient people used base for the solvent. based on the story we can conclude that culture will never be separated from scientific. i really love science but i love culture too. i have a dream one day i want to create  scientific and culture evolve together. i hope :)
