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 :)
