Manufacture
Manufacturing depends on the raw materials, their ratios, fluxes, temperature, atmosphere and reaction time.
Production seems to have been focused in northern China, around 200–300 km north of the city of Xian. This is the area with large deposits of raw materials. There are no written records about the production of Han purple or Han blue and so information about manufacture has been achieved through experimentation.

Famous quotes containing the word manufacture:
“Yes, that’s what I needed. Living flesh from humans for my experiments. What difference did it make if a few people had to die? Their flesh taught me how to manufacture arms, legs, faces that are human. I’ll make a crippled world whole again.”
—Robert Tusker, and Michael Curtiz. Wells (Preston Foster)
“The profession of magician, is one of the most perilous and arduous specialisations of the imagination. On the one hand there is the hostility of God and the police to be guarded against; on the other it is as difficult as music, as deep as poetry, as ingenious as stage-craft, as nervous as the manufacture of high explosives, and as delicate as the trade in narcotics.”
—William Bolitho (1890–1930)
“The great cry that rises from all our manufacturing cities, louder than the furnace blast, is all in very deed for this—that we manufacture everything there except men.”
—John Ruskin (1819–1900)
