Indian Science and Technology in the Eighteenth Century: Some Contemporary European Accounts c25.13

c25.13

I have sent you in the box that contains the machines for cleaning cotton a piece of the cinnabar of this country which is made in masses sometime of 100 lb weight at a single sublimation. I have very frequently tried to make cinnabar by the methods recommended in Europe but I have never been able to procure any so far, as the Indian at one operation. I should be glad to be informed if you wish to know the Indian method of making it...I find, too, that they make corrosive sublimate in this country but I never have been able to see the process.
