Cmon man, crystallation and distillation have existed before 6th century. Whom you are fooling around ??? if distillation didnt exist how they use make alcohol, salt for crystallation.
You seem to be a narrow minded and religious cocktail injected to the bone bigot. You are frog in the well and jaundice infected person. Getout of this web of religion see the other man as a human being but not to which religion he belongs.
If every religionist like you becomes a bigot we are going to kill each other to the end. Hypocrites like you have sowed the seeds of hardened religious feeling in others to foment and cus trouble.
You will not achieve nor anyone only the civilisation on whole gets affected. Lastly, you come with no religion stamped on your back until your parents pour it in your heart, mind and soul. If your parents would have told you you are hindu you would become a hindu, a christian a cristian and a muslim a muslim. Stop your blabber of supremacy, let some sense prevail in your mind.
