- db48x 3y agoA quick search would turn it up, but ok. In the early 1800s a sir Francis John Davis traveled in China disguised as a Mandarin. He discovered that green teas prepared for export were adulterated with tumeric, prussian blue, and gypsum to give them a richer green color. … At each pan stood a workman stirring the tea rapidly round with his hand, having previ- ously added a small quantity of turmeric in powder, which of course gave the leaves a yellowish or orange tinge ; but they were still to be made green. For this purpose some lumps of a fine blue were produced, together with a white substance in pow- der, which, from the names given to them by the workmen, as well as their appearance, were known at once to be prussian blue and gypsum. These were triturated finely together witha small pestle, in such proportion as reduced the dark colour of the blue to a light shade; and a quantity equal to a small teaspoonful of the powder being added to the yel- lowish leaves, these were stirred as before over the fire, until the tea had taken the fine bloom colour of Hyson, with very much the same scent. … If the tea has not highly deleterious qualities, it can only be in consequence of the colouring matter existing in a small proportion to the leaf; … It is possible that the Chinese didn’t know that prussian blue is a poison. It’s also possible that they were using real tumeric!
