Hi Anne

I have experimented with tannic acids and have found that they work great for bluing the blades but they really don't make the wootz pattern pop out that much. I usually use a 3 parts water 1 part ferric chloride. This mixture does a good job and the more diluted solution does not corrode the blade. You can use baking soda to help neutralize the etchant after it is applied. I find there are differences in the way certain types of wootz etch. The Indian wootz has a more gray low contrast look while the persian wootz seems more refined and has a more blue/black look to it. I spoke with Mr. Pendray about this and one opinion is that the persians bought the igots from India and some how refined them through forging and heat treatment.

Regards,

Lew
