I have done the warangan process a few times on some of my keris with varying results.While i am sure a professional would do a much better job i just did not find it practical to send any of my keris abroad for staining as well as the worry about loss or theft along the way when sending the blade numerous times over great distances to foreign countries. I was fortunate to be able to obtain some lab grade arsenic trioxide some years back and though i have never had any training in handling such material as Alan suggests i treated it with the utmost respect and care and believe i handled it all pretty safely.
I used the brush on method that was described by Alan on this forum some time ago.
I have learned a few things since that i believe might make the procedure even more successful the next time i try it, but i suppose that remains to be seen until i make the next attempt. But while it is a slow and perhaps tedious process to go from a rusty dull blade to something that presents good colour and pamor i don't think it is difficult to be able to at least improve upon the appearance of a keris if you follow simple directions. I do find the videos presented by Milandro to be rather drawn out and overly complicated using methods which seem unnecessary from what i have seen and experienced.
Here is a Bali keris that i stained about 13 years ago. When i found the blade it was not in the best of shape. It had lived in a store window of a curio shop in South Orange, New Jersey for some time and was covered in a thin layer of active rust. The first group of photos shows the keris after i cleaned the rust off with a soak in pineapple juice and regular scrubbings for a couple of days and then gave it a warangan treatment. I must admit that i did not use Tahitian limes, but rather whatever regular limes were available at the supermarket. As described before, i used lab grade arsenic trioxide to make the warangan.
As you can see, my first treatment was weak at best. It was certainly an improvement over the original condition (sorry, i didn't take any before photos) and revealed the pamor pattern, but it was not satisfactory for me. The second set of photos (sorry for the quick and poor cellphone pics as i did not photograph this at the time and just made these now for this post) shows my results from may second attempt on this blade done soon after the first. It is still far from perfect, but i decided not to make another go at it and to live with it as is. The stain seems to have help up well over the more than a dozen years since it was applied.
I do have a few blades i have been wanting to attend to for some time and maybe i will get around to them this year as the weather improves. If i do i will be sure to document the process for thoroughly.
