Ron, if all you need is to see the pattern, ferric chloride is quite OK, and takes about 5 minutes. I've done literally hundreds of mechanical damascus blades, and if you've used the stuff previously, its easy.
Doing a proper, high quality, traditional stain on a keris blade is a totally different ball of wool.
On an old, previously stained blade, it might only take an hour or even less, on a newly made blade, a recent blade, a blade that has required intensive cleaning, a blade with a complex pamor, a blade with unusual pamor material --- and other unmentioned conditions --- the time used to achieve a satisfactory result can amount to quite a bit. I usually allow a day per blade, and hope it won't run into more. If you want a perfect result, then it is definitely going to take longer, maybe a lot longer.
