I do hsare your opinion about that diffrent blades (pamor technices+material) need diffent aproach. Yes a new blade with pamor neckel/nickel/titanium or something that is pure. Needs a more stong solution, now since that AsS or As2S3 do not solve as good than As2O3(20Gr/l) And trioxide is wtronger to react.. beter to use trioxide. But with old blades as pamor Luwu and Pramamban beter to use less strong solution, realgar does the job good engouh. Just need to give it more time. My experience with realgar is that the solution does need time too to get on strenght.
here some pic of my just finished blade. Hope the pice are good enough
notice the bath on the left.
BTW, this is ther Yogja Keris with the square peksi!
