Thank you for your words
Unfortunately windows of opportunity for this particular staining process are not frequent. I will be patient. I will find staining thread with search again. I have Freys book. I believe it to be laboratory arsenic trioxide. It produces black? I will check with source, thanks for the alert.
What a lovely blade!
The dapor is meaningful in intent/Looks good. The requirements to forge such art are unknown to me. Thank you for sharing
What is this bade dapor called? Is it chengkrong?
The blade I posted does look nice in a Java handle.
