A rainy day in between prevents me from returning after 24 hours and gives my experiment some more time to show results.
Wow! I have not expected such amazing confirmation of my theory that the reaction of tannin with the iron oxide, which is possibly contained in Banyan barkcloth, will produce black discolouration.
Not only am I rewarded with deep black rust stains, even a pattern has formed where the strings have pressed the bark firmly against Edna’s magic rusty rod. This now makes me wonder what would happen, if I wound a freshly beaten strip around the magic rod? I still have some unbeaten bark in the freezer which I will use for that next experiment. How exciting! Watch this space…
