Hello all,
I have created an immersion suspension tube from 3 clear plastic drink bottles and Selley's All Clear Sealant. The clear plastic tubes will enable me to take pictures showing the in process effect of the juice on the blade.
The tube is sitting in a clear plastic container just in case a leak develops.
The keris fits into the tube and can be covered entirely by juice, I especially wanted the peksi covered as it appeared to have the most rust.
The amount of juice used was around 1.7 litres, the length of the keris is approx 18" (45cm). I noticed after the first couple of hours a kind of settling effect on the juice with the top 3" (7cm) noticeably more transparent.
