This afternoon I finally finished a fountain pen, entirely made of iron.
After turning and polishing the parts were dipped in a solution of vinegar, salt and Hydrogen peroxide. To speed up rusting process the parts are warmed in hot water first before dipping. After 14 days, repeatedly dipping and brushing, the rust has developed over the entire surface. The rust partcicles are removed completely with a bamboo stick. Then the parts are boiled in a thick tea-soup for several minutes.
The tannine in the grean tea stopps rusting process immediately and seals the rust surface to prevent of further rusting. This is a technique developed by Japanese armorers and tsuba makers. Today craftsmen add a thin coat of "Renaissance wax" to give it an additional sealing. I have burned onto the rust surface several thin layers of raw urushi (ki-urushi) that have only been rubbed on.
Cap: Length 70.00 mm, diameter 16.00 mm
Barrel: Lenght 115.00 mm, diameter 16.00 mm
Capped: Length 150.00 mm,
Weight: 70.00 gr
Feeding: Cartridge/Converter/Eye-Dropper
