问一下一个题外问题,鸟的紫色墨水,是酸性的吗?
Pelikan Violet?有人测过是8.2,不酸,偏碱性,但应属正常范围,非强碱。
以下供参考

1.7 for Omas Blue-Black, Omas Royal Blue, Visconti, Lapis Blue 2.2 for Montblanc Blue-Black, Montblanc Bordeaux, Pelikan Blue-Black, Visconti Turquoise 2.6 for Caron d'Ache Imagine in Blue Sky 2.7 for Pelikan 4001 Blue, Visconti Permanent Blue-Black, Pelikan 4001 Turquoise, Quink Washable Blue, Waterman Purple 2.8 for Caran d'Ache Escape in Caribbean Sea 3.0 for Montblanc Emerald Green, Quink Permanent Black, Waterman Blue-Black, Waterman Blue 4.0 for Sheaffer Brown, Emerald Green, Peacock Blue 5.5 for Caran d'Ache Dream in Blue Night 5.6 for Caran d'Ache Protect in Storm 6.1 for Caron d'Ache Travel in Grand Canyon 6.3 for Parker Penman Emerald 6.6 for Parker Penman Ebony 6.8 for Herbin Green, Omas Vespucci Red, Parker Penman Mocha, Parker Penman Sapphire 7.2 for Omas Permanent Black 7.5 for Parker Penman Ruby; Pelikan Brilliant Green 7.9 for Rotring black, Waterman red, Caran d'Ache Explain in Carbon 8.2 for Pelikan brilliant red, turquoise, violet 9.0 for Sheaffer jet black
