There has been some discussion recently in Fountain Pen Geeks about vintage inks of which I have several. I use most of them. One or two have been a sad failure through settling out and though I’ve tried mixing them and even boiling it has been impossible to return them to their original strength. Luckily all the others are as good as they were when new.
This Swan Blue/Black ink bottle was full when I bought it some years ago. It has been my go-to ink ever since. I decant it into my normal-sized elephant bottle.
Some feared that old inks would have mould and maybe some do but not any of mine. If the cap is secure the inks should be free of mould. I think that mould is more of a problem in modern inks.
Anyway I take a special delight in filling my Swans with the ink that was intended for them.
(I managed to include our Peugeot 3008 in the background. Aren’t modern cars boring? Reliable and durable but boring.)
