I want to buy some ESSRI. Is it a bad idea to buy, say, a year’s worth at a time? I know the cool-and dark bit, I’ve used Diamine Registrars for a few years, but it’s easy to get, so I’ve always just bought one or two at a time, 100ml. I’d like to buy several bottles of ESSRI, but I don’t want it to go bad and throw away good ink money.
It seems to be a pretty small operation - maybe you could just write to the ESSRI people and ask them? I confess that I purchased a bottle years ago but haven't been using it for the last couple of years. I decanted about half into a Montblanc "boot" and it sits on my desk. I'll give it a try and let you know what I find out.
Are they really so different that you would want large stocks of both? I would just carry on buying a couple of bottles at a time of whichever one you prefer to use over a reasonably short period.
They both eventually change colour when written with because of the IG content, and I can't help but think the IG in the bottle would change over a couple of years.
I would say, let them maintain their stocks in the very best condition, and buy it as fresh as you can. :)
I've had the same bottle for over three years with no untoward effects or deterioration so far. Used it this morning to address some envelopes.
Does this affect the viability of the ink? Or just the color?Quote:

It's really a solid product.
I think the ink is generally good, but there is an insoluble precipitate that collects at the bottom of a bottle over time. The advice to decant or otherwise not shake ink before filling a pen is based on the behavior of inks like ESSRI.
When researching historical Iron gall inks, I came upon several recipes and how to keep the homemade inks safe for later use. They recommended to blow in a bottle, before closing it. This way all left in the bottle would be carbon dioxide. I don't know if this is necessary to do with modern Iron galls inks... But it can be a solution :)
Less than 5% of exhaled breath is carbon dioxide. There is three times as much oxygen, with rest being nitrogen (with a smidgen made up of several other elements).Quote:

I submit the advice to blow into the bottle to replace oxygen with carbon monoxide is of limited value. I prefer filtering and decanting such goods into a smaller container to limit exposure to air (oxygen, nitrogen, carbon dioxide and pollutants).
I do this all the time with leftovers in the refrigerator (maybe without the filter).
Fred, I was just sharing an information I found interesting concerning historic Iron gall :)
Sounds more like a job for Bloxygen.
So treat your ink like a bottle of fine single malt. Decant or use it up quickly.
