Please take note of the previous suggestions to decant the ink into at least two [glass] bottles, which was refined to propose three bottles - taking into account the large volume, avoiding sediment and keeping the ink sound as time passes. http://www.fountainp...ost__p__2164772

I thought I'd add a bit of feedback (no pun) about ESSR. I picked up a bottle of this a few months ago, and was using it exclusively for most of that time, being swept away by enthusiasm for it. Have run into a small issue that has caused me (at least temporarily) to get swept away by another ink. That's me. All or nothing.

Of course, it's a great way to really get a feel for an ink - use it all the time, in all my pens for a few weeks, and I will get to know it pretty well...
Great things about ESSR, which I still LOVE - it really resists bleedthrough and showthrough, even on relatively lousy paper. That is COOL. It shades nicely, especially with a wetter pen. It morphs from blue black to gey-black with a hint of blue. Cool. I like that. It is permanent and waterproof. Love it! It is well behaved and looks good.
But - and this is why I re-posted your comment above, Sandy1 - I did find that if I wasn't absolutely rigorous about pen hygeine, cleaning out daily after use, the wetter pens slowly became medium, then dry. Further, is stained the heck out of my Pelikan M600 & M605 ink windows, and any converters I used it in (the satins resolved rather well with lots of flushing and leaving the pens loaded with water for a few days). Now, this may be ameliorated by filtering/decanting the ink so that there is less sediment, but really the only way to avoid it well would be strict flushing after use. That's a pain, to me.
In the balance - I still really like ESSR, and am more than glad to have a nice big bottle of it, and WILL continue to use it with the cautions above. But for now, I am on to Lamy's Blue-Black Iron gall ink, which doesn't seem to clog as much (so far).
OK. Back to work.
