Homemade Dilution Liquid Causes Strange Chemical Reaction?

I've recently purchased a CMYK set of Diamine inks to get started with ink mixing. While I waited for it to arrive, I had made my own dilution liquid from 100ml water (not distilled), 5 ml glycerin, and 0.5 ml dish soap. However, I noticed right away that there were these cloudy looking floaties developing in the liquid. At first I sucked them out with a syringe and used the liquid in ink mixes anyway. I really enjoy pale inks but diluting with plain water tends to make inks too dry, so I thought that this dilution liquid was a great idea. The DIY dilution liquid helped give dry inks a wet and lubricated feel, even after diluting to the point that the colour was super pale.

Well, fast forward a few weeks and I accidentally knocked over my closed bottle of dilution liquid, and low and behold it was FULL of the floaty stuff, which had just settled to the bottom of the bottle. Of course I immediately got rid of the liquid because it was pretty gross and I didn't want that stuff gunking up my pens.

I thought I would try again, this time using boiled distilled water and a sanitised bottle, which would hopefully kill any organisms that might have caused the growth. But even after all of that, I still noticed floaties immediately after mixing up the same ingredients. Even more strange, after letting the liquid sit for a bit, it became full of these small, shimmering flakes which look like glitter. 

My guess is that the floaties and the glitter-flakes are from some sort of chemical reaction between the glycerin, dish soap, and possibly even trace minerals in the water. Does anyone have an idea of what might be causing this sort of reaction? Or better yet, any recipes for dilution liquids that have actually worked? Or is plain distilled water the only way to go, and dryness is an unavoidable consequence? 

 

TLDR; Water, glycerin, and dish soap mix as a DIY ink dilution liquid caused a strange reaction. Wondering what might have caused the reaction and if any successful recipes for dilution liquids exist.

One part Platinum Mixable Ink dilution liquid to nil distilled water should work. ;)

I endeavour to be frank and truthful in what I write, show or otherwise present, when I relate my first-hand experiences that are not independently verifiable; and link to third-party content where I can, when I make a claim or refute a statement of fact in a thread. If there is something you can verify for yourself, I entreat you to do so, and judge for yourself what is right, correct, and valid. I may be wrong, and my position or say-so is no more authoritative and carries no more weight than anyone else's here.

Epiphany, I tried your mixture - dishwashing detergent, glycerin, in tap water. Let it stand for two days - nothing untoward happened. The solution is clear, although I will say it took a long way for the soap (+?) bubbles to completely dissolve.

Maybe the tap water where you are is exceptionally hard? Ours is made by desalination, so it has a very specific composition.

I've tried a couple of recipes, as well as distilled water, and ended up going back to either Callifolio or De Atramentis dilution liquid, both of which just work without any messing around. 

 

I did have a similar problem with floaty bits in a bottle of Anderillium wettener. I would probably choose the soap as the culprit.

I have had the best luck the the De Atramentis solution. I've also found that while glycerin is great, the dishwasher detergents vary a lot.

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

Tap water has a typical regional composition. What you observed could had been a mineral precipitation. More likely it was simple microbiology: glycerin is a delicious food for many microbes which were present in your water. Nothing to be scared of, but if you feed them ...

Btw. 0.5 mL detergent per 100 mL water seems to be a factor 10-100 too much.

One life!

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
