For those who don't know diemticona is a medicine that is basically a "detergent".

After using a bottle of Parker Super Quink Royal Blue(vintage) with solv-x I had the idea of adding some drops of dimeticona to a bottle of ink just to try...so I added 10 drops of dimeticona to my 2/3 waterman black 1/3 pilot ink blue(I don't like it but mixed it is fine) .... it increased the flow pretty well and I started to like very much this receipe...and then I had the idea of adding some drops of
violet watercolor to improve the "reds" I added and the ink its awesome!

....there's any problem in doing so?

Im beware of the detergent problems in piston fillers(taking the lube out of the piston)...

Is this what we here in the US would call Dimethacone?

if so - it's used a lot in hand lotions I think.

hmm.. seems to be a silicone derivative... which sounds like it would be rather "unreactive" but... since it is used to help lotions and shampoos adhere better to your skin/hair/scalp... it might not be the best thing for the pen.

OTOH - it might be "coating" the surfaces thereby altering surface tension and allowing the inks to flow through better.

would love to hear a chemist's POV on this!

Hi Dvenosa,

I would be a little worried adding watercolour to an ink. As far as I know, watercolour is pigment based, and hence not so good for fountain pens. Better keep an eye on it, making sure it doesn´t dry out in the pen. And also make sure you rinse out the pen thoroughly when done with this colour, to make sure all is removed before using another ink.

It´s ok for dip pens, no problem.

some folks do use watercolors in their FPs. As wim said, just make sure it is cleaned thoroughly and not allowed to dry out in the pen. I'd recommend reserving this sort of mixture for cheapie, easily replaced pens if you're going to use it at all.

I have to say - I think the 51 collector would be more prone to clogging with pigments than many other types of feeds. But perhaps Richard B. can weigh in on that comment since I really only know the bare minimum about the 51.

I use watercolour on a daily basis (as some poor unfortunates around here will testify) but I've seen what happens to raw pigment - it dries to a kind of gluey goo. Logic tells me that I wouldn't be brave enough to put this into any FP I cared about.

Im using just a few drops of watercolor...and im talking about the liquid one not the one in "tablets" .... and I think silicone can be many things and not necesseraly sticky, for example: silicone grease...that acts like a lube

Hi Dvenosa,

Just trying to help. that's all...

Please do make sure that it isn't a water colour with pigments. All of the ones I know, including the bottled ones, are made from pigments rather than dyes.

Unless you mean colours like Ecoline and the like, as those are dyes, and they can indeed be used in fountain pens.

HTH, warm regards, Wim
