Wonderful stuff

I use this not only to thin out Document inks but in ink mixing with other brands. (Test a small amount for compatibility before inking the mix in a pen.)

This is a very cool item. I have been having a lot of fun experimenting with it in my inks that I use for my drawings!!!Also I marked it as high in shading because when added it does aloe for more shading in whatever ink I have put it in.... I have only used on the document black and document fog grey in small amounts so far .

Fast Service as Always!

It was great. Just what I was looking for to dilute the DeA inks and to mix new colors/shades.

Does the job!

I wanted to dilute DeAtramentis Document Urban Grey to a lighter shade. Decided to try 50/50 and it was perfect. It's a pencil grey now. This is an excellent solution to the problem as it doesn't change the ink's lightfast or waterproof properties. The qualities marked medium below were not tested but the form wouldn't let me leave them blank.

Love mixing colors

Love the De Atramentis Dilution Liquid. I am a sketch artist and I love the ability of being able to create my own colors with the De Atramentis document ink and the additional option of being able to mix colors and control the darkness of the colors is great! And the added bonus the ink is waterproof. Love it

FAQs about Bottled Ink

Which pens can accept this ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Any of these fountain pens will work with bottled ink. Typically, as long as the pen can be filled with a converter, has a built-in filling mechanism like a piston, or can be eyedropper-filled, it can accept bottled ink.

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.

You can learn more in our blog: How to Write with Shimmering Ink.

My ink smells funny, is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Generally yes! Ink does not smell good- it usually has a chemical smell, along with other scents such as sulfur, rubber, chemicals or even paint. However, as long as you’re not seeing anything floating in the ink, it should be safe to use.

It’s cold and my ink froze; is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes, frozen ink will not hurt your pen (after it’s thawed of course!) The issue with ink freezing is primarily a concern because certain glass bottles could break as the water-based ink expands, and then you’d have a mess!

What is your return policy for bottled ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B
