Making Paint Mixtures With Titanium Dioxide for Art.

Hello.

I have discovered that Rit Scarlet, Rit Golden yellow, Rit Green, Rit Purple, and other dyes like Malachite green, Sodium fluorescein concentrated, Rhodamine b concentrated, etc can be mixed with Titanium dioxide to form a paint-like material for art.

I recommend adding tween 20 or glycerol to avoid causing the paint to shed a bit (it a very small issue, that may be avoided with tween 20, or soap detergents.)

We will be using paintbrushes made from wood fiber which are cheaper and easier to work with than acrylic fibers.

Warning: Rit dyes are toxic, Malachite green is an irritant and is toxic, Methylene blue and ethanol crystal violet is an Irritant and is toxic. Handle with care. Titanium dioxide dust should not be inhaled. Low toxicity but Irritating to lungs and mucus.

Hot acetic acid is irritating and its fumes are not nice to inhale.

Chemicals and dyes:

Rit Scarlet Red.

Rit Navy Green.

Rit Purple.

Rit Golden yellow.

Sodium fluorescein 25 percent.

1 percent Rhodamine b.

Malachite green. Mine was aged you may get different results with the new MG.

Methylene blue dye 1 percent.

Crystal violet (ethanol-based) 1 percent.

Potassium ferricyanide

Iron ammonia citrate

Iron(III) chloride - Prussian blue making.

Titanium dioxide.

Acetic acid Hot. (Optional).

Supplies:

50 ml beakers or something that can measure 10 to 25 ml of volume for dye.

Scale to Measure out 4 g of TiO2 (Titanium dioxide).

Small 144 ml cups with lids from Amazon.ca.

Pipettes.

Larger 400 ml beaker to keep paintbrushes.

Paintbrushes.

Optional (Hotplate for acetic acid).

It is very important after painting with the (Titanium dioxide dye mix) to clean the brushes in hot water for a few hours and drain and put the brushes through hot water again and repeat the process. Impure brushes may contaminate your pigments.

Here a video on how to use and clean your paintbrushes on Youtube. Boiling vinegar should be done in a well-ventilated area.

I could not find anything with wooden paint strips but acetic acid and other stuff that could be done with acrylic could be done would wood fibers too.

You, if you use acetic acid 5 percent, must be careful and rinse the brushes with tap water in a sink afterward. The acidity may damage the glue fibers of the wood. This precaution is needed to prevent damage from occurring.

Theory on How Titanium dioxide (TiO2) mixes with paints.

There are two types of TiO2 mine that is water-soluble it depends on the particle size.

With a 50 ml beaker clean, add 10 ml of dye to 4 g of Titanium dioxide. The scale saids 3.6 g but I added 0.40 g extra to give 4 g.

The percentage of TiO2 in the dye can be calculated by x grams Ti02/TiO2 + ml dye.

Rit dyes are 10 ml. Assuming 10 ml equals 10 g (Mostly water).

So 4 g / 10 g + 4 g = 28.6 percent for the Rit dyes.

We add 10 ml of dye to these plastic cups and then add to each dye the Individual Tio2. Close the lid very tight and shake (ensure the lid was closed very tightly or it will spill all over the place when shaken!).

Yeah, the Rit Navy green will be also added to show it turns grey sorry for some of the confusion.

We measure out 20 ml of water for Methylene blue, Malachite green, and Crystal violet and add 5 ml of the dye then we add that to a container labeled (Dye**) and add 4 g of Titanium dioxide.

X g TiO2/ Dye + TiO2.

4 g divided by 24 g = 16.66 percent TiO2 for the Methylene blue, Malachite green, and Crystal violet.

All these dyes stain badly wear gloves etc when working with them and eye protection.

For Malachite green add 5 ml by pipette into 15 ml of water and add 4 g of TiO2 (Titanium dioxide).

10 g of Prussian blue liquid with Ti02. And mix.

To 100 ml of water, we add 25 g of Sodium fluorescein and then shake the closed bottle and add 20 ml of that to a cup labeled Fluorescein Dye and add 4 g of Titanium dioxide. Then we close the lid very carefully and shake to make a paint mixture.

Extracting two markers with water with gloves we squeeze the Pink (Rhodamine b at 1 percent) into the beaker and add 300 ml of water and add to a bottle. We pour 20 ml of that concentrate into a cup labelled Rhodamine b paint and add 4 g of Titanium dioxide.

Next, I will explain the paintbrush techniques used to paint paper.

Here are some videos on Painting techniques. Enjoy.

You can use any techniques above to clean and paint with the paintbrushes and the TiO2 dyes. I have one light-sensitive Prussian blue citrate I will show how to make a concentrated solution with it right now. Mixed with TiO2 which should block UV from changing it from green to blue (It does not) it easy to do with and is unique,

10 g of Iron ammonia citrate is added to 100 ml of warm tap water and 10 g of Potassium ferricyanide (Not ferrocyanide) is mixed in another beaker with 100 ml of water. It Produces a concentrated Prussian blue citrate that I tried with a UV light to change to blue. Too long a process.

All these are interesting painting techniques and work very well with Rit dyes, Organic pigments, and making pigments. As long as you clean the paintbrushes can do a lot.

One of my favs is the Lighting storm and the volcano. The addition of tween 20 may help prevent the Titanium dioxide from clumping up a lot and shedding off the paper (Minor thing).
