Pigment TOKYO handles natural dyes color ink by ZECCHI in Florence, Italy.

Kaochinile ink is from Kaigaramshi, indigo blue is indigo, logwood brown is logging, and oak black is all derived from natural.

Furthermore, Arabi rubber, honey, and vinegar are added as glue materials and additives, featuring the gentle colors of natural materials.

Unlike many pigments on the wall of this lab, natural dyes are produced from animals and plants.

The biggest difference is whether it is soluble with the coloring material alone.

For example, even if you drop a pigment on a water -filled picture dish, it will not be mixed.

The pigment is like a colored sand, and it is necessary to mix it with piles such as Arabi rubber and acrylic emulsions to make it familiar.

This is a state of dropping cadmium red on a water -filled picture dish. The pigment does not have the property of dissolving it in water, so it does not become colored water even if it is left as it is.

So what happens in Kochinile? Put the scales, which are the source of the dye, on the plate, and drip the water a few drops.

Then, as you look, the familiar red color oozes out. The transparent pigment not found in the pigment has oozed out.

The whole is immersed in water, and if you leave it for about 30 minutes, it will be like this. At first glance, it is a bit strange that such a vivid color comes out from the seemingly black grain.

In this way, the natural dye has a transparency peculiar to water -soluble coloring materials, but it is not excellent in light resistance, and it is a good idea to apply Varnish to prevent UV after production.

So what kind of color do you actually draw on paper?

This time, I tried a simple trial paint using this ink.

First of all, here is the random ink from the top with a dropper and then extended it with a brush containing water.

Even in the darkest part of the ink undiluted solution, it has a gentle color reminiscent of natural things.

This ink has a low viscosity and is very suitable for creating a smooth gradation like this. Before you use it, shake it well before using it.

Next, I tried to draw a straight line with a groove drawing using SK Stars No. 6 of Namura Taoseido.

Even if you put a brush directly from the bottle, this concentration is this concentration, so it may be more suitable for pale painting expressions using watercolor paper and the like rather than creating a hard edge screen.

It is an expression unique to ink, which has a low viscosity and smooth drawing that keeps a certain concentration even if you keep drawing a long line.

Finally, I used a round pen to draw a narrow straight line continuously.

If you draw with a lot of effort, you can draw a dark line.

This time, I drawn on bamboo shoots (for watercolor painting), which is somewhat water -absorbed, but if you try another paper, you will change the edge.

Today, color inks are evolving in various ways, and various types of products, such as water -resistant pigment inks and scientifically made dye inks, are sold by each manufacturer.

However, using these natural inks used by ancient times gives the work a color that has never been seen before.

Please experience the soft red color that can not be an artificial object.
