Granulating Solution & Medium for Watercolor

Granulating Solution & Medium for Watercolor

Hey Art Friends! Welcome back to the Mandakyns Channel!

Today’s episode is about an experiment I did where I dissolved various salts in water by super saturating the water and then straining through a coffee filter. Using this method, I created my own granulation solution/mixture.

I show the various effects that each of my salt solutions:
*dead sea salt
*iodized salt aka sodium chloride or table salt
*epsom salt aka magnesium sulfate

had on ultramarine blue watercolor pigment applied to strips of watercolor paper.

Then, I did a fun experiment where I added a substantial amount of pigment to a fresh solution of epsom salt in a spray bottle and tested it by itself and the effect each solution had on the watercolor pigment. I got some awesome and interesting effects with these sprays.

This is a really great and inexpensive way to create your very own granulating medium! If you like granulating effects in your watercolors that you play around with making some solutions that you can easily make with household items you likely have around your home!

As far as I could find, the product has been discontinued from Winsor & Newton and I could not locate it for sale.
I think being able to make these products at home and sharing these recipes conveys massive amounts of value to my audience. Therefore, I decided to compile all of my recipes into a book project that I am currently working on.

IMPORTANT NOTE! Be very careful not to contaminate the watercolors in your palette! Keep a jar of clean water handy and another for dirty water! Always only use clean water in your pan watercolor palette to keep your watercolors from getting dirty, mixed with other colors, or from having other contaminants (like the salt from our experiment) destroy your watercolors. Always allow your paints to dry after use, they can easily be reactivated. Storing watercolors with wet paint in a warm, dark place can cause mold to take root and destroy your watercolor pigments.

However, I would also set aside a paintbrush for this as salt may be corrosive for your ferrule (the metal part that holds the hairs of the brush) or could possibly damage the glue that holds it together. You should never leave your brush in the water for long periods as it can cause damage, but especially this water as it will be corrosive over time. It might be a good idea to mark the handle of your paintbrush with washi tape and permanent marker “SALT” if you will have trouble identifying it later.

MY ADVICE: Keep a separate dish or palette for these types of adventures to prevent mixing any solution with your beautiful watercolor paints. Tube paints worked best for this experiment so that I didn’t accidentally go into my pan colors with salty water to get them juicy and inadvertently contaminate them. Once you add salt to your colors it will change the behavior of the paint, therefore it is a good idea to keep them separate.
