Winsor & Newton Gum Arabic: 2.5oz

I84. Winsor & Newton Gum Arabic. 2.5oz (75ml) glass bottle.

Gum Arabic has many uses. This solution can be added to inks and gouache as a binder, making them more easy to use for calligraphy. It increases gloss, color brilliance, and transparency when added to watercolor. Gum Arabic also slows down drying time, make it easy to control the spread of wet color when using wet-on-wet techniques.

Add several drops to a bottle of Higgins Eternal for copperplate writing. 

I have worked with metallic gouaches for many years. I always add a little more gum Arabic if there are going to be lines to erase, then allow the writing to cure for several hours before erasing. A white vinyl eraser is the gentlest choice for erasing guideline. I avoid guidelines if possible via a light box. -- Don King
