Winsor & Newton Watercolor Medium, Gum Arabic, 75ml (2.5-oz) bottle

Winsor & Newton Gum Arabic, 75ml I'm starting with the product name because the reviews on this page seem to be for a mix of different products. I started using the gum arabic for mixing up inks with Pearl EX Powder Pigments. They make beautiful pearlescent product that can be painted onto paper or canvas. I use them for writing with calligraphy dip pens. They look great, but if just mixed in water, the Pearl Ex is not durable and will smear off. Gum arabic to the rescue. It fixes the pigment on paper after it dries completely. Gum arabic can be rather gooey. The amount used should be controlled carefully. (I use 1/4 tsp to 1 tsp of water most of the time.) It's best to let the finished product dry completely before handling. I find the liquid gum arabic convenient to use. It's also handy when I want to add a drop or two to adjust properties of ink. Oxygen will cause it to go bad over time, so I minimize exposure to air. As it ages, it will turn more yellow. I like the shape of this little bottle. I normally use a blunt-tip syringe to transfer the liquid, but it is easy to pour from this bottle. The cap seals well and doesn't leak.

Daughter is using at school in an art class, she says it's perfect and at a great price.

I know it seems costly for a small bottle of Gum Arabic. But you must consider that the tree sap this is made from is a lengthy process. It is a natural product grown in few places. Secondly is that it has been made into liquid form, which as someone who makes homemade watercolors is easier when mulling mica or pigments down. Last is it will last for so long and Windsor & Newton is a high end historical company. I will buy if I indeed do run out.

I only use this for shaping clean oil brushes, and it's great for it. It won't restore a very worn brush unfortunately. It'll just keep it from splaying any further.

Someone in my calligraphy group recommended this for helping my colored inks flow more smoothly. I find it does once you find the right balance. Would definitely buy again. The lightening fast shipping was deeply appreciated! Thank you!

Seal the envelope with it Winsor&Newton gum

I decided to make my own shimmering water color from mica powder and this gum arabic. It worked GREAT and was fun to use to make my own colors. The results were perfect, and the smoothness of the paint is outstanding.

Better price than art stores...beginning to prefer this to masking fluid. (I use 3M packing tape for larger areas. Works great.)

This gum Arabic works very well for mixing with the pigments in the Pearl FX mica. It mixes very well and sets you up with a lovely source of watercolor mix that can be refreshed with a bit of water.

Very happy

great product! worked well to bring back the point on my brushes
