How Granulation Medium and Water Colour Medium work and how to use them.
Granulation Medium - A medium that is known for giving a mottled or granular appearance to colours that usually give a smooth wash. For maximum effect, dilute colour with medium alone.
Water Colour Medium - Now discontinued, Winsor & Newton recommend Ox Gall Liquid as an alternative. "Ox Gall liquid has same benefits as Water Colour Medium i.e. it is a wetting agent that can be mixed directly with water colours to improve their flow. It also has the extra ability to handle acidic colours e.g. Ultramarine, and can be used on very hard sized papers to reduce surface tension."

SO HELPFUL. Quick question, why can’t I use with ultramarine?

@JacksonsArtSupplies 10 лет назад

yes I think you're right Renee, it sounds as if it may have gone off. It may still perform to an extent but chances are the structure of the aged medium will not be how it should be and will impair the results of your painting.

excellent video, I appreciate your efforts and great info.

You are correct, Winsor have now discontinued this Water Colour Medium. On their website they recommend Ox Gall Liquid as an equivalent... "Ox Gall liquid has same benefits as Water Colour Medium i.e. it is a wetting agent that can be mixed directly with water colours to improve their flow."

Brilliant idea, ideal for Plein air

@michaelklein5242 Год назад

Thanks for the demonstration! It sounds like the second medium/additive you bring up is gum arabic? Much appreciated! 🎨

I love it

Will it still granulate after drying on the palette and then rewetting with water for the next painting session? Or do you need to rewet with more granulation medium?

@JacksonsArtSupplies 2 года назад

Hi there, thank you for your comment and question. As the medium essentially separates the pigment and binder, potentially you wouldn't want to come back to it after you have finished painting as you might find it has separated too much and becomes unworkable. Realistically if you just add water to rewet, it will in essence dilute the granulation medium further and so the strength of colour will also be diluted. We hope this helps, all the best, the Jackson's team

@raseshrao3559 7 лет назад

would the granulation medium harm my series 7 brushes ( like the masking fluid does ) .

@ZuckerWatte2311 6 лет назад

no, it does not harm the brushes

+Adam Van Meter Sounds like Ox Gall liquid. It should be fine.

So I have a bottle of this watercolor medium I found in my dad's old art supplies. While I'm definitely the first to open it, it's brown and smells REALLY STRONGLY of vinegar. Is this still okay to use? I'm guessing it's about fifteen to twenty years old.

Using granulation medium

@jcmamet 2 года назад

I am disappointed not to hear mention of the difficulty washing the medium out of the brush! this should not be used for plein aire painting as the medium will only come out of the brush with soap and vigorous washing.

@viridian4388 Год назад

I don't see the point of using the granulation medium for *already granulating colours*, but yeah sure, you do you. Use it on non-granulating colours and then I will be impressed.

@fyrecat1 9 лет назад

Grainy texture an be achieved simply by using cheap watercolours.

@JacksonsArtSupplies 9 лет назад

An interesting thought! The mediums will offer more stability than the cheap watercolours...the graininess from cheap watercolours is caused by inadequate grinding of pigments and insufficient binding with gum arabic....I would be wary of colours retaining their strength on the work.
