This preparation is one that I have used for many years with great results - easy to make and the paint not only moves easily across a variety of surfaces but adds to the lush characteristics of the oil paint.
[I have also used this preparation to make putty medium].
1v of Liquin Original [Winsor & Newton]
1/2v Linseed Oil
1/2v Stand Oil
Blend well - make sure to mark your container/jar with the recipe and note as flow medium.
Using a clean large board [white tile or formica shelving is good] or large plastic plate
Add a cup of calcite to one side
In the centre add your flow medium - a quarter of a cup
[I also make the putty using Stand Oil or When I have cleaned my own oil - refer to the calcite sun oil website - I use that]
Slowly with a palette knife bring small amounts of the calcite over into the oil and work well until absorbed into the oil - continue until the oil looks like putty - it should reach the consistency of chewing gum.
Put the putty into a glass jar and seal with a tight lid.
I use the putty medium in equal amounts- 1v of putt to 1v of paint - it will extend the amount of paint you use and at the same time provide the paint with extra body - if you use the recipe with the liquin as mentioned above you will have the added benefit of the paint drying faster.
Check out both these sites they have some information that the professional painter and visual researcher who is interested in materiality will find valuable.
Rabbit Skin Glue as a Size

Using Rabbit Skin Glue Size as a base - heat till warm:
1 volume = 250ml
1 volume of glue to 1 volume of calcite [* you can add 1/3 v of Titanium White to the calcite: 2/3 calcite – 1/3 TW]
Add the dry materials to the warm glue and mix well until blended
Once the gesso has reached a creamy solution add approximately one teaspoon of glycerine to the gesso – this well reduce the porosity of the gesso, as it is very absorbent.
*When applying the gesso ensure to apply a coat to the back of your board to avoid warping – apply between 4 and 12 coats of Gesso – smooth the surface with a pad of muslin that is damp – apply using a circular motion.
*To seal the gesso ground you can do one of three things:
