On historic aging

Your guru is right. If your intents fall under historical accuraccy, dont use the suggested winsor cracking medium. Also Keep in mind that liquin is a product origenally developed for commercial alkyd. Meaning its compound is rather new in art.As a general rule I would recommend changing your medium to a combo of linseed and poppy. Poppy is a more brittle medium so will be more succeptible to crack. Black walnut oil is anouther traditional medium more brittle than linseed. So I would begin with a fifty fifty mixture of linseed and any of the other oils. then take an old soup can. Add about four table spoons of Damar crystals. After wards fill about a quarter of the can with acetone and two quarters gum turpentine. When this is done put the solvent compound in a glass jar with a metal lid. Remeber acetone evaporates very quikly - so keep the lid on it.When your ready shake the jar of oil lightly and shake the jar of solvent lightly. Then mix the two equally, this will make your base medium. Keep a lid on it, and remember this is a base recipe - which my require alterations in accordance to your projects. Anouther tip--------When you cook the painting - make sure it is dry to the touch, a minimum of a week - or pockets of moisture will develop in the paint film.Get a copy of the Artist Handbook it will tell you every thing you need to know about proper chemistry, pigments, and conservation... It is a classic and is updated by Yale every 10 years.Good luckPell
