Will Liquin Original overpower the slow drying time of stand oil?
 
I like slow drying medium so I can come back to a painting after a few days and still work wet on wet. To make things easy I pre mix my paints with stand oil and OMS and sometimes some clove oil into small containers.

If I go paint en plein air, I would like to have my paint dry fairly quickly since those paintings usually involve a lot of transporting and I don't plan to add to them at a later time.

If I take my pre-mixed slow drying paint and use Liquin Original while out in the field, will the liquin overpower the slow drying qualities of the stand oil and make for a quick drying paint? Or will it just turn into a sticky surface for a while?

I would like to hear from someone who may know but I will probably just try it for myself to find out.

So you've already mixed a slow drying medium into your (store bought?) oil paint and now you want to add more medium (Liquin) to make it dry faster outside.....that's an awful lot of medium to add to paint meant for plein air painting. Sounds like a slimy mess. And an excess of oil binder means the paint film will yellow more. Who wants yellowed plein air paintings?
Why can't you just use normal oil paint with the Liquin?

I can. The whole idea is just to use the paints I've mixed already. If I spend a month doing plein air paintings, I don't want that paint in the containers going to waste. I know they probably won't dry but this is more of a technical question.

Add Cobalt drier instead of Liquin.

I will second that. You only need to add a tiny bit of CoZiCa or some other dryer to your existing paints to speed up the drying process. I bought the CoZiCa because it was less expensive than other brands and it works as advertised. That being said it might not take much alkyd medium to speed up the drying. If you already have some alkyd medium, test it and see.

If you do end up getting some CoZiCa or something like it, I would recommend using a solvent resistant dropper bottle to dispense it in predictable drop sizes and only add as much as is needed without going over the maximum recommended. Test always before using in a painting.

The red caps as shown in the photo, work better for me than the clear silicone caps. The clear ones break too easily, causing leakage in my plein air kit plus the ones I have do not seal well between the screw on cap and the bottle. I have to put some teflon tape on the threads to get a tight seal. I would not recommend getting that style. The black cap / red top cap design also has replaceable needles which is a better setup than the other style, but they will cost you more. Regardless of which you use, keep them in a water tight bag or container in case they do leak. If you can find them, get a set with a solid screw on cap as well as the needle tipped cap for a more secure seal when traveling.

I dispense CoZica using a toothpick, which is also used to blend into the paint.

A good dispensing method for studio work for sure. Perhaps not ideal for plein air work since you would need to keep track of the toothpick, the lid for the bottle and would have to constantly be opening and closing the bottle which gets annoying. With the lid off the factory bottle, if it gets dropped or tipped over, you are going to lose most if not all of the contents. The needle tipped bottles can be tipped over without much risk of spilling as long as you don't leave it laying down too long and it is not over filled. With thin liquids I like to fill the bottle to the point where the liquid doesn't reach the needle tip when laying flat so it won't leak out even if left flat with the cap off the needle. With higher viscosity liquids like Linseed Oil, it is not as much of a concern.
