Slow Dry Medium

bmw

Hi Everyone, 
 I mixed a jar of slow dry medium quite a while ago.  How do I know if it is still good to use?
Thanks

It doesn't seem to go bad.  I mixed up quite a large quantity and still just fine.

If the jar had an airtight closure the SDM will be good. Open to the air SDM will gradually lose the volatile clove oil and the linseed or walnut oil will oxidise.

Thanks for the info.  The SDM is stored in an air tight jar.  I appreciate the knowledge and sharing that is on this forum.

I mixed some paint with the SDM and put it in 8oz mason jars about 6 years ago, recently used it, it’s still good, as is the extra SDM I mixed.
