Tad Spurgeon has spent decades researching and testing traditional oil painting methods, techniques & materials from the past 500 years and he has compiled all that knowledge in this helpful book:
LIVING CRAFT: A Painter's Process, 14th Edition, by Tad Spurgeon

However, while it has been a long personal labor of love for Tad, he is no longer publishing a hard copy of his book and instead, has converted it into a pdf you can now download for free. All 566 pages. Which makes it an incredible gift from Tad to you. (Plus, as a pdf, you can easily search the entire book in a way you can't with a printed copy.)
So if you are a technique & material geek like me, I recommend you download this eBook and refer to it whenever you have a question about historical painting methods, or want to experiment with old-school methods used by the Old Masters. I've referred to Living Craft for years now because it is an invaluable resource for arcane, yet fascinating historical methods seldom found anywhere else.
This eBook is posted here with Tad's permission.
In my opinion, all oil painters owe Tad a huge debt of gratitude for the time and effort he invested in producing this volume; and now we owe him even more because he is now offering it free to anyone who wishes to read it.
Thank you Tad for your curiosity & commitment to the craft of painting.
