Linseed Oil is great to use in small amounts when you need to rub some of the excess ink away from your wax painting, if you need to purchase linseed oil or any other encaustic materials please visit my online shop, I also sell a range of R&F products including pigments, wax medium in pellet form and bars as well as a small range of tools and equipment, I am gradually building up my supplies under Encaustic Wax Supplies UK.  Feel free to contact me anytime if you would like further information about working with wax or my Encaustic Wax Workshops, I offer one-to-one and also small groups, ideal for beginners who are curious about encaustic painting & want to learn the process.
