Finshes
A "Finish" is applied to wood to protect it. There are many types of wood finish - some more natural, which bring out the best of the wood, some which are rather synthetic. Some easy to apply, others not so.
In the past 14+ years, I've used a number of finishes, which offer a variety of features, and now use Danish Oil, Finishing Oil and Microcrystalline Wax. I also hope to restart using lacquers again soon.
None are an easy to get great results, but I hope my many years experience provides a good quality finish - my secret is not to rush it, and apply light layers, with plenty of practice to know what is just the right amount.
As someone with rare allergies, should you, or someone you know, use items that come into contact with any of these items, it might be worth letting them know which finish is used.
