Yes - Danish oil is a form of varnish.

As I mentioned earlier, it doesn't simply 'dry' it goes through a chemical change and 'cures' which in a warm room might take a few hours, or perhaps overnight. (You can tell by rubbing your finger on it. If it's cured, no oil will come off on your finger). There's no set formula for it - it differs from maker to maker, but it's typically a mixture of polymerised linseed oil, and tung oil (which is also from pressed seeds).

It's often used for kitchen utensils and wooden worktops as it's food safe.

You can read more about it here:

It's tended to be popular with radio restorers due to the finish obtained, and the ease of application. One of it's benefits is that most people aren't too keen on high gloss finishes, and Danish oil dries to a nice sheen. It's has been covered in many threads on the forum (including 'success stories') over the years, such as this one:

It's not expensive and is widely available from the likes of Screwfix.

Hope that helps.
