Had this laying around - a lump of beeswax I got from my grandpa with lots of impurities.
Wanted a finish I could use on food contacting surfaces (I'm planning to make some cutting boards soon).
As I've read on various sources all over the internet the right proportion should be 1 part of beeswax to 4 parts of olive oil.
So you should weigh or in some other way (not sure what?) measure your supplies and go for it.
As you can see here - 30g of beeswax with 120g of
olive oil mineral oil should get me somewhere around 150g of polish.
If you're using wax without impurities you may want to grate it.
I used extra virgin olive oil. Any oil would do I guess. The smell with olive oil isn't too nice afterwards, so make your choices. I'd recommend to use something you can get locally, since it's most likely the most fresh and natural.
Update: Just use food safe mineral oil unless you absolutely have to make this right now right there and have no other options. The ratio is the same, it's tested, works and doesn't go rancid.
