I've used plenty of paste wax in my woodworking adventures and never worried about the ingredients until I started making utilitarian items. My finishes for bowls, cutting boards, or any other item to be used with food are solvent free and 100% natural. I thought I'd share a recipe for non-toxic paste wax. The best part is it's super easy and you get to melt stuff!
Step 1: Materials & Directions
So here's the catch, you married men should first request clearance to the kitchen. We'll be melting wax in a double boiler on her stove top. Godspeed.
Assuming you have permission to use the kitchen (I don't want any messages from angry wives, they scare me) you will need a few items.
- A pot to boil water in (can be one of her pots as long as you have permission)
- A metal container in which to blend your melted wax and oil (I used the same container for storage)
- A heavy duty grater (seriously, don't use the cheese grater you got as a wedding present)
- Bee's Wax
- Carnuba Wax
- Tung Oil / Walnut Oil
- 1/3 cup measuring cup
- The most important item! Pliers or vise grips to remove the mixture with.
- Something to stir with. Non melty is a plus!
The least fun part of this project is grating the wax. Especially if you have a wimpy grater. Had I considered how hard wax is compared to cheese, I would have coughed up the extra cash and bought a good grater. Oh well. The recipe I used is pretty simple.
- 1/3 cup Bee's Wax
- 1/3 cup Carnuba Wax
- 1 cup Walnut or Tung Oil
This makes a wax that is easy to apply and buff out. Changing the ratio of Bee's wax to Carnuba wax will change characteristics of your finish. Carnuba wax is very hard and brings out great luster in a piece. Bee's wax can also give a nice shine, but will dull more quickly than Carnuba wax.
So why use Bee's wax at all? Well, it's much cheaper and is more malleable. If you had a paste wax that was just made up of Carnuba wax and oil, it would be a crumbly mess. Aside from that, I don't want my cutting board to shine like a new Lamborghini after treating it with paste wax. This is the main reason for using a blend instead of just one wax. By altering the recipe, you can control the sheen and durability of a paste wax finish. Enough of the wordy stuff, let get on with it already.
Step 2: Melting
Before you start melting wax, add enough water to the pot so that the water level is about 1/2" below the top of your melting container.
Add the wax and oil to your container and turn up the heat. You can go ahead and crank it up, but be sure to turn the heat down before the water starts to boil. You don't really want water in your paste wax, so try to avoid it. A little won't cause any major trouble, but just be mindful that the less water in your paste wax, the better.
Once everything is melted, you can take the container out of the pot of water with pliers. The stuff is kinda hot... Spilling is not recommended.
Step 3: Cool Down
As the wax cools, keep stirring the mixture so that the oil does not separate. Putting the container on a cooling rack helps to speed up the cool down process. I've also put the container in the fridge for about a minute at a time when the mixture is fresh out of the hot water.
Once the wax is cooled, it's ready to use. Be sure to write down your recipe so that you can repeat it once you run out, or so you have a starting place for changing up your paste wax recipe in the future.
This is a basic recipe and you can certainly add colorants or metallic flakes to the wax for a different effect. However, depending on what you add, your finish may no longer be food safe.
