Update: I found out after some experimenting that this stuff is also great for waterproofing veg-tan leather. I finished this Nexus 5 case with it.
In my post on making tablet stands I used hard wax from Clou. The stuff is not very expensive, but not cheap either: 9 euros or so in a German DIY store. Since the tin stated it only contained linseed oil, beeswax and carnauba wax, I thought I’d have a go at making it myself. I’ve been making cosmetics for a while (very manly stuff, lip balm and such), and I reckoned this stuff is not that dissimilar. Here’s how I did it:
15g beeswax (1/2 ounce)
15g carnaubawax (1/2 ounce)
60ml boiled linseed oil (2 US fluid ounces)
30ml vegetable oil (I use wheat bran oil, because it’s colourless and in my experience, it doesn’t spoil) (1 US fluid ounce)
6 drops of essential orange oil (optional, to make it smell better. You will be putting this on your furniture, after all) (6 US drops)
And, very important: something to put the stuff in. I used a “herrenschokolade” tin. It’s a German brand of dark chocolate that you can buy in a tin. It’s exactly the same size as a wax tin. Nice.
Put all ingredients except for the essential oil in your most retro double boiler. Let it melt. The carnauba wax has the highest melting point so it will take a while to fully dissolve. I don’t know if any of this stuff is flammable but I would be careful with a gas stove. I use induction so no problem for me.
…pour it into a tin.
The end result looks almost exactly the same as the “hartwachs”. It smells nicer, though. Also a lot cheaper. This is the “Bill of Materials”:
15g beeswax (at 9,50 per 500g)= 0.28
15g carnauba wax (at 9,95 per 500g)= 0,30
60ml boiled linseed oil (at 12 per 500ml)= 1,44
30ml vegetable oil (at 1,20 per 1.5l)= 0,11
6 drops of essential orange oil= practically free
This recipe yielded two tins by the way, so that’s a little more than one euro (1.2958 U.S. dollars at time of writing).
