So after letting the costrel dry overnight (filled with lentils), the next morning it looked like this:
Not bad! I did some minor manual touch-ups with the beveling tool, but on the whole, a lot of the detail returned once the leather was dry and no longer so puffy.
Then it was time to remove the lentils, which was, ah -- easier said than done.
Lentils for days, my friends. Lentils that were now slightly soft and puffy from the water they’d absorbed.
When I thought I had gotten all the lentils out, I tossed some screws in there and shook it up and more came out:
And more. And more. Every time I did it, more lentils. At which point it occurred to me that I had been a fucking moron, because you know what is EXACTLY the same size and shape as lentils??
The fucking wax I’d been planning to use in the first place.
I did, of course, want to look up the Material Safety Data Sheet for the jeweler’s wax before I used it for a drinking vessel, and I found out--
--that eating plastic is bad for you.
lol, ALRIGHT THEN, I think we’re good.
...That said, in the end I decided to go with beeswax anyway, because the jeweler’s wax has a rather pronounced smell. It’s not a bad scent, but it is kind of... soapy/perfume-y, which probably wasn’t going to pair well with potable beverages.
So here is me melting down a lump of beeswax on the stovetop:
Everyone recommends a double boiler for wax, but you can also just... put it on low heat? o_O
Anyway, it took forever. I spent longer waxing it than I did on every other step combined, mostly because this is the part I was unfamiliar with. I was initially not using enough wax -- it wound up using that entire lump -- so next time I’m just going to dump in a ton from the start, way more than I need, slosh it around until it’s saturated and then pour off the extra. I was also very leery of overcooking the leather, because that is very easy to do, and it is permanent. I’d forgotten what the polymerization point is for leather (the point at which is begins to shrivel, a chemical rather than physical change -- around 200F?) but I knew I was having to push my oven close to that edge in order to get the wax to melt, so I was doing the whole thing in 5-10 minute intervals.
It was, needless to say, very slow. And then every time I went to fill it with water to see if was finished, there would be water leaking out from some holes, or darkening some patches (making it clear that the underside there that hadn’t gotten waxed properly), or ugh. After a day and half, I was like, SCREW IT, IF IT DOESN’T WORK THIS TIME, THEN IT CAN BE A *DECORATIVE* BOTTLE.
Luckily that’s when it finally held. Here is the waxing job, finished:
I did not dye the leather beforehand, because I wanted to show the color change that you get just from waxing/baking. It’s... a kind of meh shade of brown, like refried beans. S’okay, I’m gonna hit it with an antiquing paste.
