After knocking out a Jacaranda bowl in one lunch break, I was a little fired up that night to do more, so I got a stick of Jacaranda from the pile and cut it into some small pieces for making tiny champagne glasses.
My attempt here was to go very thin-wall. I didn’t bother with process pics (it gets a little tedious sometimes :) You can see light shining through the walls into the interior of the glass:
Unfortunately, I went a little too thin in the middle. Note how much extra light is coming in around the widest part of the bowl:
Also note in the previous images how wet the outer edges of the wood are down at the base. The whole thing was like that, but centrifugal force is pushing the water in the tree to the outsides, and sprinkling me with it as I turn.
The shape of the glass came out very nicely. I turned the outside of the glass bowl first, then the inside, then went back for the stem. Still, I didn’t feel completely secure when doing the inside. I used my internal scraping tool mostly, as the other tools in my collection don’t handle deep, narrow passages like this without so much chattering it would seem they’ll shatter the piece. I’ve seen a few tools that will work better, but I especially just need smaller tools. Much of what I have at the moment is geared for larger work.
My thumb fits nicely :)
I gave up on this one, as the thin middle was so thin, it was sort of cracking. Fibers were sticking through in both directions, and while it was still wet, I could push on the rim and make the top half of the bowl move away from the bottom half, before it would spring back. Now that it’s dry, it won’t do that, but it feels absolutely paper-like and fragile. It would be really hard to finish well. I tried, though.
I rubbed on a mixture of denatured alcohol and brown aniline dye. It came out looking dark brown. Nothing special. Later, I wiped on some water-based wipe-on poly, and it looked ‘better,’ but it’s still just not worth anything. I parted it off into a proper glass, and it must weigh less than a mailed letter. I feel a stiff breeze could blow it skyward.
I’ll probably make some more of these, and just go more carefully and leave things thicker. There’s something neat about a wood glass that’s feathery light, as long as it’s just thick enough to be sturdy.
