That’s a neat find. Those 1950‑s radios were all about vacuum tubes, so they had a lot of hidden capacitors that can hold a charge even after you unplug them—better be sure they’re dead before you touch it. They also used large metal dials and a lot of brass, so the radio itself is a small snapshot of the era’s craftsmanship. Just keep an eye on any loose wiring or exposed metal that could short, and you’ll be good to go with your quirky planter.

Just be sure the dial’s metal is clean—wipe it down with a bit of vinegar to remove any oxidation, then dry it thoroughly. If you’re using it as a rim, you can sand the edges gently so there’re no sharp points that could cut the potting mix. Once it’s smooth, you might seal it with a clear, waterproof varnish; that’ll keep any water from seeping into the brass and help it last. A small, round dish under the rim will hold the soil, and you can line it with a silicone mat to catch any leaks. Then you’re all set for a tidy little terrarium.
