Slightly off topic, but if you ever write on a whiteboard with a sharpie, you can write over the text with an erasable marker and then wipe it away.

This works because the solvent base for the ink is alcohol, so a much simpler method that doesn't waste ink is to use a small spray bottle of isopropyl alcohol. Ideally 99/100%, if you can get it. (Try eBay.)

This doubles up as an effective whiteboard cleaner.

Get a real blackboard made of slate and quality chalk. Much higher resolution than markers.

I'm glad they work for you, but out of curiosity, does anyone else find... just about everything about blackboards unappealing? The feel of chalk scratching on the board, the sound, drawing the characters (making curves feels awkward to me), even the chalk dust. I prefer whiteboards in almost every way except for markers drying out. It's one of those things I've kinda never understood why so many people prefer chalkb…

Scratchy chalk is low-quality chalk or poor technique. Every writing instrument has its own techniques. Like how fountain pens work better at a lower angle and lower pressure, and ball-point pens work better at a higher pressure and the angle doesn’t matter so much.

Earlier quoted context omitted.

Isopropyl removes all inks and glues. It's incredible. It's also fantastic to wash your hands with when doing cell and tissue cultures and trying to avoid contamination.

It's also similarly great for killing braincells when auto-applied orally

No. You're thinking of ethyl alcohol. If you ingest isopropyl alcohol you're gonna have a bad day.

Oh and make sure the label on the ethyl alcohol does not contain the word "DENATURED." That's code for "tastes like shit and makes you sick."

Or poor quality boards. I know I didn’t use a real slate board until later in university and it makes a world of difference. Really you need both, great chalk and a great board. But when you have both the feel is superb :)

Well, if the stated goal was to kill brain cells, I'm sure either will get you there

I bought this 4'x3' Black Glass Board back in 2017 for $150! I write with white and neon colored liquid chalk markers and it's the best! Here: https://a.co/d/hlrwPHQ Enjoy it.

Is there a particular advantage to getting the black version of this versus the ultra white version?
