What makes for a good blackboard? Could they be reproduced?
- nwhitehead 11y agoThe old good ones are heavy, dark, and silky smooth. The new ones are lighter, noisier, have more friction, and erasing leaves more of a mess (in my opinion). Reading online people say that the old slate ones were harder to erase and had glare problems. I agree with the glare, the old style boards do show glare from sunlight coming in from side windows which is annoying.
