I have a piece of transparent plastic with UV LEDs on the edges, about 1m (3 feet) diagonal, 5mm (0.2 inch) thick.
I guess it was a DYI transparent board meant for shooting video lessons, the type that can be written with color markers that fluoresce while the UV LEDs on the board's edges are on. No idea what type of transparent plastic it is made of, could be "Plexiglass" or could be "Lexan", IDK how to test.
I want to suspend it against a white wall, to improvise a small whiteboard to scribble on. Already have various markers, permanent and highlighting color pens, none of them are dry erase pens.
The idea is to use what I already have, but without permanently taint or scratch the transparent board. It's for the lab at home, so no intense or public use.
I really don't want to damage that transparent sheet, because in case it's not suitable as a whiteboard, then that plastic sheet will be ideal for making some transparent boxes.
- How can I test which pens are safe to draw/erase?
- Is it safe to assume that those pencils working on the plastic of a PET bottle will work on the plastic of the transparent board, too?
- Would a dish-washer sponge leave scratches if used as eraser? Any personal experiences/advices with transparent boards?
