How are you folks labeling your glass chemical bottles? I want something waterproof and preferably stain resistant. I suppose one could etch or grind markings onto the glass but I'm looking for something easier. I do have a Dremel tool, BTW.
Ordinary pressure-sensitive vinyl electrical tape, white, written using a black Sharpie.
Easily visible. Never smears. Never deteriorates. Stays attached even in hot water. Peels off clean. Cheap. Readily available. Offered in other non-white colors if desired.
Heh... it seems I'm trying to make this more complicated than it really is.
Long ago I used masking tape and an ink pen but the tape always eventually got stained and I had to remove them with a razor blade once they became difficult to read.
Write directly on the glass with a marker. When you want to clean it off, alcohol or acetone will do the trick. Of course this will not work with brown bottles, but it is rare that you need a brown bottle.
For glass bottles that are already labeled apply a thin coating of hot paraffin with a brush. Afterwards the paraffin and label are easily removed with a razor blade. This is what we always did in the lab. The coating is impervious to strong acids and bases. Blocks of paraffin are available from stores that sell canning supplies.
My writing is too sloppy so I like to print labels on paper from my computer and then affix them to the bottles with clear packing tape.
I can also make the printing any size I like, colors, or pictures.
I print paper labels, then use clear, 2" wide packing tape to cover. Labels are 1" . That leaves 1/2" top & bottom for overlap to seal the paper. Rarely do I have to replace the label. Use it on brown glass bottles and both brown & clear plastic bottles. Cheap and effective.
Once upon a time I had access to a manual laminating machine. That really sealed the paper labels . Still used packing tape to apply to the bottle.
