I was thinking of using the label on the vial for very short instructions. I haven't thought it all thge way trhrough yet, but here's what I initially thought of doing.<br><br>A wrap around paper label with four horizontal segments. One for the content name, potassium permagnate (and perhaps "do not eat." ), and the remaining three for the carius tints and uses for disinfectant and water treatment. I'd like to add color strips for each of the three uses, just like test strips for chlorine and other chemicals. Does any one know where I can find examples of the three various shades. Or can someone give me the RGB equivalents?<br><br>Then perhaps the label and be sealed around the vial, which I bought through Blueline Outfitters, via clear shrink tubing. The tubing would hold the label in place as well as form a seal around the lid.<br><br>Comments?
