A little bit of wisdom I'd like to impart to you all, regarding the tricky business of transferring a label from a plastic vessel to a glass one. Apologies if this has been stated before.
I've tried the blow-dryer method, and that does work, but it is time consuming and still tricky to get right. Here's my alternative method:
Clean glass vessel outside well, removing oil, dirt, etc. Transfer A/S to glass vessel so the original plastic container is empty.
Boil some water.
Pour boiling water inside plastic container, maybe 3/4 the way full. It may start to distort, but that's OK. The key is to heat the label glue, which should start to peel, and subsequently become very easy to unstick from the plastic container.
Peel off label smoothly, and then quickly transfer it to your clean glass vessel. Sometimes the edges may furl up, but just keep them firmly pressed down onto the glass, and eventually the label should stick.
Voila! Your label is now transferred with most of the glue with it!
