Anybody have any tricks to keep agar from sticking to glass?

I shook these Sunday night. They are definitely recovering, but they're not as pretty white as they were. These are agar to grain transfers. I had trouble with the agar sticking to the jar. Still worked out I guess. Anybody have any tricks to keep it from sticking to glass? 🧞GT🍄GARGAMEL comment: Whatcha got under that foil? If you have any sort of filter on your lids, lose the foil wrapper. Remember, your mycelium needs to be able to breathe. It is a living thing. I shake it once or twice while colonizing and one last time after it’s 100% colonized. Some contaminants are sneaky and like to hide until it is spawned to bulk, so one last shake gives your grains another opportunity to expose any tams. This is just how I do it, and you are free to utilize the advice or not As far as agar sticking to the glass, there isn’t a great way to prevent it, and if the mycelium transfers to the grain anyhow🤷‍♂️ no biggie.
