I think you mean "methanol" ? Chemically, it would be a bit of a
stretch to say that "silicones are [methanol] based", but it would
take a few hours to explain properly!

There are a variety of different types of silicone, and they interact
with solvents in different ways. I would not be surprised if methanol
absorbed into the silicone and caused it to separate from the glass.
Acetone would probably do that too (acetone is the recommended cleanup
for silicone bath caulking).

Yes, methanol is fully miscible with water.
