No offense, but do it the other way around:
Get some silicone chaulk from your hardware store.
Put a good amount of it onto your glass use some old spatula, wooden stick or whatever to scrape it flat.
Whatever uneven spots are left you fix using your fingers dipped in a bit of soapy water.
Let cure for about a week in a ventilated area.

How about RTV silicone?


Edit: Maybe I should be linking to "Silicone rubber" instead:

It is also called "silicone seal," or "silicone sealant," and it is commonly found in hardware stores. Certainly silicone will stick to silicone, and I am pretty sure it will stick to glass too. In fact, I think that is the traditional way aquarium tanks are manufactured; i.e. with flat rectangular panes of glass, glued to each other with silicone seal.

As for chemicals that will "seep thru" glass? Are you serious? The reason chemistry students, and professional chemists, use glass for their glassware, is because glass is inert and impervious to most chemicals.


Also, RTV silicone is not particularly toxic. I would be completely unworried about cured silicone, on the other side of a few millimeters of solid glass.

Have you ever tried to make silicone stick to silicone?
Let me know please how you managed to get the stuff to bond if one silicone part is already fully cured.
I only know a single method and can't recommend it due to the toxicity of the chemicals required.

Silicone basically sticks to nothing really well... Best i had was with silicone-chaulk (The silicone you use in the bathroom to seal edges) and use this a sort of glue...
Remember that often, this type of silicopne is very slow in setting.
But with your intended use thats no problem: Just add a ring or dab of the silicone on the glass, set it on the coaster and let it set for 24-36h.

If you want, you can use transparent (ish) silicone for less obvious glue-spots..
