A wierd question I know

[randycab]

puzzled: Hi there. I have an unusual question I think. I need to adhere some oyster shell clusters to glass cylander vases for lighting for an oyster roast. I can hot glue them but I am afraid that the fire of the candle inside the cylander will heat up the glass and the glue will melt and the oyster shells (which have some weight) will drop off. Does anyone have a recommendation for something that will fairly quickly attach the oystershells and stick to glass but not be meltable. Thank you so much.

this stuff is the bomb although i would think that you might need a smooth enough spot on the shell to make a big enough area to glue.

Epoxy. Avoid using large amounts, as the shrinking of the epoxy as it cures can crack the glass.

I agree with brian... Epoxy has been pretty good to me.

Epoxy, E6000, JB weld, Super glue (gap filling formula)....

If the lamp shade is tapered you could also use wire rings and wire the shells on....

i like doug's idea for wiring them on...even if they are straight cylindars, i think you could twist the wire around & it would look good.

if the epoxy will lose it's seal around 400 degrees? is that right? how hot will the glass get over a couple of hours i wonder?

i thinkwiring would be faster, easier, & less to worry about. you wouldn't have to hold them in place while they set.

I'm really not into wiring them. It feels like it would be no fun and not the look I want either. I could try the epoxy idea. Does epoxy adhere right away and then take a while to completely set. It might be a pain to sit and hold the shells if it takes a whie.
Thanks for your input.

Goop has worked for me, but I don't know what its temp range is. I'd suggest trying it out with some samples before the big deal.

the devcon epoxy sets in under 5 minutes.

JB weld holds up to engine temperatures.

Use Epoxy that dries in an hour or more because it won't break as easily as the faster setting stuff - my own experience with epoxies...lol.

If it's only gotta last that one day, maybe use clear silicon caulk? It's cheap and easy to apply. Test it first though.
