Will polymer clay baked onto a stone hold securely like this? Or maybe this is an airdry clay?

I've looked closely and see no evidence of glue. This necklace is about 8 years old and the stones are still very secure.

Is it possible that a clay can hold this well without a glue? If not, what glue is the strongest for a polymer clay and stone?

Thank you!!

Is it heavy like a rock is inside? Ive baked clay on a rock that i cut off and used the halves to make a vessel. Im sure it would have stayed on the rock very well had i left it alone. To answer your sure it would need glue. As to the best....not sure as my experience is limited. Ive used super glue with good results though.

Thanks Susan. Yes these are rocks so they're very heavy!

I would suggest an epoxy adhesive before a super glue.

reason being: epoxy will withstand impact (accidental dropping) better than super glues. Another reason is water resistance; super glues eventually succumb to moisture if prolonged exposure.

Hi SanneL, I think one would need a strong glue.

Pasting info below on my favorite glue. So far I have never found it to fail, except on cured Kato clay (which may need the surface roughed up a little and/or a brief alcohol wash with a cotton-tipped swab).

'Epoxy 220' two part clear (though slightly amber) epoxy that is mixed for a MINIMUM of one minute. It's a slow setting glue used in electronic and mechanical industries for superior bonding of non-porous components. Hardens in 8 hours (Hardens in 30 minutes underneath a heat lamp). Available from and Cannot be shipped outside of the USA. I have also seen it in some larger craft stores.

It is also available in the 'Epoxy 330' form which dries quicker, but I have read is doesn't form quite as strong a bond. I also had a reaction to E6000 several years ago and after reading the warnings on the label I started looking for an alternative. I've used it in making my jewelry for 3 years to glue metal to non-porous surfaces like cured polymer clay. I've never actually used it on stone or glass, but I assume it would work well.


Mixing directions

Epoxy must be mixed thoroughly. In many cases where an epoxy bond fails, it is because it is not mixed well enough. When you mix epoxy, it goes through several stages before it is ready to be used. It will first turn cloudy. Then it will get bubbles. Eventually (after at least a minute), it will clear up again. Make sure you mix until it reaches the clear stage before using.
