    Default Adhesive

    A very basic piece of advice please. The best adhesive to glue an amber cabochon of 8mm into an 8mm bezel set ear stud and any general words of wisdom.

    There is no need to glue cabochons. They are he easiest of all shapes to set if you make your own cup.
    Bought cups of course do not fit most stones of the same nominal size unless the stones are man made.
    Just watch some videos on the subject, or buy a simple book for beginners, such as Anastasia Young.

    Amber being rubbery will not glue well, because glues tend to be rigid. If you are desperate to finish, try gel superglue. Dennis.

    I would suggest that you try Araldite Instant which sets quickly and is a clear glue, see; https://www.amazon.co.uk/Araldite-In.../dp/B006JYQ1I6 I have used this glue many times when required without any trouble, when set it is colourless and does not effect the colours of semi transparent stones.

    Ah, just the info I was looking for.
    My design doesnt involve completely flat surfaces so if it’s going to work it needs a good adhesive. Do you think it would be secure enough for something like this?

    The sea glass doesn’t have a highly polished surface but the silver will obviously be smoother. Would I perhaps need to slightly roughen the surface on the metal at the point of attachment?

    It's not completely clear why you want to glue your sea glass Hazel, perhaps a picture of it would help.

    In principal glues work better on roughened surfaces, because that increases the surface area. Both gel superglue and clear epoxi, such as Araldite help to fill small gaps where the fit is uneven.
    That said, mechanical retention is more certain to work in the long term and less likely to yellow the colour as it ages. Dennis.

    It's a common misapprehension that glue should be applied to roughened surfaces because it increases surface area. In fact the opposite is true. Glues work by making permanent a vacuum between the two surfaces. The thinner the adhesive layer the better the adhesion. You don't rough up a solder joint, do you? Solder will only flow across a close, smooth and tight joint.
