Super Glue

Hunting for crystals, I tried a drop of Super Glue on a slide and let it dry for an hour.
Didn't get birefringence , but got a look at this interesting interlocking structure. Note how the edge reaches out to grab the slide.

Astonishing 'behaviour'...

Thanks for sharing that image.

Had to add one more, this is the super glue bonding the coverslip to the slide.

I would not recommend getting un-cured superglue anywhere near optics, especially objectives, as it gives off fumes as it cures and these can fog lens coatings.

Not likely with my phase contrast objectives!
No, these are place the substance on the slide and set it aside for the rest of the day.

Very interesting, thanks for the photo`s. I would keep any super glue formulas away from microscope optics, because I have seen what cyanoacrylate formulas can do with some optical glass I was working with,,, as stated above, esp. if you have heat in that area even after the glue has set.
What I understand is that you will find no singular measurement of toxicity for all cyanoacrylates adhesives because of the companies that make the product and the formulations used. No doubt this product and others like it can fog up and ruin optical glass.

Yes, your method works well...

Hi Radazz,
you found an interesting and attractive microscopy object here! There are comparatively few man made microscope objects so this is a welcomed addition.
I saved the topic for later use.
Drying adherives could also offer interesting views.
With epoxy I had different results: Some were perfectly clear, some had a structure in the cured glue.
UC curing glue for artificial finger nails allows to make perfecly clear lenses that offer a quite acceptable view. Just put a drop below a slide an let it cure.
