Bonjour a tous

Une observation de cette nuit

Il s'agit de sel de table que j'ai dissout dans de l'eau tiède et après j'ai mis une goutte sur une lamelle que j'ai mis au dessus d'une plaque chauffante pour l'évaporé et voici le résultat

Objectif employé Achro origine 10

Pour la première photo staking de 24 vue est combiné avec CZM

Et pour les deux autre filtre polarisant es éclairage oblique .

Researcher Bino et MicroCam 3,0 MP

Hi Vasselle,

Very nice piramides.

Crystals are so interesting, both visually as in your excellent photo and also mathematically, as they demonstrate a lot about symmetry in nature.

Let there be (oblique) light.

Hello Seb,

Very nice salt crystal images. Because NaCl is not birefringent, under the polarizing microscope you may want to try other chemicals that are birefringent., such as ascrobic acid, citric acid, magnesium sulfate (epsom salt), etc. You may also get some ideas by clicking on "Gallery" at the top of the screen.
