Sand under a microscope is much more interesting. Only 250x magnification is required...
@Torantino And they put cement in that and put it in a wall?
@Torantino It looks like a really fancy Bombay Mix.

@Torantino Crikey, that's amazing!

In my ignorance, I thought sand was virtually entirely made up of ground-up rock!

@LomanB @Torantino
Sand is defined as sedimentary particles in the size range 1/16 - 2mm (Wentworth Scale). There is no specification on what the grains are composed of & in my sand collection (yes really!) I have sands including those made of garnet (pink), olivene (green), magnetite (black), and many made from microfossils. Under a microscope they are all beautiful.

@geomannie @Torantino that definition makes a lot sense of sense. Beautiful.

@Torantino

That chicken-foot shape is really something.

You wouldn't think something that delicate could exist in the wild.

@Torantino
That makes me want a microscope...
@Torantino itโ€™s so cool!! It looks like pieces of candy

@johnettesnuggs @Torantino I thought that it was Yorkshire mixture (a sort of spicy cough mixture sweets).

Please use alt text to describe the picture.

@Torantino Iโ€™ve always wanted to do this! So beautiful.
@Torantino cool! Obviously marine sand, and I can spot at least five different phyla in there.
@Torantino ...and alla sudden you have a Dale Chihuly art installation
@Torantino Fascinating! I thought it was some chocolates at first.
