Thanks Frank, definitely worth experimenting with these! I'll let you know if any of them work out well.

Have you considered using glass micro-beads?
An average salt grain is 0.3mm and you can get glass beads in similar sizes. https://www.amazon.com/Reflective-Standa......27PHNFJC
Think inside the box. . . it's less crowded.

Glass micro beads are remarkably similar to what was suggested to me by the late Lou Lancaster to 'spice up' a salt pour.
He managed to get some reflective glass beads to give sparkle to the salt. These reflective glass beads are usually used to mix in with white paint so that highway signs glow a bit when when your headlamps hit them. Perhaps a source for them can be located?

Don't know if these beads are being made any more, as way back in the era of home 8 mm and Super 8 mm film movies they were used on retractable movie projection screens. Most likely used in movie theater's screens as well.
Now with big screen televisions, no need for home projections screens. I believe they are part of the mechanism for the old P&L Drinking Glass Through Hat atop a candle stick holder. |

They have them plenty of places. I suggest getting them in the 500 micron range https://www.etsy.com/listing/616727163/f......elated-3

Yes! Glass road paint beads (solid not hollow spheres) are pretty close if the proper size is found.
The granular density of table salt is 2.2 grams per cubic centimeter and the bulk density, depending on finess of ground, is between 1.2 and 1.4. Glass spheres for road paint have a granular density of 2.0 to 2.6 and a bulk density of 1.2 to 1.8. The above mentioned silica (foundry sand, etc) has a granular density of 2.3 to 2.7 and a bulk density of 1.3 to 1.6. |

Individual salt grains vary from 0.03mm to 0.3mm. A slightly larger glass bead would be advisable to maintain the visual, so beads in the 500 micron (0.5mm) range should be ideal.

So, will need them to be about 2X larger to get weight right per grain. I find average size for table salt listed as between 100 to 300 microns depending on ground (similar to what you listed) so that comes to about 200 to 600 microns or so for the spheres. So it looks like you nailed it with 500 microns. Do you know when you buy such spheres how consistent they are? Will they vary like salt or will each be close to 500 microns? |

If it says "0.5mm" they'll be pretty consistent. Lots of the time they give a "mesh" which means "x or smaller" that's not very consistent.

Anyone had success with a good substitute for salt?

Yep. Been using the above spheres for Devin Knight's salt to bulb effect. Works perfectly and matches the Vernet Ethereal Salt.

Yes, the beads are still made. I have seen seen used in sand powered mechanism in old apparatus. I don't have a source but I imagine they are not cheap.

To Whom it may concern. I'm working with a vernet Salted in the U.S.A. Our brethen across the pond recommend Baking Soda. Now looking to find a U.S. brand with correct particle size. Any advice?

The best Bicarbonate of Soda substitute for salt is manufactured in Spain by Carmencita called "Carbonato Sodico".
For some reason, it is better than any US brand of Bicarbonate of Soda (Baking soda).ell. I have tried several brands here in the US and they don't work nearly as well. The one listed above is super fine, doesn't clump, and available in small 2 oz. bottles. I have been unable to import this to the US , unfortunately!
