Could I use in fireplaces?

No, it's not recommended for use in fireplaces.

Can you add it to existing driveway or does it have to be mixed in when the concrete is poured?

It's recommended to add the CORE Glow Natural Stone in a concrete application when the concrete is still wet so it can bond with the concrete. You can add it afterward and seal it with a resin but it's recommended to discuss that option with a professional installer first as it can be a tricky install.

Can these be used with outdoor temps that are minus 5 to minus 10 below?

Cold does not affect our CORE Glow marble. They have been installed in areas that get VERY cold (-40+ c) with no adverse effects.

Can it be used in 122 degrees Fahrenheit weather?

The CORE glow marble can be used at these temperatures.

Environmental impact? Do they degrade at all? Toxicity in animals?

The CORE Glow Marble is nontoxic and chemically inert. Please feel free to view the MSDS sheet for this product found here.

How many stone would I need to purchase for a long driveway?

If you go with the medium density coverage, then you will be able to cover ~32 sq.ft /1 lb and if you choose High-density coverage then you will be able to cover ~16 sq.ft / 1 lb.
You can check out a complete coverage guide here:

Can the rocks be used in outdoor fire pits like lava rocks?

We do not recommend using this product in fire pits.

Can you put these in waterfalls?

They are very small and could get "lost" easy, but other than that, no reason not to.

Can these be used in water fountains?

Yes, they can be used in water fountains, provided there are no fish in the fountains.

Can they be driven on (by cars) over and over again if used on a shell driveway?

They most certainly can!

Can you mix in plaster for the bottom of a pool?

Yes, the CORE Glow can be added to plaster for the pool surrounds. However, unless you have a light source at the bottom of the pool, it might be too deep for the sun to charge the glow product.

Can you put them in dirt?

These stones are very small (1/2 inch at most)as such, we do not recommend placing them in the dirt as they will disappear very quickly.

Do they 'project' any light, like uplighting a plant in a pot? Or do they need to be visible to be seen?

They do need to be visible to be seen. It's recommended to spread them on the top layer only.

If I'm putting them in the top of the stones in a shallow multi-tiered waterfall, how far from the surface, but still under water, do they need to be to still get a charge from the sun?

As long as the sun (or light source) can reach the stones they will glow. Try not to go go deeper than 1.5 ft.
