1. General Questions:
Q. How does Core Glow work?
Quick answer: All Core Glow products contain a photoluminescent compound that absorbs light energy in the form of photons. These are slowly re-emitted it at a lesser wavelength over a long period of time.
Full answer: All Core Glow products contain a photoluminescent crystalline compound, SrAl2O4, which absorbs light energy in the form of photons. The photons are slowly released over a long period of time which gives the Core Glow its constant glow. The light produces no heat of its own while undergoing this state change - not quite cold fusion but pretty neat nonetheless. The colour of the glow depends on the number of oxygen molecules in the compound. The presence of oxygen slightly alters the crystal field structure resulting in a change in the wavelength emitted when glowing:
Green SrAl2O4: 520nm
Aqua SrAl2O7: 480nm
Blue SrAl2O19: 420nm

Q. How long should I charge Core Glow stones?
Quick Answer: 1 minute for a quick burst, 1 hour for a full charge. Sunlight (broad spectrum) and UV lights work best, incandescent bulbs second, and LED, fluorescent, etc. third.
Full Answer: any exposure to light will excite the Core Glow compound, giving it a small charge, causing it to glow. The trick is to 'saturate' the Core Glow with as much light as it can take to ensure the long afterglow. This takes half an hour to an hour (just to be safe). UV lights work great for a quick burst of supercharged glow but this will not result in a full charge. Low light and shaded areas with ambient light will not result in a bright immediate glow but will charge the stones enough for a long afterglow.

Q. How long do the Core Glow stones last after a charge?
Quick answer: 8-12 hours
Full answer: Core Glow is always glowing, it just depends on whether your eyes can see it. During the day Core Glow is constantly absorbing light energy, especially if placed in direct sunlight or under a bright lightbulb. If you were to place it in a dark room you would see that it is glowing the whole time. Core Glow emits 5-7 candelas of light during its soft 'ambient glow' phase - compare to electric lights which emit hundreds. Initially, after a charge Core Glow will be so bright you can see it glowing even in a well-lit room, and it will cast light on the walls. After 45 min-1hr it will fade to a softer bright glow, and after 2 hours will settle into its ambient glow phase that will last all night. For this reason, it is best to view Core Glow in complete darkness- charge them up then give your eyes time to adjust. You will see them glow all night long.

Q. What is the lifespan of Core Glow stones?
Quick answer: 20+ years
Full answer: the photoluminescent compound in Core Glow is biologically and chemically inert. With proper maintenance, your glow rocks will glow indefinitely.
Q. Is Core Glow stones safe?
Quick Answer: Yes
Full Answer: Core Glow's photoluminescent compound, SrAl2O4 has been certified as safe by OSHA and ANSI standards. This means it has undergone rigorous product testing via international agencies before approval for commercial sale. It is biologically and chemically inert, does not contain high levels of dangerous elements or heavy metals, and has been embraced worldwide as an incredible improvement on the glow technology of the past - Zinc Copper Sulphide and its derivatives. Now, does this mean we will encourage you to eat it and treat it with disregard? No. The powder (when airborne) is a respiratory irritant and should be handled with respect using proper safety equipment (ask for our MSDS sheet). Also, keep the Core Glow away from babies and children who may be curious enough to try eating Core Glow. Safety first!
2. Project Related Questions:
Q. I am thinking of starting a glow project. What do I need to know?
Quick Answer: Everything you need to know is in our Core Glow Project Guide.
Long Answer: The best place to start is by reading through our Core Glow Project Guide. We have compiled our own experience into tips, charts, and troubleshooting help so your project will turn out just how you imagined. Have a question that isn't answered? Get in touch via our contact form.
Q. How much Core Glow will I need to make my driveway, patio, the stairway to heaven, etc. glow?
Quick Answer: You will need 1lb per 16 sq ft for 'high density dispersed coverage' - this results in the 'walking in a galaxy' effect.
Full Answer: Visit our 'Coverage' page for a more in-depth answer to this question or if you want to install over an existing landscape. Generally, we recommend 1lb per 16 sq ft for that 'walking in a galaxy' effect. In other words, this is how much you will need for 'high density dispersed coverage'. Tweak the measurements up or down to match your coverage preferences and budget restraints. If you want full coverage Core Glow Commercial Grade Marble covers 0.5 sq ft/lb.
Q. How do I make a glowing driveway and/or pathway like the one in your photos?
Quick Answer: Make your own glow path or driveway with our easy handy packs including gravel stabilizing the grid, pre-attached geotextile sheets, and info on how much Core Glow to add. It's that easy.
Full Answer: Use Core Handypacks to easily install your own glowing, stable, and permeable pathways, patios, and driveways. Simply level the area you want to be covered, lay down the grid, fill will gravel, and top with Core Glow. For an in-depth look at the grid system visit www.coregravel.ca. For projects over 500 sq ft get in touch via Core Gravel's contact form, our Core Glow contact form, or call into 1 855 777 CORE (2673).
Q. Does the area need to be in full direct sunlight for Core Glow to charge?
Quick Answer: No, but it will work best if it does.
Full Answer: Direct sunlight will fully charge Core Glow and result in a bright initial charge. In an area that gets partial sun, the Core Glow will receive a charge, but it may begin its 'ambient glow cycle' by the time night falls and may not hold the charge through the night. Also, note that light pollution in your area will render the glow invisible. Core Glow is best viewed in complete darkness away from electric street lamps, solar lights, and other electric light sources. Core Glow is best viewed under the moon and stars alone, ahhh. For more tips on how to optimize your Core Glow project read through our project guide.
Q. Can I use my indoor lights to charge Core Glow for my indoor project?
Quick Answer: Absolutely.
Full Answer: Indoor lights work very well to charge Core Glow, and gives you control over how much light they will receive. The best charge comes from a light pointed directly at Core Glow. You can use a UV light to supercharge an area to impress your guests and freak out your cat. For a comprehensive list of best lighting conditions take a look at our Project Guide, pages 1 and 2.
Q. Will sanding, shaping, or cutting Core Glow affect its ability to glow?
Quick Answer: Not one bit.
Full Answer: All of our Core Glow products are fully saturated with the photoluminescent compound rather than just being top coated. This means you can shape, sand, cut, smash, fracture, do whatever you want to Core Glow and it will still glow just as brightly as when it made its way to you. You may even notice it begin to glow as you sand or cut the Core Glow as the compound is also friction reactive!

Q. How is Core Glow Quantum different from Commercial Grade Marble and from CORE glow stones?
Quick Answer: Core Glow Quantum Grade Marble has the brightest and longest glow of all of the Core Glow products. Quantum glow has 2x as much SrAl2O4 by volume than our Commercial Grade and 5x as much by volume than CORE glow stones.
Full Answer: CORE glow marble is a cold manufactured process vs the high heat production for our Core Glow Stones. High heat limits the concentration of glow that can be achieved. This cold treatment method is tricky, time-consuming, and worth it for the brightest and longest-lasting Glow available. Not to mention the strength, quality, and natural look of the Core Glow Quantum and Commercial Grade Marble stone is simply the best.
Q. Do you offer Core Glow Samples?
Quick Answer: Yes - you can purchase a regular or commercial sample pack from our 'Shop' page
Full Answer: Core Glow samples cover all of our Core Glow products except Core Glow Powder. A great way to test out our products before choosing which type and colour to purchase for your project.
