The Brightest Glow In The Dark Stones on The Market

Glowing Pathway - Glow Stones - AGT

“Eco-Friendly, Electricity Free Photoluminescent Aggregates”

Ambient Glow Technology AGT™ is the market leader in high performance glow stones, glow pebbles, and glow rocks for concrete and asphalt. It all started in 2008 with the current industry standard, Commercial Grade Glow Stones and has since perfected the creation and application of high performing glow in the dark stones for almost any type of concrete and asphalt project. Whether you want to add a glowing ambiance in your pool or create an eco-friendly glowing path through a park, AGT™ has the products and the knowledge to make your project perfect.

Glow Stones  - What are they?

Glow stones also known as photo-luminescent aggregate were first introduced to the concrete industry in 2008 by Ambient Glow Technology – AGT™ and have since gained global notoriety due to their magical glowing qualities. Unlike shimmering, Mica-laden or fiber optic embedded concrete, glow in the dark stones ‘self-power’. They absorb UV spectrum light and store it until the charging source is no longer present and then begin to give off their energy in the form of ambient light. This maintenance-free, charging and discharging process will continue indefinitely allowing concrete and asphalt surfaces to luminesce for many years to come.

How Do Glow Stones Glow? Are There Different Types?

In general, glow stones are powered by photo-luminescent (glow) pigment otherwise know as Strontium Aluminate - a non-radioactive rare earth element. This glow pigment is mixed into either resin or glass to create a glow stone. Different grades of glow stones contain higher or lower loading rates of glow pigment. It’s also important to note that there are different qualities of glow pigment as well - the higher the quality, the brighter and longer the glow. Glow stone grades range from hobby-grade plastic pebbles and glass glow chips with a glow time of approximately 10-60 minutes, to high performance AGT™ Commercial Grade and Ultra Grade non-shrinking resin glow aggregates with glow times of over 10 hours.

What Makes One Glow Stone Perform Better Than Another?

The answer lies in the loading rate and material quality of glow pigment used. The lower the glow pigment quality and loading rate - the lower the overall glow also known as luminosity. Glass glow chips tend to exhibit a lower luminosity than for example a non-shrinking, resin–based glow stone. This is due to the fact that molten glass cannot bind with higher levels of glow pigment without affecting the molecular integrity of the glass itself.  As well, the high temperatures at which glow glass chips are produced effect the glow pigment’s ability to glow. On the other hand, AGT™ Commercial Grade and ULTRA Grade glow in the dark stones are made with a specialized non-shrinking resin which can absorb much higher loading rates of our proprietary super-luminosity glow pigment – allowing AGT™ glow stones the ability to out-perform all other forms of glow aggregates, natural glow marble or glow crystals commonly found on the internet.

How It Works

To ensure our customers receive the best glow stones on the market, the R&D division at AGT™ Glow Labs has spent an unnatural amount of time perfecting our formula to create a photo-luminescent aggregate that meets and exceeds all expectations when it comes to material quality, glow duration and price. In 2015 we made a breakthrough to which we unveiled the world’s first DIN67510 Part 1 Compliant super-luminosity glow stone - AGT Ultra™ Grade. This new formula has been third party tested and guaranteed to exhibit the highest luminosity and glow persistence technically possible.

AGT™ glow stones are:

  • Non-toxic
  • Will last for 20+ years
  • Will not shrink or change shape due to any weather conditions
  • Can be applied in any design
