1kg - 35,27oz glow in the dark luminescent offers glass stones pebbles sky-blue

Sky-blue glowing glass stones 1kg - type KBL 20-30

Our glow in the dark stones are made from strontium aluminate base luminescent pigment mixed in glass. Thanks to that fact our stones have great resistance to environment - direct sunlight, UV, moisture, friction, high and low temperatures, even acids and alkalines. Glow in the dark stones are also neutral to environment. Because of such high durability this stones can be used as addition to concrete or used separately as gardening decoration, aquariums and flowerpots filling, general home decoration...

Unlike plastic or resin based stones our glass stones are way more durable - so if you need product that will have high resistance our stones is the best option.

Glow in the dark stones use photoluminescence effect - thanks to natural or atifical light it charges and then glows in the dark. Greatest effect is visible in first hour and with time glowing strenght decreasing but in deep darkness glowing is visible even after 12 hours. For best effect stones should be in sunny place during day (or near artifical light source). To fully charge stones needs 15-45 minutes depending on light source strenght. offers Glowing effect is good visible in darkness or sewmidarkness - bright street light near our garden can efface glowing effect.

Glow in the dark glass stones can survive even 500C temperature - but as glass product it doesn't like rapid temperature change ( over 150C change in short time). Because od such rapid temperature change glass stone may break. So stones should be used away from fire.

Stones may be slightly covered with abradant dust from production - so before first use we should wash it with water.

We also have in our offer sky-blue and aqua-blue stones.

We always try to give you the best option for shipping. Because of that default shipping firm is TNT - for Europe it took about 2-5 working days for delivery and for other locations about 10 working days (delivering time may extend due to customs clearance).

For other countries default shipping is via air post (shipped by Polish Post and delivered by your national post).
