These lampwork beads have cream coloured spots around the core which give off a phosphorescent glow when it is dark. They need to ‘charge’ from a light source first – both natural sunlight or LED torch light work well. They only glow brightly for a few seconds, but then can hold a faint glow for up to 10 minutes.
I think these are fantastic, but please note these are not a high grade bead – they are more of a novelty bead. They can vary in size and shape and be a little uneven around the holes.
