Můžete mi vysvětlit, co u Vás znamená termín fluorescentní /flourerescenční? a co to má dělat? ... když pominu tu záměnu "Č" za "T" v anglikcé skomolenině. ... koupil jsem u Vás 4 fluorescenční vlákna, 3 od Gembird byla alespoň průsvitná a propouštěla světlo, toto od C-TECH je naprosto neprůhledné. Na světlo nereaguje ani jedno z nich. Nevím, školy nemám. Ale měl jsem za to, že fluorescence je forma luminescence a že po nasvícení by měla vlákna svítit. Většina luminescentních věcí je aktivní už po cca 30ti vteřinách světla, tady se nic neděle ani po hodině. Tak v čem jsou tahle vlákna tak výjimečná?
