Summary
| Description |
English: Thermoluminescence of fluorite (chlorophane) specimens which emit light when heated on a hot plate. Too high a temperature can break the crystal. The phenomenon only lasts for a few minutes, then disappears. The light emitted at the beginning seems to be white, and tends to be a little blue at the end.
Afrikaans: Termoluminessensie van fluorietmonsters (chlorofaan) wat lig uitstraal as dit op 'n warm plaat verhit word. 'n Te hoë temperatuur kan die kristal breek. Die verskynsel duur slegs enkele minute voor dit verdwyn. Die lig wat aanvanklik uitgestraal word, lyk wit en is geneig om aan die einde effens blou te word. |
