Science - Science (general) / high school science experiments
French term or phrase: caustiques (this specific context)
"ils allaient exploiter des phénomènes lumineux, les condensations animées de crayons réfléchis sur du clinquant (ce que l’on nomme des “caustiques” en classe de seconde), l’agitation des poussières sur un trembleur électrique ou encore les tracés de la limaille aimantée."

This is a description of visual effects in the early days of French Television, visual experimentation similar to the sound experimentation of musique concrète. This seems to be connected to high school science experiments, and I think that is the most promising direction. I must have missed that day, because it doesn't add up to me. I have no indication that this was ever actually used on television.

This concerns the Groupe de Recherche Image (GRI) of the RTF circa 1960.
