Have you inherited a studio’s worth of raw materials but have no idea what they are? On today’s episode of For Flux Sake the gang talk about how to test mystery materials to find out their usefulness. They also talk about the best ways to record the information you learn from your test tiles, and Matt and Rose give a report on their trip to the Fiesta Ware factory.
