Plaster of Paris is a popular substance that is utilized most commonly for sculpting materials and in gauze bandages. While we have seen many applications of this material in our everyday lives if we try to understand its chemistry, plaster of Paris is a white powdery chemical compound which is hydrated calcium sulfate that is usually obtained from calcining gypsum.
Plaster of Paris starts to degrade around 1000 degF below good forging temps. It is also not an insulating refractory and so it drives up fuel costs. Videos advocating it's use are indications that any idiot can post a video.
