I'm not sure how pure white you refer to but i think all of them will give me a white result. In this video, plaster turn out to be more white due to the colour i mix them with. Pink gave warmer colour which blue gave cool tone.
Gypsum is generally safe to use. However, it is important to handle gypsum powder with care and to follow appropriate safety guidelines when using it. Inhaling large amounts of gypsum powder dust can irritate the lungs and cause respiratory problems. Therefore, it is recommended to wear a mask and protective gloves when handling and using gypsum powder.
