Coaster project | White cement vs Plaster of Paris | Which one is better?

Hi everyone. Today I'm going to compare between white cement and plaster of paris for my coaster project. Can i replace white cement with plaster of paris? Please watch the video. [UPDATE] - I have tried several test on this plaster and it break even if the correct ratio. I tried to mix with cement and it ain't worked either. At the end I found out that the quality of this plaster is superb low quality (from the review). I have changed to another brand and it worked fine now.
