  • When is a bag of plaster too old to use? When it dries I get little sandy bits when I carve it.

  • When a bag of plaster is opened it starts to absorb moisture from the air and slowly goes off!

    After a few months it is usually no good..The plaster in this video is fine strong plaster for sculpture, not the stuff you do walls with!

  • Search Plaster of Paris

  • Any kind of clay will do, It is simply an impression in the clay filled with standard casting plaster. Clay and plaster will always separate easily but impression molds can be made with many other materials such as sand ,wax even garden soil! Experiment and have fun.

  • Did you just use normal plaster of paris or anything more added to it?

    Can you tell the proportion of plaster and water?

  • where do you get plaster from please tell

  • @pbadgermw I used to get frustrated, only getting to use a 1/4 to half of a 5kg bag of it, even when I kept it in an old refrigerator... so I now keep my extra plaster in a 2.5 gallon bucket with a locking seal type lid and it stays fresh for a very long time... :D

  • @Flashistic atually you can use old plaster but when it gets like that you have to sift it to get the larger bad bits out

  • I hope you make more videos. I found your teaching quite helpful. All best, ND
