  • In this video I show you how to make your own plaster hump, slump and casting moulds using Potter’s plaster (mine is Keramicast) which can be obtained very cheaply from your clay supplier. My bag of 25kg was approximately £28 and I have made 6 large moulds from half the sack (so more fun to be had making more with the remainder!). I hope this is a practical “how to” guide that will save you money. Hump and slump moulds are particularly useful if you want to make multiple items all the same (such as a set of mugs or cereal/pasta bowls). These can then be used over and over again by slab building.
    Hi I’m Sarah Amos. I gave up my day job and am now living the dream as a full-time potter and teacher, running courses from my studio, The Pottery Corner, in a little village just outside Chichester on the South Coast of England. With Cissy and Charlie, my studio companions, we welcome students of all abilities from complete beginners to the more experienced, teaching throwing on the potters wheel as well as handbuilding techniques.
    I love to share my clay experience and knowledge by passing on pottery techniques in my Top Tip Tuesday videos; which include full tutorials on items to try out yourselves. I also sell my work via my Website and Etsy Shop. So grab a cuppa, sit back, relax and let’s dive into what’s going on in The Pottery Corner today.

    Another great video, thanks. When you’re using a big bowl for a mould, you can tape a big plastic ball into the plaster to give you a slump mould on the inside. It also reduces the weight of the mould. Keryn in Sydney.

      Thanks Keryn - that's a great tip! They are pretty heavy to move about. The casting mould can be used both ways around - casting or slump on the inside and hump on the outside. Thanks for watching.

    Hello Sarah, thank you for your wonderfully clear and empathetic demonstrations.
    Please could you show how you drape the clay over the plaster moulds which you made in this video, I'm thinking particularly a mono-printed slab of clay,
    and also how you use the slip mould.
    Very many thanks. We beginners are so fortunate to be able to access your generously given knowledge.

    Enjoyed the video, however I will not be getting in to making molds. I use plaster to make a wet box and gave the excess to a studio as I knew I would probably find the dry plaster and dust sneaking in to other areas of my wee studio.

      Hi Debi - I made some more yesterday- double moulds for casting and hump moulds. If you use a slightly flexible plastic container - Tesco have some cheap mixing bowls/measuring jugs(about £1.50-2.00) which have a lovely shape for a pasta dishes/cereal bowls. Just remember the shrinkage amount when choosing the container. Have fun! Thanks for watching 😀

    Loved this video--- inspiring me to make plaster molds from the bowls I have in the shack---currently using as slump..but always having to use plastic wrap to slump them... I don't want to seem "dense"...but when using the plaster slumps---are you able to lay clay right on the mold? or does the plaster still need a barrier between it and the wet clay?

    • @thepotterycorner
      @thepotterycorner  Před 3 lety +3

      Hi Kd - thanks for commenting again. Once the mould is made, you don't need to use a barrier between the mould and the clay. Just make sure you use wooden tools when working against the mould. The mould is porous so it will take the moisture out of a formed skab fairly quickly (say 20-30 minutes) so don't leave it slumped for too long. Great way to make multiples. 😁

    Echoing many previous commenters; thank you for sharing your knowledge and experience with us. I’m sure there are many more hours of prep and editing that we don’t ever see and I appreciate it very much. I want to make a mold of the underside of a rhubarb leaf. If I supported the leaf with sand in a bowl-ish shape could plaster successfully mold to the leaf? Or will the leaf disintegrate in the heating and cooling process? I’d like to make bird baths and plant pots from the rhubarb mold.

  • @madmonkeystudio-ajourneyin3220

    Nice video. Thank you. Can you tell me how you calculated your volume of plaster? I know the ratio of plaster to water but not sure an easy way to calculate how much plaster I’ll need for the mould. Thanks.

    • @thepotterycorner
      @thepotterycorner  Před 2 lety

      Hiya - I measured the water in the receptacle that I was going to use first (i.e. the bowl I was going to pour the plaster into) and then used that amount of water for the mould itself. Hope that helps. Thanks for watching.😀

      @madmonkeystudio-ajourneyin3220 Před 2 lety +2

      @@thepotterycorner thank you. I was thinking along those lines but wasn’t sure about the mould with the clay mound and flower pot. IE taking that amount of space out of the calculation. But in the end there shouldn’t be a lot of waste. I find that the plaster and water together make up more volume than needed when I put the water in the vessel to measure. So many variables 😊😊❗️Watching your slip cast video. I think I’ll try experimenting with colored slip today!

    • @thepotterycorner
      @thepotterycorner  Před 3 měsíci +1

      Hi - there isn't usually plaster dust on the mold but I always wipe the mold with a damp cloth before using it just in case! The most important bit is not to use metal tools. Hope that helps. Hope you have a go.

  • @craftedsurprise4759
    @craftedsurprise4759 Před 2 lety

    Good video, thank you. Here you say that plaster will make the clay explode ... so when using the mould for Slip, at the time of removing the clay pot from the plaster mould - must the clay pot be thoroughly cleaned before finishing its drying process or after it is bone dry?

    • @thepotterycorner
      @thepotterycorner  Před 2 lety +1

      Hi and thanks for watching - If the plaster mould is dry and would haven't used metal implements on it then there shouldn't be any need to clean the pot that comes out of the mould. it is only in the making of the mould and the use of metal implements that could cause plaster to get into the clay - which would definitely explode in the kiln! Hope that helps.
