Your videos are great! I was just looking for how to make a plaster board, and got a bonus lesson on a damp box! I’m moving from clay sculpture to pottery but plan to add sculptural elements to pieces. The damp box will be more useful than my current method of damp cheesecloth & layers of plastic method to prolong drying. (My method is useful for larger/heavier/oddly shaped pieces though)
Thanks Ann. You are always full of knowledge! Appreciate your help!
Hi Michele. Thanks for commenting. I am glad you found it helpful!
Great video. My new damp box is a game changer!
This was an AWESOME video! Thank you VERY much for taking the time to create
Such a helpful video! Thank you!
Always great info from you
As always - GREAT video!
2nd. title for this could be :"Happy hands play in mud like substance."
I have a damp box and use my canvas covered concrete table for recycling. Too concerned I would break the plaster.
Thanks for sharing this method with the superb teamwork at shaking all over.
I like your titles much better, haha Freddie. That concrete idea is a great one. Thanks for the tip!!!! You are so clever
Thanks
This is an amazing video, thank you! Can I ask what sort of mixer/drill attachment you use to mix your reclaim?
I use this one:

@@LittleStreetPottery Thank you!
Hello Ann,
Thanks for the wonderful video! I've already bought your how-to to paint Birds video and I think this is beautiful compliment with all these help classes on TH-cam 🥰
I did have a couple questions though, first of all do you use any kind of soap like diluted dawn to wash the slabs once you've made them ?
I'm thinking how do you get the Vaseline off of them without something to break the oil down?
And once the box is created do you put water in the bottom of it along with the plaster slab?
Occasionally or at the beginning or keep a fill to line of water in it?
🤔 How does the moisture stay in the box and where does it come from?
I understand the plaster would initially have moisture trapped in it from the cleaning process...but I would think at some point it would dissipate?
Or once you put the pottery in there with the plaster Paris slab does it draw the moisture from the pottery that being the only moisture in the Box?
Or does it just equalize the moisture in the pottery from the moisture that is already in the pottery?
No additional moisture needed?
I think I'm a little lost on this one 😆
Any clarification would be greatly appreciated 😁
Wow, thank you so much first for purchasing the birds video but also for watching the You Tube videos. You are awesome!!! As far as the vaseline goes, I havent had to use any soap to get the vaseline off the slab. I am not sure if the plaster soaks it in but it has not been a problem. I wouldnt use dish soap on the plaster slab for fear it would soak up the suds into the plaster. Like I said I havent tried it, but I suppose there is the possibility the plaster could suds up the next time you put it under the faucet. If. you want to clean out the storage container with the dish soap, you can go for it but thoroughly rinse out the soap before putting the slab back into it.. .... If the vaseline does get onto your clay, it is not a problem. It will fire out in the kiln and you will be able to glaze with no problem.
@@annruel1982awesome thanks for your personal response ❤
Can I use No 1 pottery plaster or does it need to be plaster of Paris to make a mold?
Hi Michele. Pottery Plaster is supposed to be stronger than Plaster of Paris and should work great. The thing for me is that I think you have to purchase it in larger amounts like 50 pound bags which would cost about $20 or so. I didnt need that much plaster nor did I want to have to store extra plaster in my studio or throw out the extra plaster .
I assume you do not cover the container for the several days it takes to dry/set?
Also, someone suggested to me to get a container with a rubber seal. Is that necessary? They're not easy to find!
Love your videos and have shared with friends.
Yes, I let it sit for days until the plater sets up. I dont think you have to have a rubber seal...the one I used seemed to work just fine.
I still dont get it, the plaster has set, but what is the purpose of the chunk's of wet clay that you covered ??
Hi Lynsey. Thanks for watching. The plaster has the capability of both drying out clay and holding water in it so that when you seal it in the box with water in the plaster, the water is released from the plaster and will humidify the box. In other words when you put like reclaim clay in the box, it will soak up excess water from the clay but the clay will not completely dry out because of the humidity. Does that make sense? ... This is good for freshly thrown pieces that you want to dry slowly too.
Hi Ann
I tried it but when I touched it was like falling like powder
Why plaster of Paris not potters plaster?
I believe you can use both and I think Potter's Plaster is actually harder and better for molds. At the same time, more expensive - guess that puts me in the "I'm cheap" column. 😀
I've watch several videos and all say plaster of paris is not strong enough. Your thoughts? I made one with P of P and It has bubbles..is that ok?
Yeah, the little bubble spots are really not a big deal..the one I made in the video has some and is still working well today.
@@LittleStreetPottery thank you for your reply!!
Hello... how do you clean your red bucket? I heard that you can bend the plastic bucket to crack it or using metal tool to scrap it. However, I tried doing it to my very thin film of plaster in the bucket, any of these tricks didn't work. How would you recommend? Thank you
We don’t clean the bucket...it’s “contaminated” and really only good for plaster use. Virtually impossible to clean but would like to hear from others on how they clean or repurpose their buckets.
@@LittleStreetPottery Thank you. I assume you throw away your bucket after one time use?
@@siskawinoto we repurpose by using it for yard work (weed puller bucket) 😉
Where do you get that kind of foam? Is there a specific name for it?
I just use plaster that is purchased in most hobby, craft stores.
@@LittleStreetPottery thanks for the reply!
what about the foam? where do you purchase that?
@@soomisbreath5275 Oh, the foam was pulled from an old chair that I had :)
I also use foam that was originally purchased as a mattress pad (2"). I think you can also find it at a craft store...wish you were nearby, I just threw out another old mattress pad!
@@LittleStreetPottery you are so sweet, Ann! Thank you for the tips.
How long do you let it dry between use?
It dries at different rates based on humidity but typically I am moving pieces in and out constantly so it never really gets bone dry between uses.
@@LittleStreetPottery thank you :)
My plaster isn’t coming out of the container it was molded in! :(
Did you use the Vaseline?
