CP Storage Tips

Store cold porcelain paste in an airtight bag or tightly wrapped in plastic.    Sometimes I do both...wrap in plastic first and then in an airtight bag!

Try using a product that sucks air out of plastic bags.    Ziploc makes an inexpensive one.  There's some new ones on the market too that might work even better.


There's some new, latching plastic food storage bins on the market.  Small ones are inexpensive and claim to be airtight.  Made by Sterlite...the type with a rubber gasket to help seal.   I bought some and really like the way they latch.

Do not store really damp CP for a long period of time, this could make the paste moldy.

Store CP paste in a dry area at room temperature. Do not refrigerate, but you can freeze.

Paste that has been tinted with color will dry out faster than non-colored paste.

Don't store different colored paste in the same container if they could touch each other and transfer color.  Wrap separately in plastic wrap first.

Please comment if you have some storage tips to share!  ;-)


  1. Since I do not have much space for craft stuffI wrap up individual colors in plastic wrap and kept in an air tight container along with other colors. of course wrap it seems to be doing fine. you can try that.

  2. Thanks for tip! Wrapping tight does seem to give best results.

  3. Hi ...for how many days we can store the CP dough....Can we store the dough for longer period in the fridge....

    1. I've seen lots of comments that say not to store CP in the refrigerator but I don't know exactly why. I think if you packaged it securely enough it would be fine for a long time. Double or even triple wrap it. First wrap with a saran wrap product then put it in an airtight container. Put inside a cabinet that is cool and out of sunlight. You can also store it using one of those food storage gadgets that suck the air out of a plastic bag.Then put in container.


Thank you very much for taking the time to comment! ;-)
Sorry I had to re-instate the 'word verification'...I'm getting far too much spam in the comment box.
