Making pottery is an art and I beleive packing pottery is an art as well. Packing individual pots is not that hard. You can bubble wrap it and put it in a box full of peanuts. But for wholesdale orders, multiple pots need to be packed together. You want to pack efficiently so you can fit several pots in one box and at the same time make sure it is not so tightly packed that the pots hit against each other and break.
Also keep in mind that you can get bigger and bigger boxes to pack more and more pots. I don't recommend that, because if the box is large and awkward, the likeness of it being dropped is higher. I usually use two sizes 17"x13"x13" and occasionally a 18"x18"x16" box. Of course this depends on your size of pieces and the number of pieces you need to ship in every order.
First the tools of the trade.
A good heavy duty packaging tape
Stretch wrap. This is my life saver. I couldn't live without this stuff.
A good blade
Bubble wrap (Use recycled only if it is in good condition)
Packing peanuts (I use recycled clean peanuts that I get from a local electronic store)
I wrap each piece (in this case my mugs) in bubble wrap. Then using stretch wrap I wrap pieces together with cardboard in between them. This way the pieces don't touch and have a cardboqrd buffer in between. The stretch wrap is wrapped tightly to make sure the pieces don't move.
With 2 inches of peanuts in the bottom layer of the box, the mugs are placed with enough room on the sides and between the two packs of mugs. Then pack peanuts around the corners and edges with another layer of peanuts and more mugs.
I am sure every potter/artist packs their work in their own way. I would love to hear of more ideas you have and what works for you. Do comment and share with your social networks.
