I believe that most of the time when we don’t have a good result, it is not because we didn’t use the right product or formula it is because the piece was in a different stage of dryness. Below are some simple ways to understand the stage of the clay when you make a piece.
|Characteristic||Stage of the clay|
|wet, but not sticky||Leather Hard Soft|
|feels cool and stiff||Leather Hard Stiff|
|room temperature ready to fire||Bone Dry/Green ware|
The perfect stage of clay to fix a crack or join together is leather hard soft. To return from leather hard stiff to leather hard soft you have to cover the piece with a wet paper towel then cover with plastic , then wait a least 1 day.
But you have to remember if your piece is bone dry/greenware it is not easy, it will be require a lot of patience to return your piece to earlier stages. Sometimes when I try to wet the piece and cover it with wet paper and plastic for one day it is not enough, I have noticed the surface is wet but not the internal part, especially if it is thick. You have to repeat the process again until the piece is leather hard soft.
