WAD (1)
ca: FALCA (1)
es: CUÑA (1)
Wad is a small piece of refractory clay for sealing and balancing furniture when packing a kiln. It does not fuse into the furniture and can be pulled off when unpacking the kiln after firing.
Note: Wad is the same as a wedge but a wedge is fired and is made in other materials, such as wood and plastic. In Spanish and Catalan they both have the same name; “cuña” in spanish and “falca” in catalan.
