EM 217 or Wed clay has become quite popular in the film industry for creating large detailed sculptures and has been largely used on the seasons of Face Off. Although it is a water based clay, Wed clay dries more slowly and has many of the same sculpting qualities of oil based clay. Requires a spray bottle of water for maintaining moisture and for smoothing. Can be used for mask sculptures as well. Wed clay is not considered reuseable.
One package of WED clay weighs around 11,360kg.
