Seams
Do not try to remove the seam line from a piece of greenware all in one pass. It is best to go over the line several times until the line is flush with the rest of your piece.
After the bulk of seam lines have been removed with a tool, the next step is to sand the lines with a sander sponge.
The final step in cleaning is to sponge your piece lightly with a damp sponge. This will guarantee smooth greenware and remove excess dust.
The only exception to the sponging technique in cleaning greenware is when you plan an antique wash on the finished bisque. The antiquing colour may concentrate in sponge marks.
If, after cleaning, you see detailed areas that are not clear from either a bad casting or from your cleaning, they should be scribed or carved back into the greenware.
Remember that the bottom is a part of your piece too! The same care should be taken in cleaning this area of greenware.
Be sure to test how well your piece of greenware sets on its base. By cleaning the bottom effectively, you finished piece will not wobble.
A piece of sandpaper attached to a table top is an effective aid in leveling the bottoms of greenware pieces.
After you have completed cleaning a piece of greenware, set it aside for a couple of hours and then go back and inspect it for anything you may have missed.
