After the handles have been attached the mugs are left to slowly dry overnight. The next day they are trimmed while the clay is still soft enough, but not too soft, but strong enough so they are strong enough to be trimmed.
When I have finished turning them I generally wipe where the handles joins the body. This is to make sure there is a smooth join and no sharp areas which would later make the handle uncomfortable to hold.
They are then left to thoroughly dry before going through their first 'bisque' firing at a temperature of 1000 degrees Celsius.
