It is almost mother's day and Lola would like to make something special for her mom. She desides to make a home-made ceramics vase. Lola goes to ceramics class in her school to make the special gift.
The teacher tells Lola that the first thing she has to do is wedge her clay. Wedging is the process of getting air bubbles out of clay.
"If air bubbles are left in the clay, your project will blow up in the kiln Lola", says the teacher. "Trapped air causes ceramics projects to blow up."
Lola uses a rolling pin to roll a flat slab of clay. Lola cuts a circle into the slab for her base.
Lola rolls several coils for the first layer of her vessel. Rolling coils is the easiest method in building a ceramics project.
Lola adds spiral coils.
Lola's techer tells her that to attach the coils she must use the technique score, slip, and knit.
Scoreing is the technique of carving small slits in the clay so that the coil will attach to the base easier. The tool Lola will use to score could be a plastic fork or the pointy end of a modeling liner.
Sliping is the technique of adding wet, sticky clay to the coil. It holds the coil in place.
Kniting is the techinique of smoothing back and fourth between the coil and the base after you have attached the coil. You can also use the opposite end of the modeling liner for this technique.
Lola does a layer of vertical coils and a layer of horizonal coils. She smooths as she goes.
Lola does a layer of negitive detail using the ribbon tool.
Lola makes a layer of additive detail by adding vertical rectangles.
Lola believes her project is finished. She puts the finishing touches on her project, such as smoothing and cleaning up clay boogers.
Lola's project is now greenware. Greenware is the state a project is in beofre it goes through the kiln. It will dry on the shelf for two weeks before she cane fire it in the kiln, a large oven used to process ceramic projects.
The techer will bisque fire Lola's project at cone 04/1940 degees ferenhiet. This is the appropriate temperature for a ceramic project to be fired.
Two weeks later, Lola's project has come out of the kiln and is now in the bisqueware state. That means Lola's project is almost complete. All she has left to do is glaze it.
Lola sands the rough spots and rinses the project to eliminate clay dust from the kiln.
Glazing, is pretty much the process of painting a ceramic project. Lola desides to choose all sorts of colors for the vessel. Lola's project is now glazeware, the state a project is in when it has been glazed but needs to go through the kiln one last time.
After Lola glazes the project her teacher glaze fires it through the kiln. This time the kiln must be fired at cone 05-06/1915 degrees ferenhiet. This is the temperature you always use when you put glazeware through the kiln.
Lola now has a beautiful home-made functional vase for her mother. Lola's mother could not be more proud.
