Neftaly Pottery Workshop – Day 2: Pottery Creation and Firing Process
Day Overview:
On Day 2, participants will engage in hands-on pottery creation using hand-building techniques learned on Day 1. The focus will be on shaping, molding, and refining pottery pieces, followed by an introduction to the ceramic firing process—what happens to clay in the kiln, and why firing is essential.
1. Pottery Creation: Crafting First Pieces
Objective:
Enable participants to apply their foundational knowledge by creating a functional or decorative clay object using hand-building techniques.
Activities:
Review and Demonstration:
Brief recap of pinch pot and coil building.
Instructor demonstrates combining techniques to make more complex forms (e.g., a lidded container, mug, or vase).
Emphasis on design planning: setting intentions for function, form, and decoration.
Participant Hands-On Work:
Participants begin shaping their own clay projects using:
Pinch method for bowls or cups.
Coil method for vases or cylindrical forms.
Optional: Slab-building technique for flat-sided pieces (e.g., boxes or plates), introduced as a new concept.
2. Techniques for Shaping, Molding, and Smoothing
Objective:
To guide participants in refining their clay forms for structural integrity and aesthetic appeal.
Key Techniques Taught:
Shaping:
Compression of bases to prevent cracking.
Maintaining even wall thickness for stability during drying and firing.
Using supports (foam, molds, or forms) for shaping consistency.
Molding:
How to shape clay around or inside basic molds (e.g., bowl-shaped plaster molds or containers).
Creating handles or attachments (like spouts or feet) using score-and-slip method.
Smoothing & Finishing:
Smoothing surfaces using fingers, rubber ribs, and sponges.
Refining edges and joining seams securely.
Introducing texturing tools for optional surface design.
Instructor Tip Sessions:
How to fix minor cracks or air pockets.
Identifying signs of weak construction.
3. Introduction to the Firing Process
Objective:
To give participants a clear understanding of how pottery is transformed from soft clay to a hardened ceramic piece through firing.
Topics Covered:
a. The Stages of Clay Drying:
Leather-hard stage: firm but carvable—ideal for refining shapes and adding detail.
Bone-dry stage: completely air-dried, very fragile—ready for bisque firing.
b. Kiln Basics:
What is a kiln?
An insulated high-temperature oven used to fire ceramics.
Types of kilns:
Electric (most common for studio use)
Gas-fired
Wood-fired (traditional method)
c. The Firing Stages:
Bisque firing:
The first firing, typically at lower temperatures (approx. 900–1000°C), hardens the clay but leaves it porous enough for glazing.
Glaze firing:
The second firing after glazing. Fuses glaze to the piece, sealing it and adding shine or color. Temperatures vary based on clay and glaze type (up to 1300°C).
Visual Aids/Demonstration:
Show pre-fired vs. post-fired pieces.
Present firing schedule example (temperature ramp-up, soak time, cooling phase).
Display a bisque-fired piece and glazed version of the same item.
4. Kiln Safety and Firing Prep
Objective:
Ensure participants understand the safety considerations and responsibilities when preparing work for firing.
Safety Guidelines:
Clay must be bone dry before entering kiln to prevent explosions.
No trapped air pockets—proper wedging and construction are essential.
Pieces should not be too thick or uneven to avoid cracking.
Preparation Steps:
Cleaning bottoms of pots to prevent glaze from sticking to kiln shelves.
Labeling and handling pieces with care.
Loading kiln: overview of shelf stacking, space for air circulation, and supporting fragile items.
5. Closing and Day 2 Wrap-Up
Participants place finished works on designated drying shelves.
Instructor outlines the expected drying and firing schedule.
Preview of Day 3: Glazing and Surface Decoration Techniques.
Reflection & Discussion:
Participants share thoughts on their first creation experience.
Encouraged to sketch glaze ideas for their bisqued pieces.
Open Q\&A for further clarification on kiln processes.
Optional Take-Home Practice:
If possible, participants can take home small slabs or sample clay to practice textures or build small items for future projects.
