This module focuses on applying learned techniques through structured experimentation and creative execution.
A. Creating Test Tiles for Experimentation
Purpose: Test glaze interactions, textures, and firing results before committing to final pieces.
Methods:
Grid Testing: Apply different glaze combinations on a single tile (e.g., Layer Glaze A over Glaze B).
Texture Tests: Add sand, grog, or silicon carbide to sections.
Firing Variations: Fire tiles at different temperatures or schedules (e.g., oxidation vs. reduction).
Documentation:
Label each section with glaze codes (e.g., G12 = Cobalt Blue + Rutile).
Photograph results and note observations (crawling, color shifts).
B. Designing a Finished Piece with Advanced Techniques
Process:
Plan: Sketch the design, marking glaze layers, resists, or carving areas.
Execute: Combine 2+ techniques (e.g., wax-resist patterns + spray gradients).
Fire Strategically: Account for glaze run (e.g., place on stilt if glossy).
Example Project:
Celadon Vase with Sgraffito:
Apply wax resist, carve vines, then dip in celadon glaze.
Fire in reduction for blue-green translucency.
A signature palette distinguishes your work and ensures consistency.
A. Recording Recipes and Results
Glaze Journal Template:
Recipe: Ingredients (e.g., 50% feldspar, 30% silica).
Application: Dipping thickness, layers.
Firing: Temp, schedule, atmosphere.
Outcome: Color, texture, defects (photo attached).
Digital Tools:
Apps like Glazy or spreadsheets to track variables.
B. Custom Mixing for Unique Finishes
Blending Commercial Glazes:
Mix 70% Matte Base + 30% Transparent for semi-matte.
From Scratch:
Start with a base recipe (e.g., cone 6 transparent), then:
Add 5% copper for green.
Replace 10% feldspar with dolomite for matte.
Experimentation:
Test small batches (100g) before scaling up.
Test Tile Matrix:
Create a 4x4 grid testing layering (e.g., Shino over Tenmoku).
Signature Piece:
Craft a mug using three techniques (e.g., mishima, underglaze, overglaze luster).
Glaze Diary Entry:
Record a custom recipe’s results, including unexpected outcomes.
Pro Tips:
Recycle Failed Tests: Crush tiles for grog in future clay bodies.
Share Findings: Swap glaze logs with peers to discover new combinations.
