Ceramic Casserole Dish

Material Composition Assumptions

The ceramic casserole dish contains approximately 1,200 grams of material composed primarily of kaolin clay (40%, 480g), feldspar (30%, 360g), and quartz (20%, 240g). Dolomite comprises an additional 8% (96g) of the base ceramic body. The remaining 2% (24g) consists of glazing compounds including calcium carbonate and barium carbonate that provide the finished surface coating. This material combination creates the durable ceramic structure capable of withstanding high-temperature cooking applications while maintaining thermal stability.

Manufacturing Geography

Ceramic casserole dish production concentrates in China, Thailand, and Portugal due to abundant clay deposits and established ceramic manufacturing infrastructure. China dominates global production with an electricity grid intensity of 574 gCO2e/kWh, significantly influencing the carbon footprint of electric-powered manufacturing processes. Thailand serves as a major exporter to international markets, while Portugal represents European production centers. The high-temperature firing requirements make energy availability and cost critical factors in manufacturing location decisions.

Provenance Override Guidance

1. Kiln fuel type and consumption data including natural gas versus LPG usage rates and efficiency metrics for both biscuit and glost firing cycles.

2. Electricity consumption records for grinding, mixing, forming, and auxiliary processes with grid supplier renewable energy certificates if applicable.

3. Raw material sourcing documentation specifying clay body composition percentages, local versus imported material ratios, and supplier-specific extraction methods.

4. Manufacturing process specifications including kiln temperature profiles, firing duration cycles, and energy recovery systems implementation status.

5. Transportation logistics detailing shipping distances from raw material sources to manufacturing facilities and from production sites to distribution centers.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a standard 3-liter ceramic casserole dish weighing approximately 1.2 kilograms including glazing.

• Scope 1 emissions capture direct fuel combustion during firing processes which dominate the carbon footprint due to high-temperature kiln requirements.

• Scope 2 emissions reflect electricity consumption for mechanical processes including clay preparation, forming, and facility operations based on regional grid intensity.

• Scope 3 emissions encompass raw material extraction, processing, and transportation with clay mining and mineral processing representing the largest upstream contributors.

• The functional unit assumes standard household cooking applications with typical product lifespan expectations but excludes end-of-life disposal scenarios.

• Data gaps exist around regional variations in kiln efficiency, renewable energy adoption rates at manufacturing facilities, and supplier-specific raw material processing methods.
