# Industrial Specification: Ceramic Glass Cooktop

## 1. Technical Definition
The flat, heat-resistant glass surface of an induction cooktop that provides the cooking interface.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **20-550°C**. Failure boundary: **570°C (glass transition temperature of ceramic glass)**, Mechanism: **Thermal stress-induced microcrack propagation due to coefficient of thermal expansion mismatch between ceramic glass (α=3.2×10⁻⁶/K) and underlying heating elements (α=16×10⁻⁶/K)**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the primary material used in ceramic glass cooktops?
**A**: Ceramic glass cooktops are primarily made from specialized ceramic glass, typically Schott CERAN or similar materials, which offer excellent heat resistance, durability, and a smooth cooking surface.

### Q: How does the heating zone work on a ceramic glass cooktop?
**A**: Heating zones on ceramic glass cooktops use induction technology to generate heat directly in compatible cookware. The ceramic glass surface remains relatively cool while transferring electromagnetic energy to the pot or pan for efficient cooking.

### Q: What are the key components in a ceramic glass cooktop BOM?
**A**: The main components in a ceramic glass cooktop bill of materials include the Control Panel Area (for user interface), Edge Sealing (for safety and aesthetics), and Heating Zones (induction elements beneath the glass surface).

## 6. Manufacturing Compliance
- ISO 8442-1:1997 (MATERIALS AND ARTICLES IN CONTACT WITH FOODSTUFFS)
- CE MARKING (EU DIRECTIVE 2014/35/EU FOR LOW VOLTAGE EQUIPMENT)
