Glass’s theoretical strength (~7,000 MPa) far exceeds practical values (35‑70 MPa) due to surface microcracks. Five strengthening methods—hardening, chemical stabilisation, homogenisation, stress relief, and design—combined with precision edge machines (double‑sided, polishing, miter, bevelling, CNC) and post‑treatments like tempering and microcrystallisation, can multiply strength up to 18‑fold. Glass thus becomes a robust material for construction, transport, electronics, and aerospace.

China's glass machinery, after 40 years, exports more than imports. Shunde leads cold‑processing. Solar and green building boost demand. Key machines: edgers, double‑sided, CNC centers.

Bifacial PV modules are the future. Lightweight glass and advanced processing equipment—horizontal double edgers, single polishers, 45° miter machines, CNC centers, and automatic drillers—enable the transition. Tight supply supports a multi-year upcycle, while smart processing drives long-term competitiveness.

Glass basics cover visible transmittance, reflectance, solar properties, U‑value, shading coefficient, and thermal stress. Specialty glasses like heat‑reflective, one‑way, and electromagnetic shielding serve unique roles. Proper processing turns them into efficient, safe, and beautiful windows, doors, and curtain walls.
