Module 4: Glass Engraving and Finishing

Duration: 3 hours | Microcredential: MCCPDL-U12M4-v1.0

Module Overview

Module 4 covers glass engraving techniques (rotary, sandblast, acid etch, and laser) and finishing methods (fire polishing, edge work, and surface treatments). Students learn to apply decorative and functional surface modifications to glass pieces, select the appropriate technique for different design requirements, and achieve professional-quality finishes.

Learning Objectives

1. Operate a rotary engraving tool to create controlled line work and surface textures on glass
2. Apply sandblast masking and carving techniques to produce etched designs with depth control
3. Understand acid etching chemistry, safety requirements, and application methods
4. Identify appropriate laser engraving parameters for different glass types
5. Apply fire polishing and mechanical edge finishing techniques to produce finished pieces
