Iv Av 2 Advanced Trial Glass Atelier Work |top| Instant
This report assumes the context of an architectural or craftsman curriculum (common in technical high schools or vocational colleges), where "IV AV 2" refers to a specific curriculum module (Unit 4, Assessment 2) and "Atelier Work" implies hands-on studio practice.
Materials & equipment
- Glass: soda-lime, borosilicate, lead crystal (as allowed), sheet glass (float), frits, powders, cane, rods.
- Furnaces: glory hole, main furnace, annealing kiln, small kilns for fusing/slumping.
- Tools: blowpipe, punt, tweel, jacks, wooden blocks, graphite paddles, bench tools, bench torch for lampworking.
- Cold shop: glass saw, wet wheel, belt sander, diamond pads, cerium oxide, polishing lap, diamond drill bits.
- Surface: sandblaster with media, respirators rated for silicates, acid-etch setup (if permitted), enameling kiln, lusters, cold-applicable adhesives.
- Safety: heat-resistant gloves, face shields, safety glasses, leather clothing, ventilation, first-aid, kiln gloves.
- Misc: steel armatures, wood/metal mounts, LED lighting systems, adhesives (epoxy rated for glass), release agents.
3. Materials and Equipment
- Glass types: Soda-lime soft glass (e.g., soft art borosilicate alternatives) and borosilicate tubing/rods (3–10 mm diameters).
- Frits and colorants: transparent clear, lead-free opaque, and selected effervescent/metallic reagents.
- Fuel/oxygen bench torch (propane/oxygen or natural gas/oxygen) for lampworking.
- Glory hole and small bench furnace for reheating.
- Programmable glass kiln (up to 1200°C) with digital controller for annealing and kiln-forming.
- Annealing lehr or kiln schedule capability.
- Cold-working tools: diamond saw, silicon-carbide wheels, wet-polish pads, cerium oxide.
- Measurement: digital calipers, micrometer, refractometer (if optical index needed), polarized light viewer for strain.
- Safety: ventilation/hood, eye protection (UV-filtering glasses), heat-resistant gloves, respirator (for powders), first-aid.
2. Objectives
- Quantify dimensional variance across repeat runs (target ≤ ±2%).
- Reduce surface defects (devitrification, pitting) by at least 50% relative to baseline.
- Validate hybrid-process join integrity (mechanical strength and optical continuity).
- Document stepwise procedures enabling reproducibility among technicians.
