Labstone Type III – Yellow 50 lb Box

Labstone is a premium Type III dental gypsum stone formulated for general laboratory work — articulations, denture flasking, master models, and repairs. The thixotropic mixture pours with smooth, flowable consistency and hardens to a rigid, dimensionally stable cast suitable for everyday model work.

Key Features

• Type III gypsum (yellow / buff) — all-purpose model stone
• Thixotropic formulation — smooth flowable mixing, fast pour into impression molds without trapping bubbles
• Strong mechanical properties — rigid set casts that resist abrasion during trimming and articulation
• Fast set time — initial set in 8–10 minutes for efficient workflow
• Consistent, predictable results — reliable expansion and compressive strength batch-to-batch
• Easy handling — flows smoothly, blends quickly, low foam
• Yellow color — high contrast against typical impression materials
• 50 lb (≈ 22.7 kg) box — laboratory bulk size

Indications

• Articulating models for occlusal analysis and treatment planning
• Flasking acrylic dentures (full and partial)
• Pouring crown & bridge master models (basing)
• Repair and remount models
• Custom tray fabrication and study models

How To Use

1. Measure powder and water per the recommended water/powder ratio on the box label (typically ≈ 30 mL water per 100 g powder for Type III)
2. Add powder to water, hand-spatulate to wet, then vacuum-mix for 30 seconds
3. Pour into impression on a vibrator within working time (~3–5 minutes)
4. Allow initial set 8–10 minutes; full set ~30 minutes before separating from impression
5. Trim and articulate; finished model is ready for laboratory work
