Cabochon DomeFormula
Height : width ratio typically 0.6-0.7 for standard oval
Silica DustStandard
Lapidary slurry contains silica — wet grind and wear respirator.
Wet Grind Only
Keep stone wet while grinding — dry silica dust causes silicosis.
Grit Progression
Never skip grit steps — each stage removes scratches from the previous.
Eye Protection
Wear safety glasses even when wet grinding — slurry splashes at high speed.
Safety Notes
- Silica dust causes silicosis — wet grind and wear N95 respirator.
- Secure workpieces in vise — spinning wheels throw stones at high speed.
