Handling and safety
Dry ceramic materials generate respirable silica dust. Use a NIOSH-approved N95 or P100 respirator and adequate ventilation when mixing dry, and wet-clean surfaces.

Questions
- How much Ferro frit 3124 do potters use in a glaze?
- Across 675 published glaze recipes containing it, the typical amount is 30% of the dry batch, with half of recipes between 13.2% and 45%. Colorants and additives sit far lower than fluxes and glass formers; treat these as a range to test around, not a target.
- What cone is Ferro frit 3124 used at?
- It appears in recipes across the range; the most common cones among published recipes are cone 6, cone 04, cone 5. Where a material sits depends on the rest of the recipe more than on the material itself.
- Is Ferro frit 3124 safe to use?
- It carries no specific hazard flag beyond the general rule for all dry ceramic materials: avoid breathing the dust and read the supplier's SDS.
