Ceradel Frit C 1249
Alternate Names: C1249 Fritte, C 1249 Fritte, Ceradel Frit 1249,C-1249
Description: Lead bisilicate frit, Bisilicate de plomb
| Oxide | Analysis | Formula | Tolerance |
|---|---|---|---|
| PbO | 70.00% | 1.00 | 20 |
| SiO2 | 19.00% | 1.01 | 10 |
| B2O3 | 11.00% | 0.50 | |
| Oxide Weight | 318.86 | ||
| Formula Weight | 318.86 | ||
Notes
Similar to a lead bisilicate, but with significant boron.
We have another source that says this is just a lead bisilicate. So the analysis is uncertain.
