| 11. | This oxidised the lead to litharge, troy ounces of silver per ton of lead ( 178 ppm ).
|
| 12. | It is associated with cerussite, galena, litharge, massicot, mimetite, native lead, and wulfenite.
|
| 13. | During the Middle Ages, litharge _ a white oxide of lead _ was added to wine as a sweetener.
|
| 14. | The most notable driers are litharge, sugar of lead, patent driers, sulfate of zinc and manganese dioxide.
|
| 15. | Cupellation involved removing the lead from a silver-rich alloy by oxidising the lead to litharge, leaving the silver behind.
|
| 16. | The process begins when the crystal mix _ silica sand, potash and litharge _ is transformed into molten crystal in huge furnaces.
|
| 17. | After the litharge has been absorbed by the cupel, buttons of silver were formed and settled in the middle of the cupel.
|
| 18. | To secure the prisms of the lens a compound of calcium carbonate, lead, and linseed oil, called litharge, was used.
|
| 19. | If deterioration of the litharge is found, it is likely that the prisms are not properly secured within the frame structure of the lens.
|
| 20. | In powdered tetragonal litharge form, it can be mixed with linseed oil and then boiled to create a weather-resistant sizing used in gilding.
