| Potassium nitrate, also known as niter or saltpeter, has been used to preserve meat and is found in toothpaste formulated for sensitive teeth. |
| The German U-boats were shooting on the boats, so most of the niter they were trying to import to make nitroglycerin was at the bottom of the ocean. |
| The British blockade had made the importation of niter from overseas impossible. |
| One-dram doses of nitrate of potash or 1-ounce doses of sweet spirits of niter are useful in the drinking water. |
| To burn well the paper should first be impregnated with an aqueous solution of niter and dried. |
| In historical memory the first niter to bear this name was Perot the Victorious. |
