| A bitter taste and squeaking under a rotating knife-point indicate that some of the red layers contain sylvite. |
| The most common minerals of chlorine are halite, or rock salt, sylvite, and carnallite. |
| Water decomposes kainite to epsomite and sylvite. |
| In association with our work with the American Chemical Society, we have developed a field procedure for distinguishing halite from sylvite. |
| When the solution reaches one-tenth the volume of the original, more soluble minerals like sylvite and halite form. |
| It occurs naturally as the mineral sylvite and in combination with sodium chloride as sylvinite. |
