English: Pure titanium tetrachloride at its triple point, inside of an airtight glass flask. All three phases are present: solid crystals are melting and have sunk in the liquid, while the rest of the flask is filled with gaseous TiCl4 (invisible).
Some moisture from the ambient air has condensed on the outside of the flask, near the bottom.
