What mineral burns with a blue flame?
The element boron produces a lovely green flame, as long as you avoid contamination with sodium which has a bright yellow flame that tends to overwhelm other colors. Boric acid is a conveniently available boron compound. You can mix it with alcohol and burn it. Very lovely. But of course, be safe. Fire can spread if you do not handle it with care.

Why is a lithium nitrate flame and a lithium chloride flame the same color?
Lithium nitrate and lithium chloride flame tests produce the same color because it is the lithium electrons that are raised to a higher energy level and then drop back down to their ground state. Any ionic compound containing lithium will give the same results. Flame tests are used to show the color and spectrum of the element as its electrons are raised to a higher energy level and then fall back to their ground state.
How do impurities affect the outcome of the flame tests?
The result can be erroneous.
Why can you not use flame tests to identify all the elements?
