Morphology

unannealed = annealed (transparent) = un + anneal + ed

The negative prefix 'un-' is applied to the adjective 'annealed' in a standard way to mean 'not having been annealed'.

Etymology

Unannealed is made of un- 'not' plus annealed, which comes from a word meaning to 'heat and cool' metal or glass to make it softer and less likely to crack. So, unannealed describes material that was not treated that way and is therefore hard and more likely to break.
