Why are mucus and glass immune to the affect of extreme acidity?

I don't know the entire reason but this may be part of the reason why: In a biological system like the stomach, there is a double mucus layer. The inner mucus layer acts as a diffusion barrier for HCL while the outer cells secrete bicarbonate which dumb the pH down to a neutral pH at the cells surface. About glass I do not know ... sorry.
