I was wondering why cannot boiling chips be reused.
As far as I know, they are microporous materials, often coated with PTFE.
They work by, I suppose, giving the heated substance a small cavity, in which a phase transition is favored.
Yet, the golden rule of boiling chips is: they cannot be reused.
I was wondering why they cannot be treated the way dessiccant materials (for instance, molecular sieves) are used, for instance by washing them after use and driying them in oven (especially when non-dangerous materials are involved).
