Most mathematical notation is designed with handwriting in mind in the first place, and typography must then try to follow, not always very successfully. However there is a particular type of notation that is, to me at least, is more easily done in print than in handwriting: this is the "gothic" or "fraktur" type, typically used to denote Lie algebras, e.g. $\mathfrak{g}$ or $\mathfrak{h}$, or $\mathfrak{su}(2)$ or $\mathfrak{so}(3)$ etc. So my question is, how do you differentiate these object in handwriting, e.g. with a chalk on a blackboard? How should one write these types of letters, to distinguish the "gothic" $\mathfrak{g}$ from an ordinary $g$?
