Using Boiling Chips when Distilling

If you're heating your still over an external heat source, then you should have a couple of boiling chips inside it to help break the boil. These are any rough-surfaced, inert object - like bits of broken pottery (unglazed so as to avoid lead based glazes), broken glass, or even a couple of marbles.

The rough surface acts as a site where the bubbles can start to form easier. If your pot is nice and smooth on the inside, then its difficult for the bubbles to form, and you can end up super-heating the liquid. When it does boil, it might be quite violent, and give surges of vapour up the column, ruining that nice equilibrium you're trying to create. Boiling chips, although making the job a little noisier (rattle like hell!), do help give a smoother simmer.
