Vermiculite is a mineral that has very good insulating properties. It is a great way to cool down the straight lampwork beads in it. We recommend 3 liters, so the heat is stored longer. This fine grain size provided here is the standard, some makers prefer the larger/coarser vermiculite which we also retail, see in the same category.
A tip: Place the pot with vermiculite on a hot plate. It also reduces possible tensions in the beads.
