I had to get ready for the laboratory quickly and ordered it because it was available quickly. But it's not like the boiling chips I'm familiar with, ceramics with vapor permeable holes that provide multiple nucleation sites for gas-liquid equilibrium. I sent it back for a refund. And kind of pricey for a plain marble rubble.
