Hi In page 184 of volume 4 of MC, concerning the alginate beads, it is said: Heating the beads to 85ºC / 185ºF for 10 minutes or more stops the setting process and keeps the centers liquid. Please, can you give some more information. Particularly: How do you heat the beads? After removing and washing them and in water? Can you explain why this happens? Thank you
