It's Kalium-Aluminium-Sulfat, which falls out as crystal, when in heated water-bath and food-colour. It takes a while and needs re-bathing/heating - but once I have grown something nice - I will follow up:
Simple precipitation, ditch the kit and put table salt in hot water until it doesn't dissolve anymore. Add some food colouring and you've got coloured crystals!
