Heartshome Posted March 19, 2018 Share Posted March 19, 2018 Dose anyone remember their Gran having a container of 'COAL CRYSTALS'. My Gran had them in an up turned glass jelly mould, on top of her big radio, sat on a cupboard. ( I guess out of the way of little fingers ) Every so often she would get them down to 'feed them', she used an Eye Dropper, with some sort of liquid in, which I was allowed to drip over the Crystals, then we put drips of Red and Blue ink on the top. A couple of weeks later, we would get them down to find more beautiful Pink and Violet Crystals had grown from the coal in the bottom. It always fascinated me how it happened.

Hopman Posted March 20, 2018 Share Posted March 20, 2018 I'd not heard of it myself, but take a look at https://www.education.com/activity/article/Colorful_Crystals_Coal/ Link to comment Share on other sites More sharing options...
Athy Posted March 20, 2018 Share Posted March 20, 2018 Blimey, you've revived a VERY distant memory. I think that when I was at Gleadless County School - and probably still in the infants - one of our teachers had a jar of them in the classroom. Or it may hav ebeen one of my numerous Aunties in her house. Certainly I was still very small at the time. Link to comment Share on other sites More sharing options...
Heartshome Posted March 20, 2018 Author Share Posted March 20, 2018 Hia Hopman, thanks for the info, glad the idea hasn't died out. Hi Athy, yea, I was about 7 when my Gran first showed me them around 1959/60. Never saw them again anywhere. Link to comment Share on other sites More sharing options...
