    Crystals - Alum -
  

*by T***M on Reviewed in the United States on January 1, 2019*

Easy to grow crystals .. Mix Chrome Alum = Chromium(III) potassium sulfate KCr(SO4) purple with Alum = potassium aluminium sulfate  KAl(SO4) clear .. and you can grow some beautiful crystals. Note: read the warning labels, I've had no problems, but kids should be supervised.  Once the size you like you can clear-coat them to keep them from drying out and easy to handle. Have Fun.
