Blue Crystal Growing Set \ Kit with Alum (Aluminium Potassium Sulphate) NEW
kitchen-chemistry is proud to present a fully revised and updated crystal making set
which encourages students to do extra research at relevant points extending the reach of the subject into the GCSE curriculum. It consists of:
200g of pure Alum
1 Sachet Brilliant Blue Dye
Easy to follow Instruction Sheet
Polypropelene Stiring Spoon
Wooden Splints
Reel of Cotton
Seed Crystals x 2
A fascinating hobby combining the beauty of crystals, in this case fantastic translucent blue, and the amazing science of crystal formation.
Using this method, the crystals are grown on a length of cotton suspended into the alum.
An impressive bag of 200 grams of Alum allows you to make a large crystal similar to that shown in the first picture with some perseverance,
whereas many of the other retail kits skimp on the Alum supplied.
The only additional equipment you need is a pyrex jug or bowl and you may need adult supervision when dissolving the alum on a stove.
Hundreds of great feedbacks for this item.
This set is available in Blue or Red crystal colour. You can also produce white translucent crystals with either kit.
We offer discounted postage on multiple purchases (when using shopping basket).
