Handleiding

Here is information about handling the

substance contained in this kit.

Please note the following hazard and

precautionary statements for the

chemical contained in this kit:

Potassium aluminium sulfate (alum):

Avoid breathing dust. Do not get in eyes,

on skin, or on clothing.

Warning. The following applies to all

chemicals: Store locked up. Keep out of

reach of children.

This primarily applies to young children,

but also to older children who — unlike

the experimenter — have not been

appropriately instructed by adults.

Also follow this precautionary statement:

IF SWALLOWED: Get immediate medical

advice/attention and have product

container or label of chemical substance

at hand.

If any chemicals inadvertently get onto

the skin, rinse off immediately under

running water. Always be careful not to

inhale chemical dust or powder when

experimenting.

Information about hazardous substances

To open the crystal salt packet, cut

the packet open at one corner with

a pair of scissors. Never use your

teeth. Be sure that the printing on the

packet remains legible.

If the crystal salt has formed

clumps, it does not mean there is

anything wrong with the quality

of the contents. It means that some

moisture has gotten in. This will not

affect its function. The age of your

crystal salt will likewise make no

difference.

Advice for growing crystals safely

Cleanliness is especially important

in chemistry. So always clean up any

used containers and your workplace

immediately after ﬁnishing the

experiments. Then wash the

containers with clean water and dry

them with a paper towel, which you

should then throw into the trash.

Since you will only be working

with small amounts of a harmless

chemical, you can just wash liquid

waste down the sink with plenty of

water. Solid waste can go into the

household garbage.
