I use many different chemicals for my experiments. Some are common ones like sugar, salt or baking soda. Others are less common, like coppersulfate, red prussiate or sodium thiosulfate. To be able to make good crystals, it's important to know the properties of the chemicals you work with. Although this information can be found easily on the internet, it is often wrong or fragmented. For the following chemicals I have put together a list of properties and some extra information about its history and it also comes with some photos from my own collection.
