PCB Etchant. You are purchasing 4 Ounces (by weight) of Printed Circuit Board Etchant. This etchant remains clear as it dissolves the copper from the board so you can monitor the etching process (unlike Ferric Chloride solution, which turns black).
This is my second bottle of this product and this particular bottle did not work as well as the first bottle. After about 30 minutes, crystals started to form on the board being etched and those crystals blocked areas of the board from being properly etched. My first bottle of this product did not have this problem and all boards etched with the first bottle came out perfect.
