Continuing our new series of chemical recipes, we bring you week 12 – ammonium dichromate ((NH4)2Cr2O7).
Remember that when preparing any of our recipes, you should always wear appropriate PPE.
What is ammonium dichromate?
With a bright orange/red crystal appearance at room temperature and pressure, ammonium dichromate is used within pyrotechnics, lithography, leather tanning and oil purification. It is thermodynamically unstable and highly toxic. When ignited, a green residue is produced.
