The ingredient jars refers to a set of puzzle items from Amnesia: The Dark Descent. They are combined in the Chemistry Pot and used to dissolve the Shadow's residue blocking Daniel's path through the castle.


The ingredient jars are small, dark glass bottles, plugged with corks, sporting paper labels. All of the jars are located in the Wine Cellar. The jars are distinct items, but all are represented by visually indistinguishable icons in the inventory.


There are four separate ingredient jars, each containing a different substance necessary to create the acid. Their names and respective descriptions are as follows:

  • Aqua RegiaA jar of Aqua Regia.
  • CalamineA jar of Calamine.
  • CupriteA jar of Cuprite.
  • OrpimentA jar of Orpiment.


  • The four ingredients are real chemical compounds.
    • Aqua Regia is comprised of hydrochloric and nitric acid (the latter is also known as "aqua fortis") and is one of the few known acid compounds capable of dissolving gold and platinum, metals known for their chemical resistance.
    • Calamine is the historic name for zinc carbonate and zinc silicate, now known as "smithsonite" and "hemimorphite" respectively. The best known use for this compound is in calamine lotion, used to treat skin irritation.
    • Cuprite is a crystalline ore of copper from which copper (I) oxide forms. Cuprite has the capability to grow into crystals of gemstone quality, albeit few locations of occurrence are known.
    • Orpiment is a highly toxic compound comprised of arsenic and sulfur that forms near volcanic sites in crystalline form. It was used as pigment in paintings, as medicine, as poison for insects, and to create poison-tipped arrows.
  • The acid used to dissolve the Shadow's residue could have possibly been done solely by the aqua regia and (possibly) the orpiment as they are the most hazardous to biological matter.
