Ornate chests in Forgotten Research Laboratory and Lost Golem Manufacturing Facility

[Juryiel]

According to the wiki there's 2 Ornate chests in the lab and one in the manufacturing facility. I only found one in the lab by the Tsar weapon. As much as I enjoy the oppressiveness of these dungeons, I hate exploring in them because of the corruption. Anyone know the second ornate chest in the lab and the one in the manufacturing facility? :) I have already completed both of them and the related quests, so i just want to beeline to the chests.
