We investigate dust production and stellar mass loss in the Galactic globular cluster NGC 362. ... We detect several cluster members near the tip of the red giant branch (RGB) that exhibit infrared excesses indicative of circumstellar dust and find that dust is not present in measurable quantities in stars below the tip of the RGB. ... The two most extreme stars, variables V2 and V16, contribute up to 45% of the total cluster dust-traced mass loss. ...
