Narrative:

During climb out from den at approximately 12000 ft, I noticed the upper right corner of my (captain's side) forward windshield glowing and appeared to be delaminating. I asked the first officer to turn off my windshield heat. The glow immediately stopped and approximately 10 seconds later my windshield cracked. We informed departure control of our intentions to return to den without declaring an emergency as we observed no indications of any emergency. We then informed our flight attendants that we would be returning to den with a cracked windshield. We asked departure control for delay vectors to allow us enough time to complete the appropriate checklist. We then completed an ILS approach to runway 35L at den and the rest of the flight was uneventful. Upon arrival at the gate, the postflt inspection revealed several burn marks extending from the upper right corner of the windshield back along the upper part of the fuselage. I then made an appropriate logbook entry and informed maintenance control.
