Unwrap ham from all of the packaging. Place the ham into a deep 8-quart slow cooker. If your slow cooker isn't deep or wide enough, you won't be able to put the lid on.
Whisk together the sweet tea and brown sugar into a small sauce pan.
Whisk together well then pour half of this mixture on top of the ham, setting aside the rest of the liquid for later. Drop 5 of the cloves into the bottom of the slow cooker along with a stick of cinnamon. Place lid on crock pot and cook on low for 4-6 hours.
About 20 minutes before serving the ham, boil the rest of the liquid you set aside earlier. Drop in the last 5 cloves and remaining cinnamon stick. Whisk it well. Reduce heat to medium low and glaze is bubbly and thickened (about 15 minutes) stirring occasionally.
Once thickened, remove cinnamon sticks and cloves from the glaze. Then pour glaze over ham or use a basting brush to gently brush it all over the cooked ham.
