I found some nice pieces of driftwood in a creek. i know nothing about trees so by looking at them i have no idea what kind they are. so i was baking one of the large pieces to sterilize it, and it looks like some sort of sap is coming out of an area of it. is it some sort of pine? is it safe to put in a snakes tank? here are a couple photos. the part with sap is the underside of the top left corner in the first photo. i originally planned on breaking the piece in half for two different tanks. if i can't use the left half with the sap, can i still use the right half that doesn't have any sap coming out?
