Each Hot Liquid Lure is a unique and one-of-a-kind piece of colored glass. Hot Liquid Lures can be made with any color in the spectrum, and sizes range from small 2-ounce heads to double-extra-large 4-ounce heads. Dichroic glass contains multiple micro-layers of metal oxides, which give the glass dual-color optical properties. Plus, there are more than 45 different colors of dichroic coatings. Available styles include pusher, popping and bullet heads.
