Thanks KandleKrazy. That Hansel and Gretel whupped my butt! Using the heat gun on the glass didn't work, it came right back. Since these were for a friend I had to make them over, and that fo did not want to mix in. I had to raise the temp, mix, raise the temp, mix, until it all worked in. I may be searching for a new gingerbread scent soon.................
