Interesting. From what I've read you need to get temps up to at least 300 Degrees F. to completely dissolve some ambers and others up to 500F. (per the blog post posted by mthompson) So I am curious to see how you do this and even more curious to hear how it turns out. Best of luck with this.
"Sometimes when I reflect back on all the beer I drink I feel ashamed. Then I look into the glass and think about the workers in the brewery and all of their hopes and dreams. If I didn't drink this beer, they might be out of work and their dreams would be shattered. Then I say to myself, it is better that I drink this beer and let their dreams come true than be selfish and worry about my liver." --Jack Handey
