It is possible to use flower petals and other organic matter as "inclusions" in fused glass. This paragraph below originally posted on the Warm Glass website explains:http://www.warmglass.com/

"Items as diverse as leaves, twigs, and cellophane wrappers, can also be used as inclusions by sandwiching them between layers of glass and using them to add unusual effects and textures to glass pieces. These inclusions will often carbonize from the heat of the kiln, sometimes leaving a fascinating "ghost image" (also called a "heat signature") behind. For fusers with money to burn, try sandwiching a US dollar bill between two pieces of float glass and heating to 1500 degrees F. The result may surprise you." 

Gil Renolds' article provides some kiln instructions:

I've attached a bibliography of books, articles and websites that address inclusions.
