which ore types give xp when put into a furnace - ic2 experimental 2.1

i cant seem to find any info on which types of ores( crushed,purified, dust etc) give xp and which do not.

ive tried shoving all the ore types into furnaces on creative,including vanilla, but i didnt get xp for any of them. so that's why im asking.

you get xp for smelting vanilla ores in a furnace, but what about all the ic2 ores?
