Crude glycerin does not solidify at room temperature. It's the soaps combined with the glycerin that give cause for any type of solidification. I suppose that technically glycerin with a higher solidified soap fraction, such as waste oils from animal fats, is indeed "crude." But in such cases the soap volume is generally higher than the glycerin volume, which would mean that calling it crude glycerin would be incorrect. Technically it should be named after its greatest fraction - soap.
When attempting to find a buyer for the glycerin, most won't accept it until the soap stock has been removed. They can contend with the water, alcohol and general discoloration. But they cannot as a general rule contend with crude soap "contaminated" with glycerin.
