An indicating paper that is sensitive to ammonia and other alkaline materials. Zellner's paper is prepared in two steps. First it is dyed black with a substantive dye. Second it is soaked in a solution of soluble fluorescein (see fluorescein sodium). The dried strips detect alkalis and ammonia at the part per million level.
