Thanks P. Emry for your loud shout for histo-literacy!
We need more like you!
As you know full well, there isn't a compound called xylol. That
execrable and meaningless word crept into histo-speak about 100
years ago, along with several other pseudo-chemical names of
organic solvents.
The correct designation is XYLENES (mixed isomers). This is a liquid
miscible with absolute alcohol and with melted paraffin wax. Xylenes
are also miscible with traditional resinous mounting media.
