The problem I have with Clear-Rite is that one has no idea when the vapor
level is too high. Xylene may be health haz 2 and Clear-Rite is 1 but I feel
we're lured into a false sense of safety with Clear-Rite. What does too much
Clear -Rite smell like? NOTHING!

		Instead of working with Xylene , we substitute Clear-Rite.
I'm told 
		that Xylene clears more quickly so I am careful not to rush
the 
		times,but we get good results.  
		           The Clear-Rite  is a mixture of alphatic
hydrocarbons.  It 
		has a health hazard index of 1 ( slightly hazarous). I still
wear 
		gloves and use it in the fume hood. Xylene has a health
hazard 
		index of 2 ( moderate hazard).

		          The supplier , if your interested , is :
		                               Somagen Diagnostics Inc.
		                               Edmonton , Alberta
		                               Fax: 1-780-438-6595


		          The manufacturer is Richard-allan Scienific
		                                        Kalamazoo , MI
