[Histonet] paraffin problem

From:Inga Hansson

Hi everyone,

Has anyone experienced a difference in the quality of paraffin from 
different suppliers? Since we use rather small amounts, I found a 
company selling it in 1 kg packages. I noticed lately that it seems 
to be more opaque than before and although the melting-point is said 
to be the same it seems to take longer time to melt. Perhaps Im 
imagining it but there has been occasional problems in sectioning as 
well.
Comments?

Thanks ever so much!

Inga
