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 I´m 
imagining it but there has been occasional problems in sectioning as 
well.
Comments?

Thanks ever so much!

Inga
