[Histonet] Lithium carbonate

Any chance it should have been 0.5 g lithium carbonate in 500 mL water? 
Maybe someone typed the label wrong? That's happened to us before. Is it 
supposed to be a 1.0% solution, or a 0.1% solution?

Only reason I'm asking is that the only place we use lithium carbonate is in 
the LFB stain for myelin, and we use a 0.05% solution (0.25 g in 500 mL).

If you are adding 5 g to 500 mL of water, that's a 1% solution, which, for 
lithium carbonate, is very close to being a saturated solution (where not 
all of it will dissolve).

Good Morning-
Making up some lithium carbonate - it is staying very milky in appearance - 
have not previously had that happen.  We tried a couple different times - 
same result.  We are not doing anything different - 5g lithium carbonate to 
500ml Type I water.
Any thoughts?
Thanks, Nancy
