Hi Laurie,
	My 95-96 copy of the Alfa-Aesar-Johnson Matthey catalog refers the
reader looking for sodium polytunstate to Sodium Metatungstate (powder
form).  The catalog lists only the 50g - $35.70 and 250g - $107.00
quantities.
	Geoliquids Inc. , 15 E. Palatine Rd. Suite 109, Prospect Heights,
Ill 60070, 1-800-827-2411, lists Sodium Polytungstate.
	In liquid form,
		in 1-25 Pound lots -- $95.00/lb.
		25-99  "       "       --$90.00/lb
		100 Pound Lots  -- $87.00/lb
	These are available in 1 lb, 5 lb, or 100lb containers.

	In Powder Form,
		in 1-25 Pound lots -- $98.00/lb.
		25-99  "       "       --$94.00/lb
		100 Pound Lots  -- $90.00/lb
	These are available in 1 lb, 5 lb, or 100lb containers.

They also sell Tugngsten Carbide Powder (1 micron) as an additive for the
Sodium Polytungstae to make it heavier that its nominal Density of 2.9.
Price is $35.00/lb in 1 to 100 pound lots.

Cheers
Mike
