Try buying tungsten disulfide as "dry lube", some hardware stores have it, but lots of people sell it on eBay rather cheaply. This is then heated to 1250°C in a crucible with a propane torch until the dark green powder has turned canary yellow. This is WO3 which can be dissolved in sodium hydroxide to yield Na2WO4.

EDIT: Fixed incorrect chemical formula

Thanks for the tip! I will definitely have to check my local hardware store for some.
