Potassium bichrmate crystal

[Winslow]

Neil Ellis waxes lyrical about the colour this gives on cedar and Kalantas timber, I want to try it out. Tried all normal sources and met with blank stares. Anyone know where these crystals can be obtained in or around Sydney, preferably North Shore?

Try the Yellow pages under Chemical Suppliers or Dyes or try the older established chemist shops. Occasionally they have a tin of it out the back. High school science labs usually have some they are happy to share. Try also Tannery or tannery supplies.

Even the police might have some kicking around somewhere as it was used as a reagent for breath testing years ago.

However, maybe the first place to try might be the one who's MSDS is in the post above.

Hope this helps.
