I have 340g in a packet to give away. Originally purchased in 1979 from "Advanced Canada" for photo emulsion silk-screen printing. Info about this chemical: https://portal.cjchemicals.net/store/cj-chemicals/product/ammonium-bichromate
If doing an internet search, note that results may return for ammonium dichromate instead of ammonium bichromate.
