About Pyrophosphite
The Pyrophosphite is a members-only item in Old School RuneScape.
"A phosphate rich mineral dust"
Over the last 30 days it traded between 86 and 398 gp on the Grand Exchange, averaging 153 gp. About 6,455 units changed hands per day. The price is down 67.3% across that window. The Grand Exchange buy limit is 13,000 every 4 hours. Selling one at the average price costs 3 gp in Grand Exchange tax.
Casting High Level Alchemy returns 18 gp, which is 88.2% below the 30-day average price, so alching a bought one loses money.
