About Volcanic ash
The Volcanic ash is a members-only item in Old School RuneScape.
"One of the ingredients for making ultra compost"
Over the last 30 days it traded between 149 and 210 gp on the Grand Exchange, averaging 182 gp. About 974,227 units changed hands per day. The price is down 4.0% 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 120 gp, which is 34.1% below the 30-day average price, so alching a bought one loses money.
