About Soda ash
The Soda ash is a members-only item in Old School RuneScape.
"One of the ingredients for making glass"
Over the last 30 days it traded between 19 and 45 gp on the Grand Exchange, averaging 28 gp. About 27,863 units changed hands per day. The price is up 114.3% across that window. The Grand Exchange buy limit is 13,000 every 4 hours.
Casting High Level Alchemy returns 1 gp, which is 96.4% below the 30-day average price, so alching a bought one loses money.
