The Superglass Make lunar spell can instantly turn an inventory full of sand and seaweed into molten glass. On average, it will make 1.3 glass for every sand-seaweed pair, and without using mouse keys, one can cast it about 360 times an hour. Using mouse keys, the number of casts per hour may rise to up to 500. Withdraw 13 sand and 13 seaweed, close the bank, activate the spell, and wait for the animation to finish before banking the resulting glass and repeating. Alternatively withdraw 18 sand and 3 giant seaweed, close the bank, activate the spell, and wait for the animation to finish before banking the resulting glass and repeating. For best rates withdraw exact runes and ignore dropped glass, this will still get 1.45 extra molten glass per cast as giant seaweed has increased bonus rates.
