Superglass Make

Superglass Make turns all sets of the two ingredients for glass into Molten glass instantly and without the need of a furnace. A set consists of: Note: Kelp and Edible seaweed must be ashed first, Lunar magic will not combine raw kelp or edible seaweed with sand.
 * One Bucket of sand.
 * One of Soda ash, Seaweed, or Swamp weed.

Unlike when making molten glass normally, the buckets are not returned to the player after glass has been made - the entire bucket of sand and seaweed/swamp weed/soda ash are consumed to randomly produce either 1 or 2 pieces of molten glass. On average, each set will produce 1.30 pieces of molten glass whereas regular molten glass crafting will only produce 1.00 pieces. Please note that the spell only works on PAIRS of ingredients.

A maximum of 13 pairs of ingredients can be converted per spell. To do this, the player must wield an Staff of air (or equivalent staff that provides free air runes), while having in inventory the 13 sets of ingredients, the fire runes for the spell, and the astral runes for the spell. This will produce a long-term average of 16.9 pieces of molten glass per cast. Using this spell to create molten glass can simultaneously train the magic and crafting skills for significant profit.

Profit
Jagex has now updated Superglass make, and this method no long brings profit. this spell can only be cast once every 1 minute, much like the spell Charge

Maximising Speed
The use of mousekeys can nearly double the number of casts you can do in an hour. Your mousekey settings (assuming Windows Vista) should be set as follows: Your sand and seaweed should be on top of each other in your bank. Before starting, you also need to set the 'withdraw X' feature to be withdrawing 13 items. Assuming you have seaweed on the bottom of your stack, place your cursor over the seaweed and press 5,2,5,8,5,2,5. This should withdraw 13 seaweed and 13 buckets of sand. After you have cast the spell, deposit your molten glass with the 'deposit all' feature and repeat the process. Placing your stacks next to the deposit all button should further speed up your banking time.
 * Top Speed - 3 notches below maximum
 * Acceleration - 1 notches below maximum
 * You should also turn on sticky keys
 * You should also turn on one-button clicking

Using this method allows you to achieve up to 600 casts per hour, however for those new to mousekeys, 400 casts per hour is probaly more realistic.

Maximising experience
While making molten glass using superglass make gives less crafting experience per set of ingredients than when made in a furnace, it produces more pieces of molten glass. As such, Beer glasses, Candle lanterns and Oil lamps all give less experience when crafted via superglass make due to the small amount of experience gained in glassblowing, while all other crafted glass objects give more experience via superglass make,also gives crafting experience while casting spell.

As with all Lunar Magic spells, the Lunar Diplomacy quest must be completed to cast this spell.
