Glass Making Guide

To make glass you need Soda ash from either Seaweed or Thick kelp, and Sand from one of the two sandmines. When used together in a furnace it will make Molten glass which can be shaped into various glass objects. This is a guide detailing the entire process of glass making starting with harvesting either Seaweed or Thick kelp.
==Harvesting Seaweed==
===Beginner Method===
*Level Requirements: 22 Gathering
Seaweed can be found on the ground along the coast of Immerbury and along the coast south of the Ancient Coast. It requires level 22 gathering to pick up but this is the only requirement. This is great for new players starting out who don't have a ship yet and don't have the quests Ship Together or Imperial Quartz completed. The downside is that the player has to wait for the Seaweed to respawn to get more and it is much slower than harvesting Seaweed plants underwater. 
===Underwater Seaweed Plant Harvesting Method===
*Quest requirements: Ship Together (to make a ship), Imperial Quartz (for Bottles of air)
*Level Requirements: 35 Gathering, 30 Carpentry
*Item Requirements: Breathing device, Insulating gloves, Bottles of air, Shears
*Recommended Items: Blue Froghide or Oceanic armor for Water typing
*Recommended: 51 Carpentry for a Cargo ship
Once you have a ship, you can travel a spot in the ocean near Al Aljar where you can dive underwater and harvest Seaweed from Seaweed plants which requires level 35 Gathering to harvest, which you harvest with Shears. You will need a Breathing device and Insulating gloves from the Slayer master North-west of Immerbury. The breathing device allows you to breath underwater as long as you have Bottles of air which can be acquired after completing the Imperial Quartz quest. The insulating gloves prevent you from becoming paralyzed from the Eels underwater. It is recommended that you wear Water typed armor both for the typing and for the armor which protects you against the Eels. Underwater if you go straight there is a cave entrance to another area which has more Seaweed plants. To the left however is a cave going to Idrogatrs, which you want to avoid. You do not need too many Bottles of air, just a few, 5 if you want to play it safe. A Cargo ship can be handy to have as it carries 30 extra inventory slots on the ship for carrying Seaweed. 
======Banking to Al Aljar======
If you have a Toragua, you can use it as a secondary ship so you can have your ship on one side of the island near the whirlpool where the Air altar is, ride your paid horse (if you have one) from one side of the island to the other and then ride your Toragua to the bank going back and forth. 
If you have a ground mount with a handcart and a flying mount you can ride your ground mount to the other side of the island with the handcart full of seaweed and then bring out your flying mount and fly the rest of the way from the island to the bank in Al Aljar and back. 
Otherwise, you can just sail from the Underwater area location to the Al Aljar bank with your ship. 
===Seaweed Farming Method===
*Quest requirements: Ship Together, Imperial Quartz
*Level Requirements: 30 Carpentry (to make a ship), 33 Farming (for farming Seaweed), 42 Magic (for Sprout spell)
*Item Requirements: Breathing device, Bottles of air, Seaweed spores, Spirit runes, Water runes, Earth runes, Shears, a Trowel
*Recommended: Earth staves
The farming method of harvesting Seaweed is not recommended, as farming Kelp is much more efficient for the amount of resources used, however do farm Thick kelp requires 44 Farming while farming Seaweed requires only 33 Farming. Nonetheless the method is posted as an option. You will need Seaweed spores for farming Seaweed which can be made by putting Seaweed into Buckets of water and then waiting for the Seaweed to germinate. Once germinated click "empty" on the buckets to get spores. To farm Seaweed you need to travel to Kilwe where there are 2 spots you can farm underwater. The first spot is right by the bank in Kilwe Village which has 4 underwater farming plots and requires a boat to get to, and the other is further away on the island to the east of Kilwe village, however it does not require a boat to get to and has 8 underwater farming plots. Farming Seaweed requires Seaweed spores, a Breathing device, Bottles of air, Shears, and a Trowel. You do not have to worry about Eels underwater when farming. To make this method viable, you will need to use the Sprout magic spell which requires level 42 Magic, 1 Spirit rune, 4 Earth runes (2 if using an Earth staves), and 2 water runes per cast. Each plant needs 2 casts of the spell in order to instant be ready for harvest. It is recommended to use Earth staves for this method as it will cost only half of the Earth runes. 
===Thick Kelp Farming Method (Recommended if farming)===
*Quest Requirements: Ship Together, Imperial Quartz
*Level Requirements: 30 Carpentry (to make a ship), 42 Magic (for Sprout spell), 44 Farming (For farming Kelp)
*Item Requirements: Breathing device, Bottles of air, Thick kelp spores, Spirit runes, Water runes, Earth runes, Shears, a trowel
*Recommended: Earth staves
Farming Thick kelp is the most efficient way to get Soda ash if the player has the requirements. The Soda ash output of Thick kelp is very large. There is one Thick kelp spawn in the game on the southern tip of the Ancient Coast in which a player can put in a Bucket of water and wait to germinate into Thick kelp spores just like Seaweed spores. When they are germinated, the player can empty out the buckets to get Thick kelp spores to grow Thick kelp. The process of germinating Thick kelp should continue until the player has an adequate enough amount of Thick kelp spores that they want to farm with. One Thick kelp can turn into 8 spores. The method for Thick kelp farming is exactly the same as farming Seaweed as posted above. 
==Making Soda Ash==
*Recommended: Ring of seas (for increased chance of double Soda ash)
When you have a good amount of Seaweed or Thick kelp you can cook on on a fire or range to make Soda ash. The amount of Soda ash that you get is not equal to the amount of Seaweed or Thick kelp that you cook. There is a percentage of a chance to get double Soda ash which increases with your Crafting level. If you are wearing a Ring of seas while making Soda ash, the chance increases more. Cooking Kelp will give you double the output of Soda ash than Seaweed, giving an additional bonus.
Example: At level 64 crafting you have around a base of 43% chance of double Soda ash per Seaweed, but with Ring of seas on you have around a 63% chance of double Soda ash. With Thick kelp instead of Seaweed this would be much higher. 
==Gathering Buckets of Sand==
===Al Aljar Mine===
*Quest Requirements: The Lost Quarter
*Level Requirements: 10 Thieving
*Item Requirements: Rope, Buckets
After the completion of The Lost Quarter quest, you gain access to a sand mine in Al Aljar which is underneath the sandbox. It requires a rope to enter, however you get your rope back when you come back up. It is recommended that you steal quite a few buckets from the buckets stalls in Al Aljar so that you can easily fill them up with sand. Once you have collect sand into buckets, you can empty them and get 2 Sand per Bucket of sand which is used just as a Bucket of sand when making Molten glass, but if you empty the buckets you get double, as the Sand or the piles of pure sand is equivalent to Buckets of sand. 
===Gesterville Dungeon Mine===
*Requirements: 34 Firemaking, 1 Blasting tube, Buckets
Although the Al Aljar mine isn't too far from the bank, there is an alternate sandmine underneath the town of Gesterville that is closer to the bank, however it requires a Blasting tube to blast out the wall to get to it, which requires level 34 Firemaking to light. They take a long time to make and have a very long list of ingredients. There is another wall within the sandmine as well which can be blasted out with another blasting tube to get to the Earth altar, Mountain earth piles, and Guano piles. As stated above once you have Buckets of sand, if you empty them out you will get double the sand. 
==Making Molten Glass==
*Optional: Magma ring (for increased chance of double Molten glass)
Once you have an equal amount of Sand and Soda ash, you can make Molten glass by using both in a furnace together, the same furnaces used for smelting in the Smithing skill. Just like Soda ash, there is a percentage chance of getting double Molten glass which increases with your Crafting level. If you wear a Magma ring while making Molten glass, the percentage chance of double Molten glass increases, but not by a large amount. It is for this reason that the Magma ring here is listed as "optional". 
==Making Glass Items==
*Requirements: Glassblowing pipe
Now that all you have is Molten glass you can turn the Molten glass into glass with a Glassblowing pipe. It's good to take into consideration what glass items will be useful to you first, and then worry about what gives the most xp. Funnels do not consume the "Funnel plan" required to make them, however they are not as useful as having hundreds of Vials for instance due to potion making with the Heblore skill. Prisms can be useful for making elemental staves in bulk, Oil lamp glasses can be beneficial if you're interesting in making Oil lamps for light sources, or Lantern lens to make Lanterns which are a better light source.
