For the first time, you can switch your from one world to one of the officially Blast Furnace worlds. If you're less than level 60 make sure to RuneScape Gold bring some gold coins since you'll have to pay Blast Furnace Foreman every now and then to time. Also, you will require stamina potions as you will get exhausted after just a few minutes. This method can provide amazing experience rates especially on lower smithing levels, but it is extremely expensive. The process of leveling from 40 to 99 takes about 65mil (after selling the bars).
LEVELS between 74 and 99 ADAMANT TIPS. An alternative as compared to Blast Furnace, which is quite expensive is crafting adamant dart tips using adamantite bars. Level 74 is necessary to make those with some profit. This is not the only reason to use this method as the method of making dart tips is extremely AFK friendly. While doing this method you can expect to make around 60k per hour which is a decent amount. If you decide to go this route keep in mind that you must finish your Tourist Trap quest beforehand which instructs you on how to make darts.
LEVELS 35 99 CANNONBALLS. This is one of the oldest and most known methods of making money that involves Smithing skills. To do this one you need to finish Dwarf Cannon Quest and bring Steel bars, which are necessary to create Cannonballs. The process should earn the player around 10k exp an hour and more than 100k gold. Although it's a decent money-maker for beginners, there are better ones later on , so be sure you change to higher compensated ones. Also, slow experience gains are not worth it.
LEVELS 54+ MITHRIL DART Tips. If you've already completed done the Tourist Trap quest completed you can begin to make Mithril tips from Mithril Bars at level 54. Though this method will yield lower returns than cannonballs however it gives you better rates of experience. Most important is that you can semi AFK in the process of creating Mithril Dart Tips so it is a great thing to perform while you do other things on your computer.
LEVELS 15+ BLAST FURNACE. Although previously there was Blast Furnace before this guide , this method uses different kinds of ores, other than gold. Through the use of other kinds of ores , the player will not receive the bonus of Goldsmith Gauntlets but it is worth noting that different types of ores are thanks to that OSRS Money fact significantly more profitable.
