Adamantite Ore can be much easier to locate than its counterpart Titanium Ore, due to the coloration. Whereas Adamantite has a distinctive red color, Titanium has a sparkling dark gray with minuscule spots of green and pink (when in clusters). The grayish color makes Titanium harder to spot, and in dark areas it might even be mistaken for other ores like Platinum, Silver or Lead ore – it is however very easily distinguishable from the Stone Blocks where Titanium possesses a much darker, almost tar-like texture.
The Minimap is not very helpful for locating Titanium Ore, since Lead Ore is marked with almost the same color on it.
The Spelunker Glowstick, Magic Lantern, and similar "treasure detectors" will flag Titanium Ore, but will not distinguish between it and the many other ores that are much more common. The Metal Detector and its upgrades can at least identify when Titanium Ore is nearby, but the best way to quickly spot the specific ore is to use a Spelunker Potion.
Before 1.4.1, in Journey Mode it was more cost effective to duplicate the ore rather than the bar as the ore takes 100 research and the bar takes 25, however it takes 5 ore to make one bar, therefore researching 25 bars used to require 125 ore.
It is beneficial to use Spelunker Potions and look for Titanium near the bottom of the world.
Titanium is a real metal. Its legendary reputation for durability is more based on its inert nature and corrosion resistance rather than its strength; in reality, titanium is no stronger than steel, though it is lighter and far more corrosion-resistant than steel.
