Buy RS3 Lantern lens
The Lantern lens is a round disc of glass in RuneScape 3. Players make it with the Crafting skill at level 49 by using a glassblowing pipe on molten glass. Making one gives 55 Crafting experience.
A Lantern lens has many uses. Combine it with a steel frame or a Bullseye lantern frame to make a Bullseye lantern. It is also used to make a Sapphire lantern, with or without oil. You can mix it with Pink dye to create a Rose-tinted lens.
The lens is tradeable and noteable, so it is easy to buy, sell, and store. It cannot be equipped or stacked. It is very light at 0.028 kg.
The Lantern lens can also be disassembled for Invention. It gives 1.4 disassembly XP and produces 2 materials. Possible materials are Clear parts, Delicate parts, Smooth parts, and rare Enhancing components. The base junk chance is 46.1%.
Pick up a Lantern lens to skip the glassblowing and get straight to making lanterns or gathering Invention parts.
