The Magnifying Glass can be used to start fires, much like a firestarter, though more quickly and without consuming durability.
However, this efficiency comes with the tradeoff that the Magnifying Glass can only be used when you have access to sunlight.
This means that when using it, either you
or the block you are attempting to light must be able to see the sky. Magnifying Glasses can also only be used during the day and in clear weather.
Magnifying Glasses can also be used to light Firepits, Pit Kilns, Torches, and anything else that a Firestarter can light.
Tier II
To make a Magnifying Glass, begin by forging a Magnifying Glass Frame from a rod of your chosen material. Magnifying Glasses can be made from a variety of materials including:
Bismuth
Brass
Gold
Rose Gold
Silver
Sterling Silver
Tin
Then, craft the frame together with a Lens to create your Magnifying Glass.
If you would like to salvage the Lens and/or metal used to make a Magnifying Glass, you can remove the lens from a frame by placing the Magnifying Glass into your crafting grid.

Magnifying Glasses are also needed to cut Gems. This does not consume the Magnifying Glass.
