# Custom Extras
#### Compressed Blocks
 \
\
We add Compressed Cobblestone, Gravel, and Sand for easier crushing with Ex Nihilo Sequentia\
\
\
\
Using a Hammer, these blocks can be crushed into the next form much more efficiently.
#### Leaded Iron
\
\
To make Leaded Iron, you must make the Compound first. Leaded Iron Compound is made by combining Raw Lead and Iron Ore in Ex Nihilo Sequentia Sea Water.\
\
Leaded Iron Compound is also used for other things, such as Immersive Engineering Kinetic Dynamos, and Thermal Series Grenades.
\
\
Leaded Iron Alloy is then made by combining Leaded Iron Compound and Coal in Sea Water again.\
This Alloy is used heavily in Immersive Engineering, as it's material is naturally very durable, and can be used as a nice alternative to Steel, also making it highly sought-after by Engineers, making it also very valuable. Be sure to sell it to Villagers when you have the chance!
#### Porcelain Bricks
\
\
**Porcelain Bricks** are made by Smelting Ex Nihilo Sequentia's **Porcelain Clay**, and used for making Immersive Engineering Coke Brick.\
\
\
\
**Porcelain Nether Bricks** are made by Alloying Porcelain Bricks and Nether Bricks in an Industrial Kiln, and used for making Immersive Engineering **Blast Brick**, Botania **Rune of Fire**, and Ars Nouveau **Glyph of Dampen**. Engineers make these as a way to "pad up" crude machinery, as it's pretty difficult to keep much heat inside without it's special heat-blocking properties.
#### Cooked Apple
\
\
Cooked Apples are an amazing food source for the early game. When eaten, they supply 4 full Hunger bars (8 Hunger), and 8 Saturation bars (16 Saturation). Made by either Smelting or Smoking **Apples**.
#### Fluoridian
\
\
Fluoridian Crystals are made by Infusing **Refined Obsidian** with **Fluorite**. Because of the high density of Refined Obsidian, the Fluorite's durability grows vastly, and is used all over the world for extremely dense gasses. The Crystals are used for making Mekanism's **Chemical Crystallizer**, and **Fluoridelyne Gas**.
