Ceramics is a mod designed to increase Minecraft's gameplay using clay. Originally inspired by the clay bucket from Iguana Tinker Tweaks, this mod simply added a clay bucket, but now it adds quite a few other features made from clay to both improve the early game and be used in long term builds.
In the mods current form, it adds features in three categories.
Clay buckets: Early game bucket alternative.
Can transport cold liquids with ease, but breaks after emptying a hot liquid like lava.
Unlike other clay bucket mods, these are fully dynamic and will automatically add variants for any mods that use the Forge universal bucket (such as Tinker Construct or Forestry).
Clay armor: Alternative to leather armor early game.
Leather is often hard to obtain before iron, so clay provides a more affordable alternative.
Apparently clay plate armor was once a thing, so kinda historically accurate.
Clay shears: An alternative to iron shears.
Similar to other clay tools, have less durability than the iron alternative.
Unlike the other clay tools, shears are actually faster and sharper than iron shears as clay is a sharper material.
