This mod expands the ceramic industry, allowing your dwarves to access more sources of clay, make more items out of ceramics, and use more materials for glazing with a wide variety of colours, depending on what resources are available at the embark.

Note: This mod will mark several non-economic stones as economic, so make sure to check your Stones standing orders if you're wondering why certain stones aren't getting used.

If you're looking for the Steam version it can be found here! or on Steam Workshop!

Glazes

Glazes are made using the Pottery skill at a Kiln, though the process doesn't require fuel in most cases, producing them in stacks of four bars per job. These glaze bars can then be used in the normal glazing jobs. Glaze bars are stored in Bar/Block stockpiles under Metal bars, except ash bars which remain in Other.

The primary three glaze types are Ash, Lead, and Salt, each of which can produce different colours when mixed with various minerals. Ash is just regular wood ash, lead glaze is made using galena (not lead metal), and salt glaze is made using rock salt. There is also Bismuth glaze (using bismuthite), and Bone Ash glaze which is the only one that requires fuel to produce, since you need to calcinate animal bones. More information on the glaze components can be found in the readme.txt file.

By whatever means, dwarves have a chance to recover some silver when making galena-containing glazes. They're dwarves.

No guarantee that the colours of these glazes aren't completely ridiculous. Holy cow glaze chemistry is complicated. I haven't touched oxidation/reduction firing yet, either. Don't judge me.

More Ceramic Items

More objects can be made out of ceramics: beds, coffins, display cases, flasks, mugs, pedestals, slabs, table, and thrones. Each makes one item per clay boulder, except mugs which are produced in sets of three.

Bone Porcelain

A new type of ceramic can be produced, a translucent bone porcelain (aka "bone china") that is slightly more valuable than regular porcelain. This uses a clay that must be manufactured at a kiln using bone ash, fire clay or kaolinite, and microcline or orthoclase rock. The resulting bone porcelain clay can then be used as normal.

Clay Refining

Marginal clay soils (sandy clay loam and silty clay loam) can now be gathered using the "Collect clay" job at a Kiln. These can't actually be used for ceramics until they are refined^*, again at a Kiln using the Pottery skill, converting them into sandy or silty clay.

^* One slight issue, unrefined marginal clays can be used in "Make instrument/instrument part" jobs, and will consume resources, but won't result in an item. So if you're making instrument parts, keep that kiln well away from your unrefined clay stockpile, or better yet, refine all your clay first.

INSTALLATION

Please see the included readme.txt file for installation instructions.

This mod replaces the following default raws:
   

• entity_default.txt
• inorganic_other.txt
• inorganic_stone_mineral.txt
• inorganic_stone_soil.txt
• reaction_other.txt

   
WARNING! THIS MOD CHANGES HOW THE GAME HANDLES CLAY AS A RAW MATERIAL!
   
This mod may break any other custom reactions that refer to MATERIAL_REACTION_PRODUCT:FIRED_MAT (ie. anything that uses clay).
If issues occur with other custom reactions, replace all their references to FIRED_MAT with CR_KILN_MAT.


Changelog:

• v 1.04 Prevented glaze materials being used as base for artifacts produced during worldgen.
• v 1.03 Bone porcelain clay can now also use fire clay in place of kaolinite, and microcline in place of orthoclase (thanks Evaris!). It also now requires two bars of bone ash.
• v 1.02 Added descriptions for each reaction listing its requirements; changed glaze making jobs to use GLAZING skill.
• v 1.01 I forgot the pedestals. Added pedestals.
• v 1.0 Initial release.
