So as we all know this game starts to slow after you start to get into it, and for one flawed reason, organic Flux. Firstly I'd like to propose the thought: If your flux is made from herbs, why doesn't it just burn up in the steel making process? Have you ever heard of a mortar made of herb material? I sure haven't, so let's look for an alternative!

If we look back at history we can come up with one material to replace these both, Limestone. Limestone is one of the oldest flux materials used for both smelting AND making mortar. In the smelting process a powdered Lime was added to the contents of a smelting furnace to remove impurities, this same lime is also used in forging steel tools to further remove impurities. The Romans also used a Lime mortar, made of Lime, sand and water, in the process of making the most famous concrete in history. So why don't we use it?

The process of making Lime that is ready for smelting is a bit more in depth than mining and using. To prepare Limestone for its beneficial use you first have to crush it into small chunks or a coarse powder. Secondly the limestone is heated in a kiln at 500 degrees, this process creates quicklime, interestingly enough quicklime may have been used for Greek fire. This lime is then crushed again and water is added to the mix it make hydrated lime, or what is known as Slaked Lime.

This Lime is a much better proposed material for the use of flux but won't replace herbalism for its great use for potions, naptha and flavours. This should ease the more random process of gaining flux into a less random but equally laborious task for all of us. This addition of Limestone also gives us the option for another building material other than granite and marble as well!

tl;dr Limestone is better, please add this
