Editing Limestone (section)

=== Scarcity ===
Limestone is a major industrial raw material that is in constant demand. This raw material has been essential in the [[iron]] and [[steel]] industry since the nineteenth century.<ref name="Haumann-2020">{{cite journal | title=Critical and scarce: the remarkable career of limestone 1850–1914 | last=Haumann | first=S. | journal=European Review of History: Revue européenne d'histoire | year=2020 | volume=27 | issue=3 | pages=273–293 | doi=10.1080/13507486.2020.1737651| s2cid=221052279 }}</ref> Companies have never had a shortage of limestone; however, it has become a concern as the demand continues to increase<ref name="SparenbergHeymann">{{cite journal | title=Introduction: resource challenges and constructions of scarcity in the nineteenth and twentieth centuries | last1=Sparenberg | first1=O. | last2=Heymann | first2=M. | journal=European Review of History: Revue européenne d'histoire | year=2020 | volume=27 | issue=3 | pages=243–252 | doi=10.1080/13507486.2020.1737653| s2cid=221055042 | doi-access=free }}</ref> and it remains in high demand today.<ref name="ResearchAndMarkets">{{cite web | url=https://www.businesswire.com/news/home/20200609005311/en/Global-Limestone-Market-Analysis-and-Forecasts-2020-2027---Steady-Growth-Projected-over-the-Next-Few-Years---ResearchAndMarkets.com | title=Global Limestone Market Analysis and Forecasts 2020-2027 - Steady Growth Projected over the Next Few Years - ResearchAndMarkets.com | publisher=businesswire.com | work=Limestone - Global Market Trajectory & Analytics | date=9 June 2020 | access-date=24 March 2021 | author=ResearchAndMarkets.com}}</ref> The major potential threats to supply in the nineteenth century were regional availability and accessibility.<ref name="Haumann-2020" /> The two main accessibility issues were transportation and property rights.

Limestone was classified as a critical raw material, and with the potential risk of shortages, it drove industries to find new alternative materials and technological systems. This allowed limestone to no longer be classified as critical as replacement substances increased in production; [[Minette (ore)|minette ore]] is a common substitute, for example.<ref name="Haumann-2020" />
