The most majior change in natural resources was the switch of main wood to more metalic substances. It actuall started a little before the industial revlution with the invention of coal reverberatory furnaces known as cupolas. Cupolas brought iron ore into the familiar iron matalic substance. This new method made it so impurities like sulfur do not get stuck in the metals.
The Next important invention was by Abraham Darby, who invented funaces that were powered by coke. This was some time around 1709. It was although mainly used for practical hand made things like pots, kettles, ect. Eventually coke iron was cheaper and comsumed more than charcole iron which is important in the industial revolution because it was the metalic age, and the more, cheaper metal, the better.
In the 1780's the increase in the British iron ore and iron industry started. This is mostly accreded to a new way of making iron. This new way was not held back, like the old way was, by carcole supplies, which werent that plentiful in Britian.
Now, because of the new way of making iron, Britain actually started exporting their iron bars to other countries instaid of importing it from countries like Sweeden and Russia.
Also and inprovement in the making of steel was just invented about 40 years earlier byBenjamin Huntsman, who developed his crucible steel technique. For this he mainly used blister steel, which was made by the cementation process.
These two discoveries in raw materials had great inpact on the industial revolution. It made steel and iron cheap, the two most needed raw materials for this industial revoltuion. These materials were used in everything from railroads to factories to anything you think of when you think industial revolution.
