The facts on the card
The card carries these facts from its Wikipedia article.
- Blast refers to the combustion air being supplied above atmospheric pressure.
- In a blast furnace, fuel, ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward.
- The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Blast furnace article was read about 180,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 91: each hit it takes is cut by 36 %.
