In a Polish plaster factory, rubies and sapphires are created by an unknown and undesirable process!
In the calcination furnace of one of Poland's plaster factories, by the corrosion of refractory lining of kiln emerges corundum - ruby and sapphires
of different colours as well as dark blue. The process of their formation has not been satisfactorily explained and is undesirable because it disrupts
the furnace lining...Is it possible that something similar is happening elsewhere in the world in the same or similar type of furnace...Has anyone
experienced this? I'm sending a link to the article, Unfortunately, it's only in the Polish language, and I don't know that language well enough to
translate it into English...But there are some pictures and expert information!

I just looked at this on Google and it translates it to english quite well.
Very interesting article. It seems like ruby was formed but in there analysis
it only says corundum formed al2o3 with no mention of Chrome or cobalt
anywhere. Maybe that's an issue with there equipment sensitivity or the type of analysis they did. I don't know but definitely looks like synthetic
ruby stuff.
Either way it was a good read

I've read that high-content refractory bricks of Al2O3 are often joined by Cr2O3 to improve their properties! Chamotte/andalusite, in turn, contains
Ti and Fe oxides of natural origin. The blue colour of those Polish sapphires is certainly not caused by cobalt oxides, but the Fe and Ti oxides
contained in chamotte and andalusite refractory materials as a natural ingredient. The best translator I know was developed in the Czech Republic, at
Charles University, in Prague is based on neuron networks and artificial intelligence. It's free for non-commercial use, here's the link:
