One more thing:
"I never used a mask or anything,..."
A "mask" would do you no good - might as well not wear anything at all. You would need a respirator, but one that has the capacity of filtering out the potential fumes that you might encounter. Without knowing what all is in the ore, your best bet would be to make certain the wind is blowing solidly away from you and others (and NOT to your neighbor's house), or to just look at the purdy ore sittin' there on your desk.
We cannot stress to you enough how dangerous this can be. I'm not saying you're going to die, though that still "might" happen. (yes, it "can be" that dangerous) What I'm saying is, this should ONLY be done by persons who have taken the time to study and learn about what they're doing. When it comes to melting metal (including that within ores), that is a form of metallurgy. It's a science all on its own. When melting ores, there is also the chemistry involved. It's a lot of science.
I, personally, have no experience in that area. However, I have studied this and much other material, as well as having the benefit of being a veteran firefighter. Trying to smelt without proper knowledge, skills or equipment is literally taking your life in your own hands. If that doesn't matter to you, so be it - nothing we can do to stop you. Yet I wouldn't be able to sleep without knowing I had at least tried my best to warn you of VERY REAL dangers! Mercury fumes can kill quickly. Someone else said that Arsenic fumes can kill quickly, which also makes sense. Lead is dangerous. Toxic to breath fumes? Depends on your exposure. Lots of other unseen dangers as well. If you know what you're doing, it's relatively safe. Not knowing what you're doing, well, let's just say the Surgeon General doesn't even take the time to warn against the hazards of breathing such fumes, as it would probably be too late by the time you took it seriously.
"Do you know what kind of fumes I inhaled and how long I will be sick? Is it just a day or so cuz it's been about 4 days now and I wonder if I did perm damage "
That is very possible. With some chemicals, all it takes is a tiny whiff to kill a person. It may not happen immediately, but even worse, can be a slow and agonizing dead/illness.
Please, PLEASE use caution.
