I agree 100% Donald, even the weak solutions sold in hobby shops can be very dangerous, I know, we experimented with it! anyone that chooses to use acid to make ground glass, must take the proper precautions as it will cause very serious burns as you have stated.....I was not trying to suggest that anyone use acid, without taking the proper precautions for their health and well being, I am sorry if it came across that way, thanks for bringing this very important point up.
