I have noticed this time and again on this website - after traversing many teks and posts.
If you want to make a professional sounding tek,
->It's NAPHTHA. Not NAPTHA.
Just saying, we would certainly get made fun of if we abbreviated hydrochloric acid as HCL, or used "clorine" or "sulferic acid". As I think people here put themselves a step above your standard "druggie", everyone here should want to sound like we actually know what we are talking about, and sound professional about it!
That is all

Have a good day gentle peeps.
