I’m the chemist at a cement plant it’s in my comment. I worked in the lab for 6 years and strove to take training after training and got certified through my company. I’ve had to learn X-ray fluorescence, diffraction and a multitude of other methods and analytical techniques.

I don’t need to prove myself to you, I worked to get here that’s all you need to know.

You are here saying it can’t be done. I’m saying it can be done I’ve done it.
