For the glass for measuring FO's and EO's you can use baby food jars, or any other small glass container you can clean out from previous use.
For lye, there are loads of things on the internet about accidents with glass after having used a while and the glass shattering. So, it does, in fact etch, when you see gang tags etched in glass, they used a lye concentration in a pen type thing. I also think it is good to replace your plastic container from time to time. And keep lye solution in the sink if inside.
Also wanted to remind everyone to wear eye protection. Goggles by all means, and I think BB has the best choice with the onion goggles as they have some padding around the eyes. I also purchased an inexpensive face shield on Amazon last week to go over that, as I found that goggles and paper face mask are not enough if the batter splashes. That's just me and being short and too close to the mixture.
I found that the big rubber gloves are best. The ones you get in the pharmacy are porous, water gets through, so soap gets through. If allergic to latex there are alternatives, again Amazon helped with that for chemical barrier gloves.
In addition, long sleeves. Amazon again has disposable lab coats (you don't have to throw it out after first use), since I don't have a man around to grab a used light weight long sleeve shirt from for summer, I got a lab coat to protect the arms from any soap getting on the arms when playing with tops or colors.
Just some thoughts.
