I'm also in my 50s, a chemical engineer among other things. When I was in my mid-teens, I could easily get a lot of chemical stuff OTC from the local
pharmacy, or in some cases groceries, hardware stores, and farm and garden supply shops, e.g. hydrochloric acid, sulfuric acid, nitric acid, potassium
bromide and iodide, chloride of lime, sulfur, potassium nitrate, ammonium nitrate, sodium carbonate, copper sulfate, potassium permanganate, zinc
carbonate. Some are now more difficult to get. Glassware was also relatively a lot cheaper. |
