Review on 🔘 G25 Stainless Steel Bearings, 1-inch Balls by Alfredo Nosrac

I ordered 10 of these stainless steel balls specifically for use as weights when cooking in an immersion convection oven (sous vide). When they arrived I was excited. I used to have to put spoons and butter knives in bags during the cooking process, which was difficult to remove and I was afraid the bag might break. When they arrived I washed them in hot water and dish soap. , then soaked for 30 minutes and rinsed. They have kept their immaculate shine as you can see from the photos. The recipe I made was for carrots: 1 pound carrots with salt, butter and sugar, cooked at 190 degrees Fahrenheit for 1.5 hours. As the timer ticked off, I took out the bag and noticed a strange discoloration on the balls. They were no longer shiny and reflective. Dark spots appeared on them and they became dull in luster. I also felt that the normally yellow, oily liquid in the bag had turned a gray tint. Was it metal parts of the coating that dissolved in the liquid? They had to be food safe. I was cheated on? I decided to experiment, partly to see if my carrots were actually still edible. I decided to make 4 different "scripts" and boil the balls in 190 degree water for 1.5 hours to see the result. I heated 2 new (shiny) balls in water to see if the water changes color and if the flakes are visible. I also decided to heat 2 of the ones already used to see if they would continue to stain the water. I heated 1 new sphere under vacuum with no water to observe the effect. Finally, I heated 2 in a salt and vinegar solution to somewhat mimic an existing food environment. Do acids and abrasives affect the coating? my insights? Look at the photos. Also, the bullets previously used for cooking that severely discolored the liquid would further discolor the water when reused. Acid and abrasives (like salt) seemed to make matters worse, but even ordinary water turned discolored. Considering the price, I am incredibly disappointed with this product. Especially when the manufacturer claims they are food safe. Do not order if you plan to come into contact with food.
