Re: Preparing Al sheets; other factors
I asked to my chemicals supplier about waterglass; they have liquid form (something around 20-30%)... Is the addition of NaOH strictly necessary? Waterglass is already alkaline in solution. What's the purpose of adding NaOH? Another question is about beer; with "weak beer", do you mean "low alcohol content" or "clear/pale" (or both)?
