First attempt at alkali metal thermometer tonight!
So in principal I now have everything I need to make a liquid alkali metal thermometer. propane-oxygen torch didynium specs argon supply some possibly suitable capillary tubing ....some sodium potassium alloy. First attempt will be made using sodium/potassium alloy, simply because it's easier to handle. Hopefully I will be able to show you how it succeeds, or crashes and burns!
