I like learning new things, especially about things used in industry. I have blogged about a few items that I have learned about, but on item I have come across that I found interesting was a ceramic tube. Did you know that ceramic tube can be used for insulations? They are gas tight and can withstand high temperature. You can see them used in the electric industry. Have you ever noticed those white looking things on electric wires, yep those are a type of ceramic tube. They insulate and protect the electrical wiring. Can you think of other uses for ceramic tubes? How about their use in furnaces can kilns? I learned something new today. How about you?
