I was going to introduce this on Thursday, but decided that may be too late in the week, so I will do it on Wednesdays.
I would like to introduce the Pottery Knowledge Quiz of the Week. This will be a four to five question quiz of general knowledge. Most of the questions can be answered probably off the top of your head, but then again maybe not. I have an extensive library, and will use a different book each week to help me with questions, and make certain I am technically correct. I will list the book that I use for the week so that if you want to find the answers, you can use the text. I will not use questions already written anywhere, but will dig into the material for questions. Hope this goes over well,
