This Thermometer is 11″ tall by 6″ wide. The article is finished with a satin poly (polyurathane). The Thermometer is constructed from Birch, but will also be crafted in Oak or Walnut. The Galileo Thermometer is amazingly accurate. The cylinder comprises water and calibrated liquid filled spheres. The lowest floating sphere within the upper part of the tube indicates the approximate current temperature. I stand in the back of no matter what I make, so if for any reason you aren’t satisfied with my product please contact me so we will be able to make it right.
