Galileo's Liquid and Glass Thermometers

NO LONGER AVAILABLE!

They are also called "Termometro Lentos"  
which is Italian for: "slow thermometer" 

Searching for the exact temperature measurements, the brilliant Galileo Galilei discovered this fascinating method. We think its because he got cold while outside at night using his other invention, the telescope. Here's what he figured out. In liquid, a solid body of the same weight and size is compelled to go down as the temperature rises. On the other hand, the solid body goes up in liquid if the temperature falls. In these instruments, the glass balls in the tube differ in weight, and considering the density of the liquid, you are guaranteed that the lowest of the floating balls in the upper part of the cylinder indicates the correct temperature. Each ball has a temperature tag on it so its easily readable.

The production of this instrument is extremely complicated. Each ball is calibrated to within exactly .36 degree Fahrenheit. Any two glass balls differ in weight by only 6/1000 of a gram. Each cylinder is of solid glass construction with a wide glass base to present a low center of gravity to minimize the chance of tipping.

These make wonderful decorative conversation pieces, and they fit in decors ranging from modern to antique. They are certainly eye catching and fun to own, or make great gifts. Nobody is ever going to be unhappy receiving one of these!

Standard units have temperatures marked in Fahrenheit (Celsius is available via special order).  All temperature weights are 24-Karat Gold Plate. The floating bulbs in each of these are multicolored.  Single color bulbs and/or gold base available upon request.  The liquid inside the Galileo is clear and contains paraffin and petroleum distillates, which are found in many household products.  Temperature spheres and thermometer body are individually hand blown by master craftsmen.  Made in the USA.

Reading the Galileo thermometer:

Bulbs all on bottom: The thermometer is too warm. Display the Galileo out of sunlight and away from heat sources.

Bulbs split between top and bottom: The thermometer is working. The lowest of the floating balls in the upper part of the cylinder indicates the correct temperature. 

Bulbs all floating: The thermometer is too cool. Display the Galileo away from air conditioning vents or cold windows.

	We DO NOT accept returns of Galileo Thermometers/Galileo Weather Stations due to the chance of breakage during shipment. Galileo Thermometers that have been repacked often do not survive a second shipping. For that reason, we do not accept returns on this item.
	Since the US Postal Service rates are zone and dimensional dependent, some items might ship FedEx Ground when US Mail is selected. Shipping charges will remain the same as selected on your order.

PRECAUTIONS FOR GALILEO THERMOMETERS

The liquid in the Galileo Thermometer cylinders is completely sealed and can be safely displayed in your home. By following a few basic guidelines, you can enjoy this product for a lifetime. Keep out of reach of small children and pets. Place on level surface where accidental tipping cannot occur. Keep away from sources of heat such as, fireplaces, stoves and radiators. Do not store in your automobile trunk. Keep out of direct sunlight. This product contains paraffin, petroleum distillates, which are found in many household products. The same safety precautions apply.

Should breakage occur, keep away from open flames. Fluid in this product is combustible. Be careful when picking up glass pieces or fragments, they may be sharp. Open all windows to increase ventilation and wipe up excess with damp cloth. Rinse remaining residue from cloth and allow to dry outdoors.

Thoroughly wash hands with soap and water.

If eye contact occurs, flush eye with water for a least five minutes and contact physician.
