Owing to the fact that this material does not crack under the most violent changes of temperature, a 

 Weight Thermometer made from it may be used without the risk of cracking common to all other glasses when a 

 liquid is introduced into a hot tube. This advantage over even the best glasses known prior to the adoption of 

 quartz glass will be much appreciated by all who use, or direct the use of, Weight Thermometers, Ignition Spoons, 

 and other forms of laboratory apparatus. 



2405 T Quartz Glass Ignition Spoons were originally designed for simple qualitative and quanti- 

 tative ignitions, but other uses will readily suggest themselves. Price of Ignition 

 Spoons, as illustrated, 3 in. long over all . . . . . . . . . . per doz.
