- Editor's Notes
- "We sent you to-day by express sample of insulating compound No. 434B. We would like to know in regard to this sample: ### a. Does it become to soft at ordinary temperatures? ### b. Does it become to brittle at 32 F., or lower? ### c. Is it sufficiently fire proof? ### We may say in regard to this sample that it may not prove to be as fire proof as you could wish, but we can improve upon it. It is very much cheaper than sample 420, and very much easier to make. ### With reference to supplying you with 300 lbs. of insulating material, we have not the facilities here for making such a large quantity in a short time. It would in all probability require two or three weeks for us to furnish you with that amount of material. What we wish to do is, to strike a compound that will meet all your requirements, and then give you all information in regard to making it, so that you can prepare a quantity at your own works for a thoroughly practical test. This answers your letter of 8th instant." Yours very truly, Laboratory of Thomas A. Edison
