Irreversible Thermochromic Inks
« on: April 03, 2014, 06:22:01 AM »
Hi everyone!

I want to prepare a type of ink solution that it should be stored in refrigerator or any cooler system( temp. +6, +7'C ) when out from refrigerator it changes color for instance blue form to light blue form or another different color form when expose to heat. However , this should be irreversible exactly. Actually this technique based on a low temperature activated ink according to articles. Have you any idea about this? Thanks..

We get this sort of question from time to time.  It turns out that the Omega Corporation has this sort of ting done in every possible way.  And surely you can find small volumes from other corporations for sale from any laboratory supplier.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
