[AMPS] Heat Paint

[Frank Donovan]

Hello Ian!

Quoting the McMaster-Carr catalog:
"We ship around the world.  Our export department can accomodate most
forms of payment and provide all necessary documentation."
Order telephone number: 908-329-3200 M-F 0700-2100 eastern.  
97% of items ordered from McMaster Carr (over 155,000 products in stock!)
are shipped within eight hours.

The McMaster-Carr catalog lists a full page of temperature indicating
crayons.  The price I quoted was for a kit of 20 crayons that are only
3/4 inches long.  The price goes up to $96.67 (p/n 3224K32) for 2 1/2 inch
crayons!

They also sell the melting (as opposed to color changing) crayons
individually in temperatures from 113 degrees f thru 2500 (yes...  2500)
degrees f.  35 separate temperature indicating crayons are available over
the 113 to 600 degrees f range (aprox 12 degree steps) for $ 7.36 each.
