I've recently been experimenting with tack fusing powders at a very low temperature. Typically they are very thinly applied on either a sandblasted or pre-fired surface. The effect I'm interested in achieving is similar to a chalkboard that has just been erased- a filmy very subtle coating of dust...
So my question is: what's the lowest temperature that others have successfully had powders sinter or stick at? Also, did you go straight to process temperature or ... ???
I know my question is a little abstract!
