Hi Silver,

I tried to post this last night but somehow lost the post. The mortar dye I used is to tint mortar such as BrickSet or ThinSet. There is a concrete or Portland dye, which is next by the way, that is a little different than the mortar dye.

When using the mortar or portland dye, you need to get an MSDS sheet to make sure it has not been made with flammables or combustibles. It can be made with these.

On the set part, I am afraid I am chemistery illiterate. I thought I had read previously where vinegar did create a set. I am probably wrong on this. I also use Rit and have had great results although some find it objectionable because it doesn't have an acid base. Mike Connor has done some fantistic documentation regarding dying furs and feathers.

I will have to try to find some Alum and give that a whirl. Thanks for the information about this.


Flymaker2, thanks for the compliment and the feed back.
