: I said "heated discussion", not "argument.
Not to start it all over again, BUT. My business is 99% high end restoration for many years. I know a few things. One is what should and should not be in putty for long term quaity work. Based on MM putty claims, I figured they used plaster and terps in their mix. I bought the product and as you stated there are no ingredients listed. I Emailed them and asked for a MSDS, again no ingredients, so I Emailed them agian and asked out right, "what's in the putty". I was told that it was a 100 years old formular, and they would not say what was in it. So I posted this on the WC board. There was alot of pro and con, and finally MM posted what was in the mix.
So that's basicly the story.
: Vic,
: What was the argument about?

: : : Vic,

: : : I have looked all over the label and it says nothing about having these ingredients.

: : : : Any putty/cement claims to add alot of strenght and a fast drying time has additives that are NOT good for long term stained glass life. The additives are plaster,potland cement,turps,japan drier and other things. Miracle Mud uses plaster and turps. Plaster is not good because it is hydroscopic, that is, it absorbs mosture and can leach out onto the glass. This can cause the glass to decay over time. Turps dries out the putty/cement too fast. The thing to remember is how long is the window going to last. Stained glass generally needs to be restored around 100 years. If you feel that your window will be restored at some point that use proper putty (linseed oil and whiting), if no one will care to restore your window use what ever product you want. The additives that I spoke of should NEVER be used in quality restoration.
: : After a rather heated discussion on another board. The manufactures of the Mudd gave out the ingredients.
