Since the ban of borax about 7 years ago, I haven’t seen Slime very often. Seems like the alternatives aren’t much enjoyed.

Borax also acts as preservative, it increases pH, and functions as a buffer… it does so many things and that’s one of the reasons why it’s so hard to find an alternative. The ban was under others justified by the existence of alternatives; however, there are only alternatives for single effects but not the whole thing. Don’t get me wrong, this is regret only on a chemical level and I think it was the right decision to ban borax/boric acid.

Exactly! I agree with you. The incorrect usage of borax and boric acid can cause problems.
But anyways, I liked a lot our discussion and I will try some new things with Alum. 
I’ll come back to tell you

Have you tried making Elmers Glue slime?

Hi Perry!
Thank you for your help
Yes, I’ve. And it’s very good, but unstable after long periods (about 5 months it starts to deteriorate and it becomes aquous and very goey lol).

Hey there! Thank you so much for replying my post

I’m going to see if my basic formulation is stable using aluminium.

My problem with the shelf life is actually related to the stability of the reaction itself. Most of the polymers I’ve tried are unstable when I’m note using borax.
I run tests to see if the formulation is stable or not, but it’s hard to maintain everything (texture, smell, and sticknes.
There is also something about buffering the reaction right, but it’s not working with others materials.

Also, do you know if the slimes made in EU, or in Canada are aluminium based? Borax is forbidden in those places, so I was wondering what it is they use.

Thanks again.  <3
