What is this clay and rubberish metarial?

TL;DR Summary
I mixed crafting glue with rubber dust and rubbed it on my hand for some reason and it made this clayish ball which after some time acts more like rubber than clay. What is this?
I was feeling very bored so I wanted to play with my surroundings and I had:

And Rubber Dust:

Near me so I (for some reason) mixed them together and rubbed them on my hand. After some time it started to take a spherical shape. It lost the stickiness of glue and started acting like clay, it could be stretched too. After some more time it lost its clay property and started acting like rubber. It could still be stretched but not so much. Touching it feels like plastic and it also works like a dustless kinda less efficient pencil eraser.

Why? Like I mixed glue and rubber "dust" together and rubbed it on my hand so why did it became a clayish metarial? And then why did it even became a rubberish plastic type metarial after some time? Also there wasn't much rubber dust so how did it also worked like a pencil eraser?

What kind of glue is crafting glue?
Chemically?

polyvinyl acetate (PVA), a vinyl polymer and type of thermoplastic.

On inspection, it looks like superball material but you'd need a chemist to tell you what you've made.

Superballs are made of polybutadiene:

Oh I will ask my chemistry teacher what I made.

Without getting into the chemistry, you just glued rubber to rubber. Probably not the same kind of rubber. Most glue is a rubber material, that has been dissolved into a solvent. When you glue something together, your spreading the rubber out very thin. Then the solvent evaporates, and you have the very thin layer of rubber holding the 2 parts together. Many glues are polystyrene or polyurethane based rubbers, technically called an elastomer. Very simplified explanation.

In your case one of the elastomers was the Polyvinyl (acetate). Another more common version of this is PVC (Polyvinyl chloride)
