ryelite in potting mix/garden?

We have a small plant nursery and we moved! In our old location we simply went to the local landscape yard and bought it a trailer at the time. The landscape yard here doesn't do it and we are working on the mix. There is a quarry close by and they have ryelite and as far as we understand it has similar qualities like scoria. Does anyone knows anythng about the material?
We also want to use it in our garden with extremely bad drainage, clay and two years of rain.

What type of material were you getting before?
- Course gravel or sand
I looked up the product and it does not seem to be a suitable soil admixture at all.
"What is the rhyolite used for?
Rhyolite is suitable as aggregate, fill-in construction, building material and road industries, decorative rock in landscaping, cutting tool, abrasive and jewelry."
I take it you are looking to open the sol up, road fill will certainly seal it up.
