    I have just decided to work with bitumen , widely available and result is my taste. One canadian researcher did petrograph photographic process with bitumen found between rocks in Athabasca area.

    I memorised the process and I want to buy bitumen but I dont know which. There is 60/70 and 80/100 grades. And I learned there is sulfure processed and other processed ones.

    Which bitumen should I buy ?

    Thanks,

    It would be nice to learn more about this process with you.
    The very basics are there in the web, but the details would be really interesting to know.
