    And as usual , the rest of the molten metal is cast into rounds wich will be general purpose .

    The stainless cooking pots give a very nice finish .
    The metal shrinks just enough after cooling down , so that a tap on a flat surface will free the cast from the
    pot . I've used them 5 times now , and they seem to hold their shape .
    No buckling , no deformations .

    I don't know where you are located in the world but I find Sodium Silicate at the Pharmacy (Local Chemist) and even at some grocery stores in small quantities... You can even find it at Farm and Ranch supply houses. One of the traditional uses for it was for "sealing eggs for storage"... Just a clue on other sources to consider when looking for small quantities of sodium silicate. The old common name for it here in the USA is "Water Glass".
