    Hi ,

    Second question for today.

    I am an totally beginner to the glass art and I learned that there is such a thing called glass clay. ı read some posts and Kaiser Glass described to make your own glass clay.

    And I read that there is bronze clay thing which it was possible to fire with a torch and make your jewellery.

    I want to make my optical glass sculpture as big as possible with may be glass clay. Size is a piece like Orrefors Swedish Glass.

    First :

    Would it be transparent or what I should do to it to make it transparent ?

    Is it possible to sinter with torch or in a mold and in a pit fire ?


    Thank you ,

    You cannot use glass clay to make a clear project. Fusing the clay traps tiny air bubbles causing the clay to be opaque or, at very best, translucent.

    I know a little(not much) about bronze clay, but I do know that it cannot be torch fired. It needs to be fired in a reducing environment. They fire it in a pan of charcoal to keep the oxygen out. out.

    Hi Mustafa

    Have a look here for views of the product “GlasClay” … http://www.delphiglass.com/fusing-sale/fusing-kits-sale/glasclay-kit-96-coe and note that there is a book available on the topic which may be worth reading before you commit to spending toomuch money : http://www.delphiglass.com/books-dvds-software/fusing-books/glasclay-basics .

    And, as Barry states, it is opaque by the look of the examples.

    Good luck and enjoy creating
