Clay Pinch Pots with Melted Marbles

I was very nervous about trying this project, as I was worried about melting glass in my kiln. I had seen several sites online that talked about melting marbles onto clay but they didn't give very detailed info on how the whole process worked. But, we gave it a go....and it worked and has become one of my favourite projects this year! I worked with two Junior ESL classes and we made simple pinch pots. After they had dried, the kids 'drew' designs on with a toothpick and glazed them (including a clear glaze over the top. They then chose three marbles (make sure you use the proper glass ones) and put them into the bottom of their pot. Finally, we crossed our fingers as they went into the kiln!! I love all the results, but I especially like the ones where just the clear rather than the coloured marbles were used.

    1. Hi Sashira, I have a pre-programmed kiln that has a bisque setting and a glaze setting - I used the glaze setting, which I think is around 1200.

  2. Hi Chani

    Your pots turned out fabulous! I'm sure the kids loved making them.

    I've done the project for many years. I always add the marbles to bisque-fired pots, and then fire the glaze/marbles to cone 06.

    1. Rina, I am a pottery instructor and I have four homeschool girls in my current class and we are going to try this project. I am firing a test pot tonight and am going to 06 thanks for your post with a cone number. I would hate to mess up their little pots they are so excited about them.

  3. Hi,
    Thanks for this info. What about those semi-circle shaped glass "beads" that people use to fill vases or put in the bottom of aquariums? I have tons of them and I'm wondering if they would work like the marbles.

    Thanks!
