Hi Sherry! AfG oval 13 is a glass kiln, with a max temp of 1700. The approximate cone value equivalency is cone 09. If you have questions, always feel free to call and talk shop! We love to help. -Jenn
Your best bet would be to call, I'm local and went in to order a kiln just a few days ago. Most models have different Amp options and I believe all have a high fire cone 10 option :)
