That’s quite a clever setup with the bowls, and the final result is quite pretty. I look forward to getting my GF so I can try something similar.
I’ve been working with acrylics for many years, and I would like to caution you on using your kitchen oven (or anything else you would use to cook food) to do your heat bending. Acrylic has a very small temperature range between being pliable enough to bend and beginning to decompose. It also releases chemicals as it melts, and should always be heat formed in a well ventilated area. Acrylic can also catch fire just outside it’s bending range and is quite toxic when burned.
