Mo Mugs

We went to the National Museum of Scotland at the weekend, to see the Lego exhibition and have a look aboot. We found this case of printing plates from Chambers’ encyclopedias. They’re absolutely beautiful.

I saw a video on Instagram showing this technique; you make a shape, then brush on Sodium Silicate, force dry with a heat gun [blow torch etc] then belly out from the inside and the outer skin is dry and deflocculated, so it cracks like this.

If you dry the outside more, you get bigger cracks, but the piece is harder, more fragile and harder to belly out. I would also worry about drying the outside too much and the heat difference cracking through to the base. Also, the inside gets really hot!
