Step 1 Set oven rack to a low position to provide plenty of clearance above. Preheat oven to 100°C (no higher). Open kitchen windows to ensure space is ventilated.
Step 2 Carefully place heatproof bowl upside-down on oven tray.
Step 3 Put chosen record in a centred position on top of flat base of heatproof bowl. For best results, you may find it helpful to mark centre of base of bowl with a marker pen, then line mark up with hole in centre of record.
Step 4 Wearing heat resistant gloves throughout the remainder of this project, carefully put tray in oven, taking care not to move record.
Step 5 Keep a close eye on your record, as each record will start to drop at different times, usually 4-8 minutes. When record drops over heatproof bowl, keep your face clear and open oven door. Carefully remove oven tray and set on a heatproof work surface.
Step 6 If you’re happy with how your record has dropped, set it aside to cool. Otherwise, work quickly to mould record into a desired shape over heatproof bowl. For added detail, manipulate record by making folds or ripples around the edges. Leave to cool.
Step 7 Remove record from heatproof bowl. Repeat process for additional bowls.
