I’ve ordered a couple of silicone ice cube trays and some glass measuring cylinders for low volume.
This new photograph was taken at noon the day after potting, when some 15 hours had passed. This is backlit so you can see the quantity and size of bubbles. In normal daylight the bubbles are barely visible, though it’s not jewellery standard by any means. I’ll want to see if the presence of these bubbles has any effect on the mechanical, thermal or electrical properties. My initial feelings are that this is good enough for my needs, but we’ll see.
I’ll remove it from the mould this evening after 24 hours, which is supposed to be long enough for curing. The room temperature, by the way, is in the vicinity of 20C.
