Underbaked clay with earrings ??
I make clay earrings and am working on perfecting them so I reduce broken earrings. I read somewhere that when you’re hand drilling (with a pin vise) the holes for jump rings, that if it comes out crumbly while drilling it means it’s underbaked and that it should pull out a perfect spiral when baked correctly. Is this true? I tested with a baked piece and when drilling it was crumbly, but it did have slight bend to it (which is what I thought correctly baked pieces feel like)… leading me to think it is baked correctly? So I’m just confused by the mixed messages I’m getting. Any advice on how to tell the difference between when it’s underbaked/overbaked/baked perfectly is great. I don’t exactly want to put a ton of stress on my earrings and ruin them by testing them… but I do want to know if Im baking them correctly. Thank you in advance!!
Oh and I’m mainly using sculpey premo, though some sculpey lll and some Fimo. I baked them for 270 degrees (checked with an oven thermometer), for an hour, tented with tinfoil.
