What is the diameter of the round beads?

Hello, for small round bead diameter is around 1.5cm (0.5inch), for larger round bead diameter is around 1.9cm (0.7inch). Please check the third photo displayed for detail size of our sphere silicone mold.

How can I fill this so that the top doesn't have a ring around the bead?

Hi there, Thanks for your messages. Maybe you can choose the other mold without a ring hole, thanks for your understanding. Sincerely FUNSHOWCASE

Can these be used with polymer clay and be baked in the oven?

I think these molds can stand the heat, but getting the clay into them might be difficult. Also, I've learned from experience that if you bake (cure) the clay inside of the molds, you will need to cure the clay for a longer period of time because the silicon absorbs a lot of heat and will keep the clay from fully curing. You should do these two things to ensure of proper cure: 1. Increase the baking temperature by a few degrees (no less than 5) 2. Bake for a longer period of time (add an additional 10-15 minutes. Remember to cover/tent your beads to keep them from burning and let them cool before trying to remove them from the mold. If they are difficult to pop out of the molds after curing, try a little soapy water and they should pop right out. Hope this helps.

Would these beads thread on standard thickness (medium weight) yarn?

It should be able to. The holes aren’t tiny and seem to have pretty decent width. Though if you’re going to use yarn, I suggest making sure the part of the hard you will be “threading” with is sturdy. Maybe twist it tightly and put glue ar the end to harden it a bit.
