question on bubbles...

[mranum]

I wasn't even going to turn this down. I cast it a week ago in PR and when I pulled it from the mold all the feather tips were covered in jillions of teeny tiny bubbles. Almost frost like look to it. Mad, I tossed it to the side and didnt look at it again until this morning and 90+% of those air bubbles were gone. I missed them while taking these pics, must have just been out of view but they are there.

Is this..or can this be an example of a resin that hadn't fully cured yet? Shop temp was in the upper 60's. I used 3 drops catalist per ounce. The PR I used was Castin Craft.

I was under the impression that if there were bubbles when the resin set, they were there for good.

FWIW, rod builders coated the feathers with color preserver to prevent bubbles or moving on the rod blank.
Would casting and then using a vacuum to pull the bubbles out? Still learning.

Well, they say that your hair and fingernails keep growing for a bit after you kick the bucket, so maybe the feathers needed the air in the bubbles to grow into the bubbles and then pegged it.
Just a theory, mind you....:biggrin:
