Moisture. I had this happen to several that I un-molded while still tacky. Over the next hour they turned milky white.

I cant tell by the picture, but if those are really small molds you probably want to heat the molds before casting to help fire the reaction....Thanks to Curtis for this info (and I think it's in the CC instructions).

Are they just white on the outside or all the way through?

 

[danroggensee]

Do not know yet going to turn them today but they look white all the way through.

Dannie

P.S. will let you know after i turn them.

Well i turned them and the were white all the way until i got to the size for the pen and they came out pink not as pink as they should but pink enough to finish the pen
that is was trying to get to.
