Casting Craft Resin from Michaels without pressure?

If I am just casting PR without anything in it, I don't use pressure (or vacuum or vibration). PR hardens slow enough that the bubbles can float out. That being said, you don't want to mix a ton of bubbles in, either. You aren't making a smoothie.
 
I just turned a pen out of the Casting Craft Easycraft with orange enamel paint and pearlex and it came out perfect. Not a single bubble and turned like butter.

Saw a video on youtube where someone uses vibration (orbital sander under table) to remove the bubbles.. does this work ok?

Dont have a pot yet but would like to try a few things with the resin.

Thanks!

As mentioned, be careful stirring. I've put small molds on a scroll saw table
to help release the bubbles, but beware that bubbles can form during the
cure. Vibration can help release the ones that are already there, but the
new ones .. not so much.

Warming your mold, warming the resin and dusting the mold with baby powder
can all help keep the bubbles to a minumum.

Also, the bubbles can't be seen as easily in opaque colored resins. They
might not be seen as bubbles if they are there, but you might see them
as imperfections in the surface as you turn. They'll fill in fine with a coating
of CA though.

If you are going to dust the molds with baby powder, put some powder in a metal tin then set it in your toaster/warming/curing oven, to drive off any absorbed moisture as most talcs and cornstarches absorb moisture from the atmosphere and moisture is bad for resin.

Good point .. humidity is about to become a major factor in many areas..
 
I poured my resin, added the orange paint and mixed it well and then added the pearex. I poured into my mold and put a lamp about 5 inches from the mold and they were hard to the touch in about three hours, but I waited until the next day before releasing them from the mold. They came out and were not even tacky.
