LOL, Diana, only if you can get the wee one to sit perfectly still
while the mold sets. ;-)

I have a quick question about the Miracle Mold that I dind't find
mention of in your FAQ. With miracle mold and one of the other 2-part
silicone type mix and set mold making products, I sometimes have
trouble with air bubbles appearing on the surface of the mold,
apparently while it's setting. I try to make sure the surface is
clean, but I still get bubbles, always on the smooth surface/open
areas. Any tips on how to minimize this?

Mary T. 8-) ...sorta wondering if altitude and/or temperature has
anything to do w/this?

Hi Mary! As Diane mentioned, sometimes overmixing can incorporate
bubbles.
Also, sometimes smooth/glassy surfaces can be a bit troublesome to
mold. Super detailed objects generally are no problem to mold, but when
you are doing a smooth/glassy surface, there is just nowhere for those
little airpockets to go. With a detailed object, there are lots of
opportunities for the air to get released.

There is a technique that I really need to photo for my FAQ to describe
what to do in that case. Basically, you *shear* your object into the
Miracle Mold, rather than push it straight in. In other words, you're
trying to push away the excess air that may become trapped in the
mold.

I hope that makes sense. It's easier as a visual.

Also, often you can carefully poke into the airpockets with a needle.
The air escapes and the mold flattens back down. Worth a try, eh?

Hope you're otherwise enjoying your moldmaking.

Cheers!

Aha! Thank you Diane,

also, I found fewer bubbles with the fresh batch--after it sat in my shelf for
six months, the molds I made did have a few tiny bubbles, as opposed to the
first ones which had none. I'm at high altitude, and I mix the MM by hand, not
using the pasta roller. Also, do a final squeeze/impaction of the MM lump
before using it. Press it hard in on itself and onto the work surface to force
out any hiding bubbles.

I think using the machine definately mixes in more bubbles, at least it did in
my one experiment. So I do it by hand only now.

------------ Well, once you shear your object in, then firm the mold
material around the object. I kind of cup it in my hands and push it
all together to make it conform.

Me too!!! the pasta machine did NOT work well for MM. But I always try to push
the envelope when using new products. I am very much a "Why?/Why Not?" kind of
person.
