VGP says:

do you guys have a video about having a Glass casting and turning it into silicone rubber? or could you guide me to the smooth-on pack I need to make a silicone rubber from a glass casting? thanks

Nicolas Evensen says:

Would this technique work to make Plaster-of-Paris molds?

Adrian Alob says:

Hm… I don’t know… Most fake anemones look quite stiff… Unlike the real ones, I love the movement of the real ones..

Çok guzel

Anon5K says:

I would like to make a rigid material casting of a red tail hawk, with a plexiglass red tail to for sun reflections. Or is that a piece for a casting company to do? The other thing I was thinking was to just sculpt the tail in some red translucent material but do not know what to use. Any suggestions?

animateclay says:

Just a tip I learned casting full scale hands in a mold similar to this…. you can blow compressed air into those holes as you pull parts out. So if you mold a complex piece with fingers/tentacles and the clay breaks off, tapping the mold upside down while blowing air in can get those parts loose.

wonderful,, thx.

Triad3Force says:

It looked easy enough until in involved getting a vacuum chamber hehe. However, I guess it would be worth investing in all the tools and materials if you were selling what you make with the molds. Or if you were making a lot of those for a big aquarium.

love this jazz its cool and sexey nunna says:

Joe Scrivens says:

Hyacinth Bewry says:

You kidding me? This is aaahsome!!!!

chase says:

I think it’s cool what you made but I have to ask.

Has this product and all the components used been tested for leaching and is it FDA approved? (Not that I hold the FDA’s approvals as absolute but…)

Can you provide a link to the type testing, the results and who did the testing?


saiqlo says:

What model is the chamber used to remove the bubbles?

Ambrosius Malachai says:

TIP: Cut the hot glue at the base of the bucket to remove the bucket without cutting it. Then use the bucket to hold the mold together instead of rubber bands.
