Can this be used to make a hard mold to use for casting in silicone?

Accepting that I am not an expert, I dont see any reason why it couldnt be used this way. It seperates well when casting inside tin based silicone. I would imagine casting inside will work well. The very liquid viscosity fills in small parts even after adding various silica to specify properties. I am new to polyurethanes and learned you have to be fast in the mold. I wouldnt stir it more than 15 to 30 seconds before you get it in. Much harder than epoxies without fillers. They sell larger volumes on their website.

I really doubt it. The mold is silicone and probably won't take temps that high. I really don't know for sure though. I do know when the pour-able plastic "goes off" its gets uncomfortably hot, but not into those ranges. Sorry, I hope this helps.

I'm not an expert on Silicone but I think it sounds like a good idea - It is non porous and heat resistant so should work - I'm using it in my artwork as a heat resistant, non-stick surface with a glue gun.

I used plasticine to sculpt a mask, then used the silicone to make a mold from it. It works fine, the smooth-on is a liquid so you pour it over the clay and let it dry. I had no problems with the 4 masks I did with it.

No, this mold is made of aluminum, so the temperatures required to melt copper is much higher than what this mold can handle. I suggest an iron mold for what you want.

I think you might be able to- as long as you are only trying to use half the mold (my molds are in the garage somewhere right now)- but I think they are dimensional on both sides, and they are not water tight (egg liquid would leak out- so I'd chill them in a bowl).

Yes, these are tiny cube-shaped molds. I use mine for hard candies, which is much harder to work with than clay. I push my candies out from the back side...it takes a few minutes, but it works well. Since this is silicon and has no air drying holes, etc., it could take awhile for clay to harden in it, but I see no reason why this wouldn't work. Will pass this idea on to my daughter as she loves beads/bead working. Good Luck!

Yes, you can. I have done it several times with highly detailed pieces, and they turned out wonderfully! The resin just popped right out with no problem/residue left, so I was able to use the same mold multiple times.

The mold is high grade silicone and can certainly handle the high temps however, the manufacture is the one that must certify whether the silicone is food grade or not. This is from China and there is just no way to determine from the data provided whether it is food grade or not. Best to go with the ones that say "Food Grade" Silicone, or to purchase where you can talk to the vendor, like on the ETSY web site.

I use this mold strictly for chocolate - sorry I am not able to answer your question.

I don't think there would be a problem. If you have a master fondant figure head, you should have no problem making a mold with this putty if you're using casting resin or epoxy putty or anything that cures chemically.

I've used plaster, and wood putty, as well as polymer clay and resin, and every one of them came out just fine. If the mold would have an easily accessible place to remove the item being molded, it will most likely work just fine. The only issue I had with the quick-set rubber was that it could be stiffer than others and eventually break. If you're only making one copy, you'll be fine. More than 10 copies if it's intricate, you may have a problem. Other silicone rubbers might do a better job for the more intricate items if you're making multiples, but otherwise you'll be fine.

I do not know, I am sorry. I used mine to make "Chalkboard" Paint for use in the house. If the mold is dry, I would expect that you could do so. The carbon fibers and fiberglass should not stick to the mold. If you are worried about it, as previously done with Fiberglass, just put on a light coat of wax to avoid sticking.

Although I haven't used them for that purpose I imagine you can because it's a good quality and flexible silicone. As they come in two halves and would be difficult to feed the bath salt mixture though the small hole in the top of the mold, you could use the halves separately and have semi bath balls!

You should be able to. I use mine for soap, but it is food grade silicone so chocolate would be OK.

The Easy Mold Silicone Rubber can be used to make molds out of non-hardening moldeing clays as lon as the clay is sulfur-free. This is a two-component rubber which does not require a separate hardener. The Castin' Craft Mold Release can be found as item B000XAWQJU. Blick Art Materials does ship to Puerto Rico.

I use mine for soap making and have found the silicone molds extremely easy to use. hope this helps! :-)
