Does the resin heat up as it hardens? I'm looking to cast live flowers in this and don't want to cook them.

No. Mix about 7-10 drops of catalyst (the hotter it is outside, the less you use) into about 3 cups of resin. I cast many live plants and they are always fine :-)

No need to buy a hardener as this kit contains one bottle for resin and one for hardener and its equal parts mixing, great stuff and easy to work with.i use it for making trolling lure heads( fishing) and it forms bubbles sometimes due to mixing and temp so i put it into a homemade air compressed chamber to collapse or push the air bubbles out before it hardens. And when it sets i sand it down (with water) using a rough sand paper( 200), then 400,600 and then last 1500( this gives a nice finish) and the you can polish using any kind of polishing compound.good luck

If you have tried using a hair dryer on it to try to get it to harden, I would say you either have to start over, or try mixing another small batch and pouring over what you have, sometimes it will work and harden up. Make sure your measuring, stirring correctly and the room temp and resin temp is warm enough, if too cold won't cure.

I have used it with craft paint and painted tops of wooden stumps for decoration but it doesn't last long. I think the heat and direct sunlight is what causes the issue. But that was also craft paint so that could be it also

I'm sure it depends on the BTUs as well as the viscosity of the contents, but I've never had an issue with scorching (in a homebrewing application). However, I think the gauge of metal is uniform over the entire surface of the pot.

It is stamped on the bottom "hand wash only" and does not have an indication that it is oven-safe. The porcelain/china is relatively thin, so I would assume it would not do well on a burner without a heat diffuser and on a lower temperature. Despite the hysterics of one answerer, I do not think it is an unreasonable question. I have not used this teapot (because of its oval shape), but have used many porcelain/thinner ceramic teapots on my charcoal-burning samovar and they do get some heat and flames from the bottom. Other than brown discoloration on the bottom, they have done well -- Except I did crack a very beautiful and very large fancy teapot when I accidentally put it on the samovar dry :( It is stamped on the bottom "hand wash only" and does not have an indication that it is oven-safe.

Yes you can. Just keep it cold or refrigerated before u use it in ur play because it melts. And I recommend you use Pam baking spray on the mold to take it out easier.

Don't think this is good idea because even mixing a small amount (1/2oz) could produce heat reaction..You should always use the correct harder with the correct resin.. They are all different..

Yes, it is a good quality of rigid plastic resin. It does not have any drain holes on the bottom so be careful if you decide to drill holes. Be warned it's tricky to do without splintering the pot. I have four of these with large geraniums in them, and with a strong wind they will blow over due to the lightweight characteristics of the pot.

Not sure what you are experiencing. I had no such problem but used it indoors last fall. If it is cool, it is likely to take longer to cure. Humidity in the air is also a factor and certainly if the concrete has water content from washing, the cure could be prolonged. Likewise, wrong ratio of resin and the hardener could do the same. And stirring it thoroughly is necessary. My advise would be to let it sit until it is NOT tacky. If that never happens, I would add very thin coat of sand and brush it lightly. eventually, it will harden up.

I tried putting a pot of boiling water on it and that didn't seem to do it any harm. Silicone can be quite heat tolerant but I'm not sure if this particular item would stand up to oven temperatures.

Not sure of curing process of instamorh but unless it causes heat enough to degrade the surface of the impression you shouldn't have a problem. I've used the molds to cast most two part materials and have only run into one problem with an ectothermic reaction. I could salvage the Instant Mold material by reheating, though the costly material being used for the positive was a total loss. See if you can contact instamorh to find out if there is any heating involved with the transitional state of their product, if it's not to hot you can sill use the Instant Mold.

I tried the sharpie dying a bit on it and that method does work but as far as heat you have to be careful.. It can take some heat but not much.. If you use too much you'll fry it.. I did to an end which I was trimming anyways :P

Hi James: My experience is that direct sunlight does NOT change the color. However, I should say that long exposure to the very hot sun tends to make the resin pliable -- not gooey. But it re-hardens as soon as cool. Hope this helps. Bear in mind that I live in Tucson....the June sun is most direct & HOT.

Yes, I have used it one a couple glass flower vases and it's worked quite well. Takes at least 4-6 hours to dry. I believe the directions say something about using heat or steam to make it rise more but the way you see it bubbled on the glass is how it will dry.

Yes...I believe people bake items in oven to make this paint permanent. I am unsure of temp./time, but if no one answers with that info, try Googling. I know that I found that info accidentally when I Googled this set for more information/reviews prior to my purchase...I just don't recall the details!

It doesn't really harden. It's basically like a liquid chalk substance. It's closer to paint in texture than something that hardens. It does dry extremely fast. I'd say within minutes you could touch it and it would not rub onto your hand (in the summer anyway). I used it on grass.
