Sigh- I purchased a medium size bottle of EnviroTex Lite resin, a month ago (I did checked, the harder was clear according to my eyes), fast forward a month, now it is a little bit yellow. If I go ahead and mix a batch, will it come out yellow or clear? Help!  Huh
If your resin has yellowed in the bottle, then consider it expired. I wouldn't work with it.

Hi everyone! I know bubbles have been asked about dozens of times before but I've tried ALL the solutions I've read about and still having no luck, so thought I might as well as again in case anyone has something new to suggest!

I'm using ICE epoxy resin to fill backless bezels which are about 1cm/half an inch deep (though as I'm adding inclusions that I want scattered throughout the bezel I'm rarely filling it more than half full in one pour). I'm finding that I keep getting teeny TEENY bubbles which I just can't get out for love nor money. As these bezels are backless I want the light to shine through and not have the effect ruined by teeny tiny bubbles! The bubbles seem to occur at the mixing stage.

So far I've tried the following:

- Different mixing sticks (including wood and plastic, round and flat)
- Mixing slowly and gently
- Warming the resin and the hardener before mixing
- Warming just the resin before mixing
- Heating my room to about 73 degrees and making sure humidity is less than 50%
- Sitting the cup holding mixed resin in warm water while it rests before pouring.
- Blowing on the surface of the resin (both in the cup and in the bezels) using a heat gun.
- Pouring the mixed resin in a thin stream into a new, clean cup (just seemed to make more bubbles.)

Using these methods I've cut down the number of bubbles but I want them completely GONE. Anything else I should try? Is my room maybe too hot or too cold? Is there a different resin I should use?

What kind of inclusions are you using - if you are using things like feathers or flowers, there may be some air bubbles that will develop because there may be a lot of surface area along all the tiny little edges and you may not be able to get rid of everything.  But you could also dip things into some resin, before laying it into your resin pieces too to help reduce some bubbles.  You could use something sharp like a pin or toothpick to help lift the bubbles up to the surface and pop them with your warm breath.  I also will carefully wave a match over the surface to pop bubbles too - though ones deep down will still need something to coax it up - like the sharp pin.  You could try thinner pours when layering different things.  You could try warming your room more - cold apparently can cause more fine bubbles, though I haven't seen it myself.  Sometimes, some really fine bubbles may not even show until the piece has started drying.  If it is really fine bubbles, you may even try to add some pearl mica powder that adds some iridescence, and may trick the eye into not seeing the bubbles.

One thing I read about the Ice Resin brand is a recommendation to let it rest for 5 min after stirring for a total of 3 min (in two cups--not waxed cups of course).

Dipping the beads in resin and getting them "wet" all around before adding to your bezels should help prevent all the tiny bubbles that would otherwise get caught between them.

And btw, it's the CO2 from match flames and hair dryers, etc, that pops the bubbles, not the heat.  So one good method is to breathe out through a straw directly over any bubbles which will direct CO2 where you want it.

You could try another resin but Ice Resin is one of the ones that domes.  That comes with some problems though compared to "regular" resins (including that it must be sealed with polyurethane/etc) so you might want to switch to one of those if the warming, low humidity, thorough mixing (not nec. slowly), no wax on cups, dipping, resting, and CO2 don't work.  For small items a longer-setting epoxy resin can even work (like Devcon 2 Ton, 30 min Set).

For more on the different brands and problems of epoxy resins, and also polyester resins, check out my answers in these previous questions over at YahooAnswers:
... and Easy Cast info/instructions, many of which apply to other epoxy resins:
using resins in permanent cells and also in temporary molds, cabochons, etc:

does anyone know what the best kind of mold would be to make resin oendants, etc? i cannot find any ice cube trays small enought for what i want and no candy molds or anything. Im thinking if making my own molds out of plaster or paris or clay. has anyone tried this?

Hi!  I make cabochons using paint pallettes from Joanne's! You can put them in the freezer once they are completely cured and hardened for a few minutes and they pop right out!   Those are necklaces I make using them, they are flat on the back and because the surface of the pallette is smooth they turn out shiny!

I had an idea for a crafted item and bought some resin a while ago. It was hard to find anyone selling anything like it around here, so when I found a store selling it I bought what they had. After reading up on resin casting I realise what I have is polyester resin. Um... Any words of advice for a newbie? Seems a bit scary to me :/

If you still have your receipt, you may want to return or exchange it. Wink

Here is a helpful article on poly resin vs. epoxy resin. http://www.overtons.com/assets/prodman/Polyester20Resin20Final.pdf
