Preserve Insects in Resin




Introduction: Preserve Insects in Resin

About: I enjoy most forms of art. I am learning how to woodwork. I enjoy gardening and growing anything. I love fishing but don't get to very often. I am very interested in philosophy and I consider myself a modern...

Do you have an insect you would like to display in a cool and interesting fashion? Then, you might be interested in preserving it in resin. Work in a well ventilated area. Make an attempt not to get any on your hands. It is very hard to clean off. I'm aware that another Instructable has been posted on this but my way is simpler and appeals to those that don't have a table saw.

Step 1: Materials

Casting resin, Specimen, Ice cube tray or other ideal mold, Catalyst, Mixing cup (DO NOT USE STYROFOAM), Stirring stick

Step 2: Measure

Measure the depth of the ice tray well. If you buy resin that comes with catalyst, the package will tell you how much catalyst to add.

Step 3: Fill

Fill your well halfway. Place your specimen. Wait a little bit. Be patient. If you don't wait, your specimen will surface. Do not allow it to drift or it will dry abnormally. While waiting for your specimen to stay in place, cover it with something. Polyester resin does not cure in the presence of air. Cover the rest of your subject after 5 minutes.

Step 4: Dry

Set it in a clean and dry area. It will harden eventually. Curing times will vary depending on how much resin is used. Cover tray with card board or anything to prevent air contact.

Step 5: Pop It Out

Carefully, remove your creation from the tray. Be careful not to break it. Wait for 10 hours just to be safe. This will allow for maximum curing.

Step 6: Display

Voila, you have a beautiful specimen encased in resin. Display it on your shelf and amaze your guests. I would advise you not to put it in your drink as it is a toxic chemical.

    This sounds like nit-picking, but I am interested in embedding some insects and found this site very useful. But somehow, somebody in the field started using the word 'dry' instead of 'cure'. As far as I know it may have been some of the manufacturers of the products. If so that's a shame because they should know better. When a resin is mixed with a catalyst a chemical reaction is involved. Once that is complete you have a new compound. There is no drying involved at all. Drying implies the loss of water or some other volatile liquid. 'Curing' is the proper word for what's involved in plastic embedding.

    I'm looking to preserve one of those chalky 'be mine' Valentine's day hearts, perhaps as a necklace. Is there any other steps or precautions that I should take to do that?

    Could this be used to extract DNA at a later date? For ecample if you put a tooth in the resin , would DNA be preserved?

    It would probably last a bit longer in the resin as it wouldn't be subject to decay. Of course DNA has a half life of about 500 years, and no amount of resin can stop that.

    I work at a school could I do this with larger items like a dissected frog for demonstrative purposes? It should work the same correct? It would be significantly cheaper then purchasing them premade.

    Yeah, it should be possible. I've seen sites online that sell dissected toads and pigeons preserved in resin at least.

    hey i thoght of this too but you must remove all the air inside the frog too make sure it dossent rot inside the hard sculpture. hope this helps

    A catylyst is something im chemistry that speeds up a reaction, but is not used in it.

    An example is the catalytic converter on cars. They contain platinum, which speeds the decomposition of Carbon Monoxide into Carbon Dioxode.

    With acrylics, its something thst speeds the hardening process.

    i was wondering how that was done. im gonna try this on a dried up seahorse i found at work...thx

    Okay but where do you find the casting resin? I was told years ago by a doctor that if I could put "bad bugs" into a resin or acrylic block where they can use it to demonstrate to a patient "this is what a black widow looks like" " this is what a brown recluse spider looks like" "this is what a yellowjacket" looks like that, he thought many doctors would snap 'em up!!

    if you make a difuse led table, and putting the resin insects inside?? (sorry my english!)

    Fantastic! Many thanks for the simple and easy to follow instructions. I have a collection of things I've been wanting to 'float' in resin and the ice cube tray makes the perfect container!

    I have an amazing picture of a spider and its egg sack I did after learning how to do it from your instructable, if you want to post it. how might I send it?

    That's awesome I could use this as my project thanks! :-)

    I did this many years ago (some 40+) with flowers, photos and coloured the resin using ink from ball-point pens.
