If you’ve spent anytime at all with resin, you have run into resin casting issues or problems with resin curing. (Myself included!) I’m going to share with you a few of the problems I have run into and a few resin jewelry making techniques to help.
1. Make sure your area is clean. (and clean some more) I don’t know why, but Murphy’s Law always applies when it comes to dust and resin. (cat hair is even worse). If you’re lucky enough to have a dedicated room for your resin crafting and jewelry making, keep everyone and everything out if possible. (especially the pets) Sweep, mop and vacuum regularly to keep dust to a minimum. I would still recommend putting a solid dome over projects while they’re curing and make sure that container is clean as well.
2. If you’re putting something else besides resin into your project, make sure it is dry OR very well sealed. Resin HATES moisture. Any little bit of extra moisture can keep your resin from curing properly. Read how to properly seal papers and inclusions for resin jewelry making.
3. If you’re adding liquid colorants, add as little as possible. Yes, the liquid colorant is a liquid, so since resin hates liquid (read number 2 above), adding more than a little bit can mess up the resin curing time (if it even cures at all). Of course this is all relative — two drops of colorant in a 10 ml mix isn’t like 2 drops of colorant in a 100 ml mix.
4. Bubbles. A few ways to avoid bubbles is to keep them from forming. Make sure your resin is warm, 70 degrees or so, (place the resin containers in a warm water bath for an hour to help bring up the temperature if it’s not warm enough) and mix the two parts together in a deliberate fashion without whipping.
5. Resin comes out to a gooey mess. This usually comes down to one of two things:
- moisture — either in the resin, mixing material (water left after cleaning out a mixing cup), inclusions (adding a non-dried flower for example) or adding in too much liquid pigment
- not mixing properly — this is the one I usually fall into. I won’t say you can’t mix too much, but my personal rule is to mix for 10 percent of the total pot time. For example, the Resin Obsession is 25 minute pot time, so you should plan on mixing for 2 1/2 minutes. I have tried to guess how well it is mixed by looking at it only to find that a timer works best. Also be sure to scrape your sides and mixing stick several times while mixing your resin.
My best advice I can give to you about resin casting problems: Keep a journal!
I don’t know how many times I’ve done that something that has worked (or hasn’t worked!) only to wonder what I did. Seriously. Best advice I can give you. Write it down!!
What are some of your suggestions?
