Preserving breast milk in resin

If you have been in the breastfeeding mummies circle, you would most probably have heard of Breast Milk jewelry at one point or another. Resin art is not something new, but preserving breast milk in resin is relatively unheard of until recent years.

Many companies which offer this breast milk preserving service are based overseas. It may take several weeks to months before your order can be fulfilled. I know this myself since I have ordered a few items from these overseas makers. With increasing demand, some Singaporean mummies are also starting online breast milk jewelry business - you will find a good listing by doing a Google search.

The technique for preserving breast milk is a well guarded trade secret. Until now, you won't be able to find answers on the Internet. It's like a big mystery which nobody wants to let you know.

Interesting, the makers of these breast milk jewelry mentioned that "there were at least 5-6 steps" involved in the preservation process and "no solvent was used". I notice the breast milk jewelry I bought from the overseas makers were of a different shade of white compared to my freshly pumped breast milk. I am very sure the milk has been altered when they are trying to solidify the milk into resin.

After multiple experiments and repeated failures, I concluded that there are millions of bacteria and enzymes in breast milk which cannot be destroyed by heat or other sterilisation techniques alone. See bottom photo of a sample I took of an earlier experiment where you see rings of brown matter growing inside the resin - they resemble colonies of bacteria in laboratory experiments.

By some stroke of luck, I found a simple kitchen technique which works to preserve my breastmilk. It has been nearly 3 weeks and I cannot see any bacteria colonies building their homes in the resin at the time of writing this post. I hope these resin remain this way.

I will continue to refine my technique; more interesting photos are coming up. Please post any comments below.
