Breast milk preservation

Our own tested method in 7 steps. 

How we preserve your breast milk 

Ingredients ... Just two. 

  1. Your breast milk 
  2. our clear solvent 

Here at Sentimental Keepsake, we can ensure you that no other substance is added to your milk. We do not add clay, Sculpey, wax or glues to preserve. It is your breast milk & solvent only. And to put your mind at ease we have provided this process in photos. 

Why choose us? Because we will provide you with a photo of your own precious liquid love. moments after it has been preserved. Either by email or phone, the choice is yours. As well as this preservation information. (please note, when you order from us all we ask is that you state in the comments box that you would like a photo, as we only provide if asked). We also have a FREE gift page for our lovely customers, when they purchase a keepsake. They may choose to have a second Keepsake as a gift to give their child when they are older. In the form of a tiny bottle with preserved breast milk to match your jewellery or plain.. free gift for you, page. 


Step... 1 

Getting together all the things I need such as gloves, hob, utensils and more importantly my respiratory gas mask. Due to the chemical solvent being added we require protective wear.

A small amount of clear chemical solvent is added to your breast milk milk that will preserve your milk and turn it into stone. You may see breast milk jewellery as a top-secret business where artists never give their methods away. But at sentimental Keepsake, the secret is only in our jewellery design, which is unique to our brand.  

Which is why we are showing you our preservation methods, so you as the lovely customer know we only use your breast milk and no substitute. We use a syringe or pipette to put in our solvent. I hear you ask "what solvent do you use?" I do not tell people, not because it is a secret as you can do your own information gathering on google on chemical preservation, it is easy to find. It is because when I first experimented with the chemical I nearly ended up in the hospital due to chemical inhalation. I would not like to be responsible for any of you harming yourselves at my instruction.

Into our special pan goes your breast milk and solvent. We usually add the solvent in after the milk goes into the pan, but for image purposes, we didn't.

After 8 minutes or so your milk simmers down as it is the fats in your breast milk that are left to create the milk stone.

After 10 minutes, sometimes more, your breast milk is preserved and ready to be spread out onto the greaseproof paper or paper towel. Your breast milk order number stays with your breast milk throughout the process from intake to keepsake home time, and I only work preserving one at a time. At this point, your breast milk is a soft very sticky consistency.

Step ...5

After it comes out of our pan, it can literally start to harden straight away as in this photo. Or it can take much longer sometimes even up to a week to turn into stone. The colour of your breast milk stone depends solely on the fats in your milk. it has nothing to do with the colour your milk is when it is expressed. I have had very creamy yellow to brown breast milk dry chalk white, and almost transparent breast milk dry creamy yellow. It all depends. I have been asked, "what is your favourite part of breast milk jewellery making?" believe it or not it is actually the preserving faze. I find it fascinating to watch how it responds and reacts to the preservation method and how the finished milk stone will look, to me it is rather a beautiful thing. 

(I will soon do a post on breast milk as I have been asked many a time why does my breast milk look brown? I have even had breast milk with a green or a red/blue tint. Please don't be to alarmed, this can happen for various reasons such as diet and the foods you eat. I have also had Mums say "I don't like the idea of having a brown or green bead even though it is special to me, I want it white". Well we do colour-match the tint to your breast milk colour but in examples like this we will make the tint a more aesthetically pleasing colour for you, so please don't worry and the best thing is that it is still your breast milk inside although you may from time to time faintly see the darker fragments depending on how finely they grind down)

The milk stone is crushed down to form a powder-like consistency before it is made into your jewellery with resins to set it and keep it safe forever. 

You do have to be careful with resin jewellery as it is essentially a plastic, it can scratch or come loose from the fixtures if submerged in water. But if you follow the guidelines on taking care of your jewellery then you can enjoy it for decades to come. 

We take pride in making all our pieces with love, it really is an honour for us and we appreciate each and every one of our customers. So you can see now, that at Sentimental Keepsake we really do perfectly and professionally preserve your very own breast milk. 

Although there is no such thing as perfection when you buy handcrafted pieces from any Artist, resin sometimes set's with little bubbles etc... we love the little bubbles they make your piece unique. Besides, unless under a magnifying glass you won't see imperfections to well. We deem all that we make as perfectly beautiful in its own right as it is sentimental and precious to you. 

We hope you liked this explanation of breast milk preservation. We love customers to feel free to share. We do notice and appreciate it. 

Much Love
