"What I hadn’t done was build something for myself. That’s been the exciting but slightly scary bit because my brand has ‘me’ at the heart of everything I do..."

When did you launch Silver Nutshell Jewellery and what gave you the push to start selling?

I launched Silver Nutshell on Etsy in November 2019. I think as makers, we all experience doubt. Are we good enough? Will anyone buy what I make? Working within the creative industries for over 35 years I knew I couldn’t launch until I felt completely confident in my skills as a jewellery maker.

I have a brain like a sponge when it comes to soaking up crafting knowledge and I knew I’d get there. I just didn’t know when. Having achieved the goals I set for myself within my career, I saw silver jewellery making as an opportunity on the horizon, so when in 2018, I left the media business, I knew I was ready for to start a new chapter.

"Sand casting is an ancient technique whereby I create a mould using a special, sticky, slighty damp sand and then pour molten silver into the mould..."

You mainly work with sand casting in sterling silver and your designs are so beautiful! What is your favourite thing about sand casting?

Thank you, I fell in love with sand casting the first time I tried it and the process still fascinates me. I don’t mind admitting that it used to scare me. It’s very noisy and incredibly dangerous if you don’t know what you’re doing. However, I could see that the finished results could be incredible. That’s why I kept trying and it’s now a huge passion of mine. What I love most is the mystery. It’s a process whereby I can do everything possible, make a really accurate mould and still it doesn’t work. Either the molten silver has cooled too quickly on its journey into the mould or the sand has collapsed.

I once cast a gorgeous shell only to discover that it weighted over 24g in solid silver. That’s far too heavy for a pendant. If you wore it, you’d be in danger of knocking yourself out! So, I spent over 10 hours of my weekend course drilling and filing the silver out of the centre of the shell until it weighed less than half of what it was when I started.

I learnt all I could about drilling and filing and the next day, I melted it down! Unless I’m 100% happy with something, I melt it down and I don’t mind that. When sand casting works, it’s a brilliant way to capture all the detail of a shell, a seedpod or an organic shape. I’ll be launching some new pieces later this year, which are much more organic so look out for those.

Can you explain what sand casting involves for those who don't know?

Sand casting is an ancient technique whereby I create a mould using a special, sticky, slighty damp sand and then pour molten silver into the mould. I use two aluminum rings, which are marked so they fit closely together, packing the one half with sand. Dusting the natural shell with talcum powder so it doesn’t stick. Before I press it into the mould, I line up the second ring and pack it with more sand. It’s important to pack carefully because the result you’re trying to achieve needs every grain of sand to follow the contours of the shell. A little hammering at this point also helps!

If you imagine pouring any liquid into a mould, the air has to go somewhere so my next task is to build chimneys into the mould to enable to air to escape quickly as soon as the molten silver fills the space. The silver solidifies instantly so sometimes it works and often it doesn’t. When it works, you’re left with what is called a spru, which is the funnel of silver attached to your piece. It may take me 30-40 minutes to prepare a mould and 10-15 minutes to melt the silver and pour it into the mould. It could then take me anything between one and 10 hours of trimming, filing, adding back details that weren’t picked up in the casting process and finally soldering on a jump ring and that’s when the polishing will start. It may not be fast and it may not always turn out as I expect but that’s why I love it!

Tell us more about the inspiration behind your designs

I am lucky enough to live in a beautiful part of the English countryside so it felt natural that I would design and create silver jewellery, using the wonders of the world around me as my source book. 

This year, more than any other, I’ve needed to spend time feeling connected with the outside world. I spent lockdown with my Mom, who moved in for almost 10 weeks and there were days when we we’re able to go outdoors. Being able to reconnect with nature in my daily life by wearing a silver shell or a silver leaf pendant, really helped me feel part of the natural world.

I’ve been taking close-up photographs of leaves, flowers, seedheads for many years and nature has the most wonderful library of textures and shapes, which look amazing in sterling silver. And being handmade, every single one of my pieces is slightly different, which is the same in nature. No two shells are every identical.

We often see you experimenting with new techniques (such as silver metal clay) - is it important to you that you continue learning new techniques?

My ‘thing’ at work whenever we had management courses was being asked, what motivates you to do what you do. I always said “I’m motivated by change” and that’s exactly why I need to keep learning. I’m like my Dad, who came to the UK not knowing a word of English. He was Hungarian. I still have his diaries and notebooks where he would practise by writing down key phrases from Hungarian to English. Sadly, I can’t really speak any Hungarian. I can only count to ten and say ‘yes’ and ‘no'.

I have a fascination with anything that I’ve not tried before and have a wealth of experience in a lot of different crafts. Silver metal clay is one technique which lends itself really well to creating nature-inspired jewellery. Rolling out a piece of silver clay, pressing it on a piece of bark and making a beautifully textured ring is like the best result I could wish for. Unlike sand casting, which takes time, a lot of thought and is seriously noisy because of the heat of the burner, I find silver metal clay calming and quiet. I’ve been on one really excellent silver metal clay weekend with Joy Funnell Metal Clay Ltd in Dorset and I’d definitely do another.

Watch A Day In The Life Of Silver Nutshell

Join Anna on a day focused on searching for the perfect daisy, creating a mould and turning it into beautiful pendants using metal clay. Not only this we see Anna on a walk in the countryside, doing a photo shoot of her designs, an insight into her birthstone jewellery as well as a peek into her packaging process.

You often attend workshops - tell us about your experience with these!

Oh so you’ve noticed! I do write about my workshop experiences a lot on Instagram because they’ve shaped the type of jeweller that I’ve become.

It’s so important for me to keep learning so I attend weekend workshops @flux_n_flame at least five times a year. I’ve always said to the tutors that I don’t need to take anything home from the workshop, apart from new experiences. I’m motivated by new experiences and have met some amazing silversmiths and learnt so much by attending these workshops.

I believe workshops, whether in person or online are the best way to learn anything. We’ve all become adept at online learning this year and I’ll admit that I enjoy that too. I can take things at my own pace, skip the bits I already know and focus on the techniques that I really want to learn.
