Frequently asked questions

What is Jesmonite?

Jesmonite is a water-based, non-toxic casting material made from natural derivatives, so unlike resin it's safe to handle. You mix the powder and liquid, pour the mix into a mould, and it sets hard with a smooth, stone-like finish. For the speckled terrazzo look, you make your own coloured chips with the pigments and add them to your pour.

What will I need from home?

Digital scales, a protective sheet (a bin liner works), a bowl of water and some baking paper for making the chips. Everything else, including gloves, cups, mixing sticks and sandpaper, is in the kit.

How long does it take?

Allow 3 to 4 hours in total, including making your terrazzo chips. Each piece needs 40 to 60 minutes in the mould, a little less on a hot day and a little more on a cold one. Then sand it and leave it for 24 hours to fully set. Sanding takes 5 to 10 minutes for shells and face pots, and up to an hour for coasters, trays and tealights if you want the chips to really show.

How many pieces can I make?

Up to 9, depending on your mould: 5 hexagonal and 4 round coasters, up to 8 shells, up to 4 face pots, or 3 trays and 3 tealight holders (the tray kit has one tray mould and a mould for three tealights). The moulds are reusable, so you can keep making with a Jesmonite refill.

Do the terrazzo chips come in the kit?

No. You make them yourself from the Jesmonite and pigments in the kit, and the guide shows you how.

Is it suitable for children and during pregnancy?

The materials are non-toxic and made from natural derivatives, so they're safe to handle and suitable during pregnancy. The kit isn't a toy, though: children aged 14 and under should be supervised by an adult, as some tools have sharp edges. Don't eat the materials, avoid breathing in the dust, and work in a well-ventilated space.

Can I use my pieces for food or drink?

We don't recommend it. Unsealed Jesmonite isn't waterproof and can absorb moisture and food debris. Your pieces are perfect for jewellery, keys and plants, and they work as candle holders: tealights go in the holders, and candles can stand on the coasters or tray.

Do I need to seal my piece?

It's optional, but sealing brings out the colours and adds some water resistance. Buff in a little coconut oil or beeswax with a soft, lint-free cloth, or use a clear varnish for a high-gloss finish.

How do I look after my mould?

Wash it in warm soapy water and it's ready to use again. An unopened kit lasts 9 months, and opened pigments are good for 9 months.

Is it a good gift?

Yes, in two ways. Give the kit to someone who'd love a new hobby, or use it to make a handmade set for someone special. Any leftover mix can become a little something for you.

Do you do gift wrapping?

Yes. We offer handwritten cards and gift wrapping options on all of our kits. Add your kit to the cart and click "Make it a gift" to choose your wrapping and write your message.
