Food-Safe and Baby-Safe Wood Finishes Explained

Two questions come up more than any others in our inbox. "Are these food safe?" and "Can I use these for a teething ring?" The honest answer to both is that it depends entirely on what you put on the wood after it leaves our workshop.

Almost every part we make ships raw and untreated. No varnish, no oil, no wax, no stain. That is a deliberate choice, and this guide explains what it means for you, how the common finishes compare, and how to avoid the mistakes that catch out small makers. There is one exception in our catalogue, and we cover it further down.

Three Terms People Mix Up

Most of the confusion around this topic comes from three phrases being used as if they mean the same thing. They do not.

• Food-safe describes a finish that is safe to come into contact with food once it has fully cured.

• Food-grade describes the raw material itself, usually something like mineral oil produced to food industry purity standards.

• Toy-safe is a regulatory question, not a marketing one. In the EU the relevant standard for this topic is EN71-3.

Here is the part that surprises people. A finish can be genuinely food-safe and your finished toy can still fall outside EN71-3 compliance, because compliance applies to the finished article tested as a whole, not to any single ingredient in it.

EN71-3 in Plain Language

EN71-3 is the part of the European toy safety standard that deals with the migration of certain elements. It sets limits on how much of substances such as lead, cadmium, chromium and barium may transfer out of a toy if a child mouths or swallows part of it.

Three practical consequences follow from how the standard works:

• Testing is done on the finished product in the state it will be sold. The wood, the finish, any paint, any glue and any fabric are all part of what gets assessed.

• Responsibility sits with whoever places the product on the market, which is you as the maker or the brand, not the component supplier.

• A supplier cannot certify your product for you, because the supplier has no control over what you apply after delivery.

We supply the untreated component. What you do next determines compliance, and that is precisely why we leave the wood bare.

Common Finishes Compared

There is no single best finish. The right one depends on whether the item will be handled, mouthed, washed, or put near food. Here is how the usual options stack up.

If you take one thing from that table, make it this: read the ingredient list, not the product name. "Tung oil finish" and "pure tung oil" are frequently very different products sitting on the same shelf.

What to Avoid on Items for Babies

If the item will end up in a child's mouth, and with small children it will, these are the traps worth knowing about.

• Oils labelled "boiled" or "quick drying" without a full ingredient list. That speed usually comes from added metallic dryers.

• Vague safety claims. "Non-toxic when dry" carries no legal weight on its own unless it names a standard it was tested against.

• Generic wood stain. Stain is colourant plus a carrier, and it is rarely intended for prolonged skin or mouth contact.

• Rushing the cure. Dry to the touch is not the same as fully cured. Those are different chemical stages and they can be weeks apart.

• Layering products. Wax applied over an oil that has not cured can trap uncured material underneath indefinitely.

How to Finish Our Parts Properly

Our components arrive sanded and ready to work with. This sequence gets you a smooth result rather than a fuzzy one.

First, give them a wipe

Worth knowing before you start. We sand and polish in machines, in tumbling drums and on sanding wheels, which is what gives the parts their even, consistent surface. It also means a fine wood dust settles into the grain and into any drilled holes during the process. We remove what we can before packing, but on a batch of a few hundred small parts some of it always travels with the order.

This is normal and it is only sawdust from the same wood the part is made of. A wipe with a dry or lightly damp cloth clears it in seconds. Do it before you paint, oil or wax, because a finish applied over loose dust will trap it in the surface and feel gritty afterwards. For beads and rings, running them through your fingers with a cloth is enough. For parts with holes, a quick blow or a pipe cleaner does it.

The finishing sequence

1. Wipe with a damp cloth and let it dry fully. This clears any residual sanding dust and deliberately raises the grain.

2. Sand lightly at 240 grit or finer. You are knocking the raised fibres back down. Skipping this is the single most common reason a finished piece feels rough.

3. Remove every trace of dust. A tack cloth or a vacuum, not a dry brush that just redistributes it.

4. Apply thin coats. Thin coats cure properly all the way through. Thick coats stay soft underneath and stay soft for a long time.

5. Respect the full cure time on the label, not the time it takes to stop feeling tacky.

6. For anything a child will mouth, cure warm, ventilated, and longer than the stated minimum. There is no downside to waiting.

Why We Ship the Wood Bare

It would be easy for us to oil everything before it leaves the workshop. We deliberately do not, for three reasons.

First, you keep control of compliance. If you are selling into the EU toy market, you need to know exactly what is on the surface of your product. A finish applied by someone else, in another country, to an unknown specification, is a liability you cannot document.

Second, finishes are project specific. A macrame bead, a teething ring and a cabinet knob want three different surfaces. Anything we chose would be wrong for most of our customers.

Third, raw wood accepts everything. Paint, stain, dye, ink, wax, oil, pyrography. Once a surface has been sealed, most of those options are closed to you or need sanding back first.

Everything we turn is solid European birch, oak, ash, pine or walnut, sanded smooth and hand checked, with nothing added. If you want the deeper technical side of specifying parts for production runs, our guide to choosing wooden components for serial production covers tolerances, batch consistency and lead times.

The one exception in our catalogue

There is a single product we supply already finished: the 44 mm oak wood napkin ring with a linseed oil finish. It is a finished table item rather than a component, so it is sold ready to use rather than ready to work on.

The oil is applied in our workshop and fully cured before the rings are packed, which brings out the grain in the oak and gives a soft natural sheen. If you would prefer that same ring bare so you can finish it your own way, just ask us and we will supply it unfinished.

Where to Start

The parts our customers most often finish themselves:

• Wooden beads for jewellery, macrame and garlands, where a pure beeswax finish is the usual choice.

• Wooden craft rings for teethers and mobiles, typically left raw or waxed.

• Wooden peg dolls for Waldorf and Montessori play, usually painted then sealed.

• Sanded wood balls in sizes from 8 mm to 60 mm.

• Kitchen utensil parts where food-grade mineral oil is the standard answer.

Important. Baltic Woodcrafts supplies unfinished, untreated wooden components, with the single exception of the oiled oak napkin ring described above. We do not certify finished products. Responsibility for the safety and regulatory compliance of a finished article, including EN71-3 testing where it applies, rests with the manufacturer or brand placing that article on the market.
