Petrified wood in the Haut-Rhin: a behind-the-scenes look at artisanal craftsmanship

In the Goldstein Créations workshop in Spechbach-le-Bas, in the Haut-Rhin, each piece crafted from petrified wood requires days of work, from studying the log to the final polish. Wondering why a one-of-a-kind piece takes so long? Because the material, harder than granite, dictates its own pace. Here’s a behind-the-scenes look at this artisanal process, step by step, with one stage that’s more critical than all the others.

How do you choose a piece of petrified wood before shaping it?

Each piece of petrified wood is examined for its grain, colors, and structure before a single cut is made. This assessment of the material determines everything else: the direction of the cut, the slices to be taken, and the piece’s future use.

The logs fell naturally about 225 million years ago, during the Late Triassic period. Your Sundgau artisan personally selects them from private lands near Petrified Forest National Park in Arizona before they arrive in the Haut-Rhin region. To understand this extraordinary material, you can read more about the formation of petrified wood or follow the journey of a creation, from Arizona to Spechbach-le-Bas.

What are the steps involved in creating a piece of furniture from fossilized wood?

Three main stages follow one another in the workshop: sawing, reshaping, and then polishing. Each proceeds at its own pace, dictated by the material:

Stage	Time taken in the workshop	Why it takes so long
Examining the log	Varies depending on the piece	Analyzing the grain, colors, and structure before deciding on the cut
Positioning and securing	Meticulous preparation	Improper securing during sawing can be disastrous for the piece
Sawing	6 to 8 hours depending on dimensions	The material is harder than granite; the blade advances slowly
Restructuring	Several sessions of experimentation and adjustment	Finding pieces whose grain and colors match
Polishing	3 to 7 days, depending on the dimensions	Bringing out the stone’s subtle shades requires successive passes

Why is sawing petrified wood the most delicate step?

Handling the log, both before and after sawing, involves the greatest risks: a failure to properly wedge or secure it can ruin the piece. Months of selection and preparation are then put on the line in just a few movements.

The sawing itself takes 6 to 8 hours, depending on the piece’s dimensions. The blade cuts through a mineral material that has become harder than granite, and each slice reveals a pattern that no one, not even the artisan, knows in advance. This decisive step takes place in the petrified wood furniture workshop near Altkirch.

What is the restructuring of a piece of fossilized wood?

Restructuring involves assembling pieces with matching grain patterns and colors to recreate a harmonious surface. It is the most unobtrusive step in the craft, and one of the most time-consuming.

Finding the right pieces takes time: the hues must complement each other, and the lines must flow seamlessly from one fragment to the next. This painstaking assembly process is why no two pieces are alike. It also paves the way for creating custom-made fossilized wood furniture, designed specifically for your interior and dimensions.

How long does it take to polish petrified wood?

Polishing a piece takes between 3 and 7 days, depending on its size. Pass after pass, the surface gains depth and the stone’s nuances emerge.

This slow process is the price of brilliance: the material’s hardness leaves no room for haste. The result is evident in the fossilized wood creations on display in the gallery: coffee tables, sinks, and decorative pieces. Visitors immediately notice this meticulous attention to detail:

Where can you find crafted petrified wood in France?

The pieces crafted in Spechbach-le-Bas, in the Haut-Rhin department, are on display in the gallery and shipped throughout France. You can view the pieces at the Sundgau workshop-gallery or at the L’Écho du Temps boutique, in the heart of Mulhouse’s historic center.

Seeing the material in person is still the best way to appreciate what all that hard work brings to it: the depth of its hues, the feel of the polished stone, and the piece’s presence in a space. Your fossilized wood specialist in the Haut-Rhin will then guide you from selecting your piece to delivery.

Frequently Asked Questions About Fossilized Wood Creations

Why does fossilized wood take longer to work with than granite?

It is harder than granite. Fossilized wood is crystallized silica, with a hardness of about 7 on the Mohs scale, while granite ranges from 6 to 7. Each cutting and finishing step therefore takes longer than with commonly worked stones. It is this mineral density that accounts for the 6 to 8 hours of sawing and the 3 to 7 days of polishing required in the workshop.

Is it possible to speed up the production of a piece of petrified wood furniture?

The artisanal pace cannot be rushed. The workshop’s equipment dictates its own tempo, and forcing the pace would put the piece at risk, particularly during handling. Patience has been part of the craft since 1993: petrified wood must be earned.

How should I care for a fossilized wood piece on a daily basis?

Simple care is all that’s needed. The mineral material is extremely durable and suitable for daily use, whether it’s a coffee table or a sink. The workshop will advise you on the proper care procedures when your piece is delivered.

Do you ship your creations anywhere in France?

Every creation is shipped anywhere in France. Support continues after your purchase, from packaging the piece to its installation, with follow-up provided directly by the Haut-Rhin workshop.

How do I start a custom furniture project with your artisan in the Haut-Rhin?

A phone call or a visit to the gallery is all it takes to get started. Call 03 89 07 06 82 or stop by the L’Écho du Temps boutique at 3 rue des Bouchers in Mulhouse with your measurements and a few photos of your interior: we’ll then work with you to bring your project to life.
