Is spalted wood valuable?

Although spalted wood is highly prized and sought-after by woodworkers, designers and architects, spalting is a form of decay and poses potential risks to the wood’s structural integrity, affecting weight and strength in particular.

What is spalted birch?

Spalting is caused by certain white-rot decay fungi growing in wood–primarily hardwoods such as maple, birch, and beech. The unusual coloration–black, pink, gray, and multicolored streaks–may result from reactions between the wood, the decay fungi, and insect deposits.

Is spalted wood weaker?

Like a piece of fruit that’s been infested with mold, spalted wood has a weaker structure than a wood that has not been eaten by a fungus, and if you wait too long for a cool pattern, you might end up with a wood that falls apart in your hands.

Is spalted maple rare?

Though rare and difficult to find, spalted maple, with its eye catching black wavy streaks, is in high demand, according to hardwood and veneer suppliers interviewed by Woodshop News. Spalted maple starts as a regular maple until decay causes a black marble pattern to form, making it anything but a commodity.

How do you finish spalted wood?

We recommend applying lacquer or water-based varnish, two finishes that add little color to wood. However, if you prefer a warmer, more amber look, you can use oil-based varnish or shellac. You might choose polyurethane for items that will receive a lot of use. Avoid applying oil, such as boiled linseed oil.

Can you turn spalted wood?

Turning is a great way to display spalted wood. You can turn dried blanks, but green wood has a more consistent density. If areas of the wood are spongy, or if there are small splotches of white throughout the piece, you might want to stabilize those areas with a two-part, five-minute epoxy resin or cyanoacrylate glue.

How do you stop wood from spalting?

I rough-turn my spalted bowl blanks first, then let them air dry for about a year to stop the fungal growth. After that, put your dust mask on and turn them like any other bowl.

Is it safe to burn spalted wood?

Can you burn spalted wood? Yes, it’s completely fine to burn spalted wood.

How do you seal spalted wood?

This is because it varies in density, a common problem with spalted wood. The solution is to spot-harden the spalted areas first, using a thin, penetrating cyanoacrylate (or “super”) glue. Use a medium-thickness glue for small gaps and a thick one for big gaps. After the glue has dried, sand the wood.

Why is spalted wood so expensive?

Spalted wood is not limited to only those who turn it on a lathe though. It can also be used on larger pieces such as table tops and even guitars. Prices for boards that are large enough for tables can get expensive due to the size and the scarcity factor of spalted wood in general. Is spalted wood dangerous?

Can spalting occur in softwood?

Spalting is most likely to occur in hardwoods, but can, if conditions are right, occur in softwoods as well. In order for spalting to occur within wood, there are three conditions that must be present in order for the fungi to grow properly.

What is spalting and how is it created?

It is created when white rot fungus begins growing within a piece of wood or log. When the fungus begins to grow withing the wood, the process is referred to as “spalting.” Spalting is most likely to occur in hardwoods, but can, if conditions are right, occur in softwoods as well.
