The iron fence is up and on the ReStore. According to the oldest person in the neighborhood, this fence has been standing for over 100 years. The iron is still solid and sound and would be a great garden or yard décor item. Plenty of life left in it, If taken care of, this will last another 100 years. Stop by and check it out, the total length of the three sections is 12 feet.

I had the opportunity to go out and look at a deck that was damaged by fire today, for the purposes of fixing it. This deck was constructed of a treated wood frame and a composite shell. What is "composite" anyway? It is a combination of recycled wood, dust or fibers, and a plastic or some kind, like PVC. When I thought of "composite", I knew it was a recycled product and normally maintenance free, that's part of the draw. I thought that this product was somewhat superior to wood, it ought to be for the price. After looking at the deck today, I'm not so sure. The fire started on an outside corner and spread to the entire underside of the deck, driven by wind. All of the joists were burnt and the flooring charred. Though the top of the decking wasn't affected, I'm not sure of the structural integrity of it after being burned on the bottom and subjected to intense heat. This got me wondering what the fire rating of composite decking was. After some research most of the decking available locally has a fire rating of "C". That is the same as wood, but unlike wood this has a plastic in it. A plastic fire seems to be a little harder to put out and not to mention the smoke and toxic fumes released when burned. The house the deck is attached to definitely has smoke damage from the burning composite. My hope is that others would not falsely assume that because this product is a "composite" that it is somehow more fire resistant than regular wood. The ease of use and low maintenance make this a good product, but the same care should be taken as with traditional materials and the cost of replacement taken into consideration.
Coming soon: Antique iron fence, over 12 linear feet. Watch the Re store for pics and purchase info.
Well the wood blanks or chunks that I have are Spalted Maple. Spalted because of the markings in the wood. This is sought after for its unique markings and if you look it up online, it's pricey stuff to get. I have several hundred pounds and if anyone is interested in it please let me know. Here is some info from spaltedmaplelumber.com
Spalting Spalting is any form of wood coloration caused by fungi. Although primarily found in dead trees, it can also occur under stressed tree conditions or even in living trees. There are four distinct types of spalting. However, only three of them are actually considered pleasing. Contents 1 Types 1.1 Pigmentation 1.2 White Rot 1.3 Zone Lines 2 Conditions 3 Commonly Spalted Woods 4 Common Spalting Fungi 5 Spalting Research 6 References Types Spalting is divided into three main types: pigmentation, white rot and zone lines. Spalted wood may exhibit one or all of these types in varying degrees. Pigmentation Also known as sapstain, or in its most common form, bluestain, this type of spalting occurs when the darkly-pigmented fungal hyphae grow in the sapwood parenchyma of a tree [1][2]. A visible color change can be seen if enough hyphae are concentrated in an area [3]. These pigmentation fungi often colonize wood via the rays, but are not considered decay fungi due to their non-destructive use of easily available wood carbohydrates [4][5]. The most common groups of pigmentation fungi are the imperfect fungi and the Ascomycetes [5]. Mold fungi, such as Trichoderma spp., are not considered to be spalting fungi, as their hyphae do not colonize the wood internally. While pigmentation fungi do not degrade the wood cell wall, this type of decay can lead to a reduction in toughness (amount of energy absorbed before breaking), and increased permeability [6]. Pigmentation can occur on both hardwood and softwood, unlike other types of spalting which are more host specific. White Rot The mottled white pockets and bleaching effect seen in spalted wood is due to white rot fungi. Primarily found on hardwoods, these fungi 'bleach' by consuming lignin, which is the slightly pigmented area of a wood cell wall [7]. Some white rotting can also be caused by an effect similar to pigmentation, in which the white hyphae of a fungus, such as Trametes versicolor (Fr.) Pil., is so concentrated in an area that a visual effect is created [8]. Both strength and weight loss occur with white rot decay, causing the 'punky' area often referred to by woodworkers. Brown rots, the 'unpleasing' type of spalting, affect these same properties, but at a much faster rate [3]. Both types of rot, if left uncontrolled, will turn wood useless. Zone Lines Dark dotting, winding lines and thin streaks of red, brown and black are known as zone lines. This type of spalting does not occur due to any specific type of fungus, but is instead an interaction zone in which different fungi have erected barriers to protect their resources [5]. The lines are often clumps of hard, dark mycelium, referred to as pseudosclerotial plate formation [9]. Zone lines themselves do not damage the wood. However, the fungi responsible for creating them often do. Conditions Conditions required for spalting are the same as the conditions required for fungal growth: fixed nitrogen, micronutrients, water, warm temperatures and oxygen [10][3]. Water: Wood must be saturated to a 20% moisture content or higher for fungal colonization to occur. However wood placed underwater lacks sufficient oxygen, and colonization cannot occur [6]. Temperature: The majority of fungi prefer warm temperatures between 10 and 40°C [6], with rapid growth occurring between 20 and 32°C. [11] Oxygen: Fungi do not require much oxygen, but conditions such as waterlogging will inhibit growth [12] [13]. Time: Different fungi require different amounts of time to colonize wood. Research conducted on some common spalting fungi found that Trametes versicolor, when paired with Bjerkandera adusta, took 8 weeks to spalt 1.5" cubes of Acer saccharum.[14] Colonization continued to progress after this time period, but the structural integrity of the wood was compromised. The same study also found that Polyporus brumalis, when paired with Trametes versicolor, required 10 weeks to spalt the same size cubes. Commonly Spalted Woods The Ohio DNR found that pale hardwoods had the best ability to spalt . Some common trees in this category include maple (Acer spp.), birch (Betula spp.) and beech (Fagus spp.). Common Spalting Fungi One of the more tricky aspects to spalting is that some fungi cannot colonize wood alone; they require other fungi to have gone before them to create more favorable conditions. Fungi progress in waves of primary and secondary colonizers [2], where primary colonizers initially capture and control resources, change the pH of the wood and its structure, and then must defend against secondary colonizers that then have the ability to colonize the substrate [2] [16]. Ceratocystis spp. (Ascomycetes) contains the most common blue stain fungi [17]. Trametes versicolor, (Basidiomycetes) is found all over the world and is a quick and efficient white rot of hardwoods [2]. Xylaria polymorpha (Pers. ex Mer.) Grev. (Ascomycetes) has been known to bleach wood, but is unique in that it is one of the few fungi that will erect zone lines without any antagonism from other fungi [18]. Spalting Research Initial lab work was conducted on spalting in the 1980s at Brigham Young University. A method for improving machinability in spalted wood using methyl methacrylate was developed in 1982 [19], and several white rot fungi responsible for zone line formation were identified in 1987 [20]. Current research at Michigan Technological University has identified specific time periods at which certain spalting fungi will interact, and how long it takes for said fungi to render the wood useless [14]. Researchers from this university also developed a test for evaluating the machinability of spalted wood using a universal test machine[21]. References ^ Corbett, N.H. (1975).

Using what little bark was left on it, I belive it is either maple or ash. Very unique, cool looking wood, very rustic. All of the colors and patterns are as they occured in the tree. I have this up on the ReStore. This would be good for wood workers to make bowls or tables or seats, will clean up very well! The bigger chunks are 100+ lbs. Let me know if you are intersted. Awesome project material!
