Experimental, "One of a Kind", and "Factory Second" Sculptures


We have a limited number of specimens that are less than perfect, are one-of-a-kind or experimental specimens, or are leftovers of styles that we've discontinued. Some may have small dings along an edge that can often be removed with a bit of lightly sanding and polishing. Some may have a small (~1/2" or less) fracture in the area where the discharge exits the sculpture, or a small surface scratch that can be manually buffed out with a little work. The base discharge fractures can often be hidden by simply inserting the specimens into one of our lighted bases. Other sculptures may have heavier discharges that have a darkened or more fractured appearance, especially near the main discharge "roots". Although this makes these specimens somewhat less attractive when not illuminated, these sculptures are often more fascinating than our regular ones since they typically contain very unique patterns and a combination of chaotic or densely dendritic ("moss agate") discharges. They are especially attractive when edge-illuminated by Light Emitting Diodes( LED's), as the light is reflected and refracted off the fractures that make up the Lichtenberg figure. The thickest discharges often look almost crystalline. For specimens with multiple charge layers, beautiful star burst (or snowflake-like) discharges may also occur. For example, see "Heavy Weather" specimens (such as Styles 16 or 25), where a combination of "snowflake" and chaotic discharges often occur. An image of a Style 16 "Heavy Weather" specimen that can be manually rotated can be seen here. Others merely need a bit of loving care, some elbow grease, and a touch of Novus Plastic Polish to bring them back to their full beauty. Periodically, we may also list first-quality trial specimens from some of our experimental tests.

Discharge "Types":
Some Factory 2nd sculptures may be available with a variety of discharge types. Discharge types vary depending on how much charge we injected and how, and when, we discharged the specimens. Following are some images that illustrate some of the more common types of discharges. The exit point of the discharge may be along an edge (edge discharge) or somewhere inside one of the large surfaces (interior discharge). In addition, the structure of the discharges may be branching and tree-like (Dendritic), lightly branched (more lightning-like), densely branched or fern-like (Bushy Dendritic), a random tangle of discharges (Chaotic), or a mixture of Dendritic, Bushy and Chaotic discharges (Mixed). The following examples should help clarify these - click on images below to see larger images:

These specimens are priced at 50% (or more) off regular prices. Not all of our sculpture styles have "seconds", and many styles may only have one or two factory 2nd specimens. Currently available "factory seconds" are shown below - we update this page to reflect our current inventory. Please remember that we may only have a small number of specimens in any given style. Sorry - no quantity discounts, but we do combine shipping on multiple items. These are offered on a first-come first-served basis, so order now to avoid disappointment.  

Sorry, no individual photos are available - we guarantee you will be satisfied or your money back.


International Customers - Please Note:
Please review our Ordering Instructions BEFORE completing your order. If your order is shipping outside the USA, please make sure to select an international shipping option to avoid processing delays or cancellation of your order. We offer three international shipping options that allow you to balance your expected delivery needs versus shipping costs. Please note that some countries impose additional local taxes and fees (for VAT, tariffs, or local postal service charges). These are the responsibility of the buyer. Large specimens may require additional shipping cost because of their larger size and weight.




Style 05 Factory 2nds

Masked example

Style 5: 4 x 4 x 3/4" Factory 2nd
Sorry - out of stock

These are approximately 4" x 4" x 3/4" factory 2nd sculptures - our most popular size. Factory 2nds may have dendritic, mixed dendritic and chaotic, or fully chaotic discharges. Some have various experimental masked shapes (log spiral, heart, disk(s), male and female symbols, etc.) with positive or negative 2D shapes. Some sculptures may have a small chip or fracture where the discharge exited the sculpture - this will be hidden when the specimen is inserted into one of our light bases. Other specimens have very small dings along the otherwise sharp edges. With a little bit of effort these can be sanded and polished away. Some have some extra discharging divots along the outside flat edges, while the acrylic in others show some radiation fogging which scatters light, causing the specimen to look slightly milky when brightly illuminated. Other specimens have one or two barely noticeable small (<1/16" dia. or less) surface imperfections on the large surface(s). Newer specimens have a slightly fluorescent solarization layer that glows with a greenish-yellow color when illuminated by "electric blue" LED's and, to a lesser extent, with white LED's. No matter the reason for these being 2nds, we guarantee that all 2nd's and experimental specimens are beautiful when edge-illuminated and that you will be delighted with your purchase.

All of these sculptures look absolutely beautiful when illuminated by our four inch wide natural walnut light bases (DK40x75 series, $66) or our black brushed aluminum bases (GSB1904L, $40). Walnut bases can be provided with a choice of cool white, natural white, or electric blue LED's. All of our aluminum bases come with cool white LED's.
Note: Light base is not included and must be ordered separately.

Style 05A - 4 x 4 x 1/2 inch sculpture

(Click on image for larger view)
Style 5A: 4 x 4 x 1/2" Experimental - $50
These are NOT factory 2nds. They are beautiful experimental specimens measuring approximately 4" x 4" x 1/2", similar to the sculpture at left (shown in a GSB1204L light base). These sculptures are similar to our thicker Style 5 sculptures except they are 1/2" thick instead of 3/4" thick. Otherwise, these are as every bit as beautiful as their thicker counterparts. Sculptures have either a single branching discharge originating from one edge (as shown in the image) or radiating outward from at, or near, the center. We recommend ordering a four-inch wide matching light base to safely hold and display the incredible detail and inner beauty of your sculpture.

The GSB1204L base has an elegant brushed satin black anodized aluminum finish, with cool white LED's, and comes with your choice of 120 volt North American/US, or 240 volt EC (Europlug), UK, or AU power adapter options.
Note: Light base is not included and must be ordered separately.

Style 7A: 6 x 6 x 1/2" Experimental - $80
Special: 20% discount vs our Style 7 sculptures!

These are NOT factory 2nds. They are large, beautiful experimental specimens measuring approximately 6" x 6", similar to the Style 7 (shown at left. but 1/2" thick versus the Style 7 (3/4" thick). Otherwise, these are every bit as beautiful as their thicker counterparts. Sculptures will have a single branching discharge originating from one edge, from the interior, or near a corner - our choice depending on our current inventory.

We recommend that customers also order a GSB1206L six-inch wide matching light base to safely hold and display the finest details and inner beauty of your sculpture. A few sculptures have slightly darker solarization (an amber-colored layer between the irradiated surface and the discharge layer) that normally fades over time. The solarization layer may also fluoresce with a light yellow-green color in some specimens.   The GSB1206L base has an elegant brushed satin black anodized aluminum finish, with cool white LED's, and comes with your choice of 120 volt North American/US, or 240 volt EC (Europlug), UK, or AU power adapter options.

Style 9, Factory 2nd

(Click on image for larger view)
Style 9A: 4 x 6 x 1/2" Factory 2nd - $42.50

Style 9A (approximately 4" x 6" x 1/2") specimens with dendritic, densely dendritic, or mixed dendritic and chaotic discharges. Specimens may have one or more edge or interior-based discharges. Some self-discharged specimens may show a bit of charring and heavier fracturing along the main discharge path(s). However, the charred regions virtually disappear when the specimens are illuminated by one of our LED light bases. Some specimens may have an extra divot or two where the specimen failed to discharge during the first try. Others have a small (1/4" - 1/2") fracture along an edge discharge point that will be hidden when the specimen is inserted into one of our lighted bases. A few specimens may also have matte-finish router-cut edges instead of highly polished edges, and a few may have small scratches or surface imperfections on the large area surfaces. Four-inch or six-inch wide bases can be ordered separately. We have high standards, so all of these factory 2nds still look beautiful when inserted and illuminated by one of our lighted bases. Your satisfaction is always guaranteed.

Note: Light base is NOT included and must be ordered separately.
The GSB1204L (4" wide) and GSB1206L (6" wide) aluminum bases have an elegant brushed black satin anodized finish, with cool white LED's, and come with your choice of 120 volt North American/US, or 240 volt EC (Europlug), UK, or AU power adapter options.

Prism with Two Discharge Layers

These sculptures were irradiated on one side, flipped 180 degrees, and irradiated again to create two independent charge layers, each located about 1/2" below the largest surfaces. All have dendritic discharges. Two discharge types ("parallel planes" and "windblown lightning") originate from the edges, similar to the left specimen in the top image. The remaining discharge type is an "African Tree" (kind of similar to an acacia tree). The discharge originates from the center of one of the large faces and connects to one charge layer, then spreads upward to the second layer. Some sculptures may have light charring in the paths nearest to the discharge point, but this disappears when illuminated by an LED light base. The lower image shows the two discharge layers and typical appearance from the side. From left to right are parallel planes, windblown lightning, and African tree. The sculptures in the images to the left were illuminated along the edges by blue and white LED's using a special light box so that we could quickly photograph them. These are representative examples of the specimens we have in stock - your sculptures may vary from those shown, but we guarantee that you will be delighted.

Recommended bases include the LM2688 rosewood light base with natural white LED's or our custom walnut DK25x75 base, available with cool white or electric blue LED's.

Now back in stock - while they last

These are cute little 2" x 1/2" thick disks with a laser-cut, flame-polished edge.
Most sculptures have one or more mixed chaotic/dendritic or dendritic (branching) discharges that have one or more roots within the interior or along the curved edge, similar to the specimens in the top row. Most have branching (dendritic) discharges that originate from an edge or from a point near the center of the interior, similar to those in the bottom row. A few may have an extra divot or two that we made while trying to discharge the specimens. The sculptures in the image to the left were illuminated along the edge by blue and white LED's using a special light box so that we could quickly photograph them. They're ideal as stocking stuffers, surprise gifts, marketing gifts, or small demonstration Lichtenberg figures for the math or science classroom.
