Purkije Boards achieve a wide palette with a range of effects through the use of pigment and aniline-dye stains. They are roughly as lightfast as stained hardwood is, using these coloring agents, with as much variability. Ultraviolet radiation from sunlight degenerates all synthetic pigments, to different degrees. We rate the colorfastness of each Purkinje Board finish from A+ to C-, with “A+” displaying the lightfastness of pigment-stained hardwood, and suitable for any application where that material would be used, and “C-” displaying the lightfastness of hardwood stained with alcohol-based aniline dye stains, and so only suitable for locations which will not be subject to direct sunlight.
160 distinct color treatments are currently available.
Purkinje Board is suitable for a wide range of applications, from furniture to paneling, cabinets to curio boxes, doors to display cases. Beta testing has begun on flooring and wet applications (such as bath vanities).

Purkinje Board is available is a wider range of dimensions than any other finished building and fabrication product. From 1/4” x 4’ x 10’, to 3-1/2” x 24” x (X)’ structural members (span tables are available on request), Purkinje Board can be made to fit almost any conventional need, and a whole lot of unconventional ones too.
Purkinje Board is finished in two-part catalyzed varnish suitable for commercial flooring applications and rated ÖNORM C 2354 Category C (Very Heavy Wear). Furnishings and cabinets first entered use in commercial spaces for beta testing in 2014. These and other pieces have been subjected to extensive wear and abrasion testing. It has been used in residential spaces since early 2016. It is highly durable, but it is also easily repairable, with patches blending easily in the variegated finish.
Purkinje Board is available in matte to semi-gloss, though cost increases approximately 15% for every sheen grade step above matte.
Purkinje Board is made using fast growing saplings and scrap materials from larger wood products. Recent research has shown that frequent harvests of these young trees enable greater conversion of CO2 into oxygen than older trees in longer cycle plantations. And in previous decades, the scraps were merely piled high and burned in mounds that smoldered for weeks. Sealer and topcoats are Greenguard certified and GEV-EMICODE classified EC1R for very low emissions and indoor air pollution.
Purkinje Board is fabricated using a painstaking process developed and honed over the better part of a decade. The product is mature, but the process is still developing, and economies of scale greatly influence pricing. In general, for small quantities of 50 sf or less, Purkinje Board should be considered to cost starting at $20 / sf in matte finish. Sheen, specific finish treatment, and a couple of other choices will influence this price somewhat as well, but quantity will be the most influential factor.
No nutria are harmed in the making of Purkinje Board. In fact, we are told by our nutria wranglers that these large aquatic and highly intelligent rodents appear to enjoy the weekly musk harvest.
