The native birch<em>(Betula alba<\/em>) is used as well as the bog birch<em>(B. pubenscens<\/em>) or the Nordic birch (<em>B. pendula var. karelica<\/em>). The species are distributed throughout northern, central and eastern Europe.<\/p>\n<h5>Wooden picture:<\/h5>\n<p>All woods of the Betula genus are characterized by a uniform structure and medium-fine pores. The sapwood and the outer part of the heartwood is white to light brown, the late wood zones, similar to sycamore maple, have a subtle yellowish brown color. In the core area, some types of wood are rather dark, i.e. brown or gray-brown in color, depending on the location. Overall, a rather plain, partly decorative wood with a natural, silky sheen (wavy grain). Exceptions to this are woods with growth anomalies (stunted growth, burl, intergrowth due to frost, insect infestation or genetic influences).<\/p>\n<h5>Properties:<\/h5>\n<p>The specific weight of European birch of the medium density class is given as approx. 0.65 <sup>t\/m3<\/sup> at a wood moisture content of 12%. Comparable to sycamore maple in terms of processing and drying. The stamina is only satisfactory. The shrinkage from fiber saturation to u=12% is 5.0% radial and 8.0% tangential. Birch is an elastic wood; the E-modulus is 16,500 <sup>N\/mm2<\/sup>. Depending on where it grows, the Brinell hardness is given as 23-32. The wood is easy to work with all tools and produces smooth surfaces. Wood is sensitive to fungi and is not durable.<\/p>\n<h5>Use:<\/h5>\n<p>Furniture making, turnery, knife handles, veneers, musical instrument making<\/p>\n<p>&nbsp;<\/p>\n<table border=\"0\">\n<tbody>\n<tr valign=\"top\">\n<td><strong>Sources:<br \/>\n<\/strong><\/td>\n<td>Wood Information Service (1987), leaflet series on wood species, sheet no. 93<br \/>\nditto (1998) Domestic timber and its use<br \/>\nWAGENF\u00fcHR (1996) Wood atlas<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<div><strong>Note: according to the latest findings, but excluding any liability<\/strong><\/div>\n<div>\n<h4>Curly birch, untrimmed \/ Karelian curly birch \/ curly birch<\/h4>\n<hr>\n<\/div>\n<p>&nbsp;<\/p>\n<div class=\"page-header\">\n<h5>BIRCH BURL KARELIAN<\/h5>\n<p><a href=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_32_500.jpg\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-medium wp-image-16736\" src=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_32_500-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\"><\/a> <a href=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_36_500.jpg\"><img decoding=\"async\" class=\"alignnone size-medium wp-image-16737\" src=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_36_500-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\"><\/a> <a href=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_27_500.jpg\"><img decoding=\"async\" class=\"alignnone size-medium wp-image-16738\" src=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_27_500-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\"><\/a> <a href=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_26_500.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-16739\" src=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_26_500-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\"><\/a> <a href=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_31_500.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-16740\" src=\"https:\/\/espen.de\/wp-content\/uploads\/2022\/12\/BirkeMaser_31_500-225x300.jpg\" alt=\"\" width=\"225\" height=\"300\"><\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<h3>Use<\/h3>\n<p>Furniture making, turnery, knife handles, veneers, musical instrument making.<\/p>\n<h3>Origin<\/h3>\n<p>Northern, Central and Eastern Europe<\/p>\n<h3>Properties<\/h3>\n<p>Elastic wood, easy to work with all tools, smooth surfaces are produced.<\/p>\n<h3>Certification<\/h3>\n<p>Cites I<\/p>\n<div>[su_button url=\"https:\/\/shop.espen.de\/de\/Drechselholz\/Holz-fuer-Billardqueues\/billardqueue-karelische-maserbirke-select-40-x-40-x-600mm.html\" target=\"blank\" style=\"flat\" background=\"#AFCA0B\"]View in the store[\/su_button]<\/div>\n","protected":false},"featured_media":17743,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_cat":[314],"product_tag":[],"class_list":{"0":"post-18604","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-wood","7":"pa_eigenschaften-flexible","8":"pa_herkunft-central-europe","9":"pa_herkunft-eastern-europe","10":"pa_herkunft-northern-europe","11":"pa_verwendung-furniture-construction","12":"pa_verwendung-tonewood","13":"pa_verwendung-turned-wood","16":"first","17":"instock","18":"shipping-taxable","19":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Birch, European - Espen AG<\/title>\n<meta name=\"description\" content=\"Holz f\u00fcr Musikinstrumente: Gitarre, Violine, Blasinstrumente.
