{"product_id":"european-compressed-charcoal-blocks-soldering-4-sizes","title":"European Compressed Charcoal Blocks","description":"\u003cp\u003eA compressed charcoal block gives you a soldering and annealing surface that reflects heat back into the work, so the torch flame does more of the job. These European blocks are imported from Poland and made of dense compressed charcoal, which makes them harder and heavier than standard soft charcoal blocks. Before use, wrap the sides tightly with binding wire and heat cure the block to prepare it properly. Annealing the block before first use will also extend its working life.\u003c\/p\u003e\u003cp\u003eCharcoal naturally absorbs moisture from the air. A block stored in a high-humidity environment can crack when high heat is applied, as trapped moisture tries to escape. Follow the preparation steps in the Notes below before first use or any time the block has been exposed to humidity.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDense compressed charcoal construction, harder and heavier than standard soft charcoal blocks\u003c\/li\u003e\n\u003cli\u003eReflects heat back into the work for efficient soldering and annealing\u003c\/li\u003e\n\u003cli\u003eImported from Poland\u003c\/li\u003e\n\u003cli\u003eAvailable in three rectangular sizes and one round size\u003c\/li\u003e\n\u003cli\u003eLonger lasting when annealed before first use\u003c\/li\u003e\n\u003cli\u003eMust be wrapped with binding wire and heat cured before use\u003c\/li\u003e\n\u003cli\u003eBlocks will shrink with use over time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eDimensions (inches)\u003c\/th\u003e\n\u003cth\u003eDimensions (mm)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.148\u003c\/td\u003e\n\u003ctd\u003eRound\u003c\/td\u003e\n\u003ctd\u003e5-7\/8\" diameter x 1-3\/16\" thick\u003c\/td\u003e\n\u003ctd\u003e150mm diameter x 30mm thick\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.149\u003c\/td\u003e\n\u003ctd\u003eSmall\u003c\/td\u003e\n\u003ctd\u003e3-3\/16\" L x 2-3\/8\" W x 1-3\/16\" H\u003c\/td\u003e\n\u003ctd\u003e80mm L x 60mm W x 30mm H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.150\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003ctd\u003e5-1\/2\" L x 2-3\/4\" W x 1-1\/4\" H\u003c\/td\u003e\n\u003ctd\u003e140mm L x 70mm W x 32mm H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.175\u003c\/td\u003e\n\u003ctd\u003eLarge\u003c\/td\u003e\n\u003ctd\u003e7-7\/8\" L x 5-1\/2\" W x 1-3\/16\" H\u003c\/td\u003e\n\u003ctd\u003e200mm L x 140mm W x 30mm H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBinding wire wrapping is required before use to help prevent cracking during heating.\u003c\/li\u003e\n\u003cli\u003eBlocks will shrink with repeated use, which is normal.\u003c\/li\u003e\n\u003cli\u003eStore charcoal blocks in a cool, dry place to minimize moisture absorption between uses.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eMoisture removal before first use:\u003c\/strong\u003e\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eGently heat a burner on your stove and warm a cast iron pan or similar heavy pan.\u003c\/li\u003e\n\u003cli\u003ePlace the charcoal block in the pan.\u003c\/li\u003e\n\u003cli\u003eObserve the block for escaping steam.\u003c\/li\u003e\n\u003cli\u003eOnce steaming stops, the moisture has been removed and the block is ready to prepare for use.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Otto Frei","offers":[{"title":"Small","offer_id":47551724323030,"sku":"154.149","price":16.95,"currency_code":"USD","in_stock":true},{"title":"Standard","offer_id":47551724355798,"sku":"154.150","price":23.95,"currency_code":"USD","in_stock":true},{"title":"Large","offer_id":47551724388566,"sku":"154.175","price":42.95,"currency_code":"USD","in_stock":true},{"title":"Round","offer_id":47551724421334,"sku":"154.148","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/european-compressed-charcoal-blocks-otto-frei.jpg?v=1719955449","url":"https:\/\/www.ottofrei.com\/ja\/products\/european-compressed-charcoal-blocks-soldering-4-sizes","provider":"Otto Frei","version":"1.0","type":"link"}
