{"product_id":"natural-charcoal-blocks-soldering-hardwood","title":"Natural Charcoal Blocks","description":"\u003cp\u003eThese soft natural charcoal blocks are made from solid, knot-free hardwood and specially treated to help prolong their working life. Charcoal blocks create a reducing atmosphere during soldering and reflect heat back onto the piece being worked, making the flame more effective and efficient. The soft composition readily accepts pins to hold items in place while you work, and wrapping the block with binding wire helps it maintain its shape through repeated use.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMade from solid, knot-free hardwood\u003c\/li\u003e\n\u003cli\u003eSpecially treated to extend working life\u003c\/li\u003e\n\u003cli\u003eCreates a reducing atmosphere to protect metal during soldering\u003c\/li\u003e\n\u003cli\u003eReflects heat back onto the workpiece for more effective flame use\u003c\/li\u003e\n\u003cli\u003eSoft composition accepts pins for securing work in place\u003c\/li\u003e\n\u003cli\u003eWrap with binding wire to help the block hold its shape\u003c\/li\u003e\n\u003cli\u003eAvailable in three sizes to suit a range of soldering tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eSolid knot-free hardwood, specially treated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eThickness (all sizes)\u003c\/th\u003e\n\u003ctd\u003e1-1\/2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProp 65\u003c\/th\u003e\n\u003ctd\u003eWarning: Wood Dust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eDimensions (L × W × H)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.152\u003c\/td\u003e\n\u003ctd\u003eSmall\u003c\/td\u003e\n\u003ctd\u003e3-1\/2\" × 2-1\/4\" × 1-1\/2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.162\u003c\/td\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003ctd\u003e4-3\/4\" × 3\" × 1-1\/2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e154.172\u003c\/td\u003e\n\u003ctd\u003eLarge\u003c\/td\u003e\n\u003ctd\u003e7\" × 4\" × 1-1\/2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMoisture Warning:\u003c\/strong\u003e Charcoal naturally absorbs moisture from the air. A block stored in a humid environment—near the ocean or in an area with seasonal humidity—can crack when high heat is applied as that trapped moisture escapes. Before first use, and any time the block has been exposed to humidity, follow this moisture-removal process:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eGently heat a cast iron pan or similar heavy pan on a stove burner.\u003c\/li\u003e\n\u003cli\u003ePlace the charcoal block in the pan.\u003c\/li\u003e\n\u003cli\u003eObserve the block for escaping steam until steaming stops.\u003c\/li\u003e\n\u003cli\u003eThe block is now dry and ready for use.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eBefore use:\u003c\/strong\u003e Charcoal blocks must be wrapped with binding wire and heat cured before use.
