It is made of hardwood with great life and durability. This is a premium quality block so it will last 3 to 5 times as long. It also has better heat retention: great for platinum. \u003cbr\u003e\u003cbr\u003eThis chemically prepared charcoal block will glow under a flame and reflect heat back onto the work. It is a denser charcoal block but still soft so sticking in positioning pins to hold work in place will be easy. \u003cbr\u003e\u003cbr\u003eCharcoal solder blocks are very useful in the soldering process:\u003cbr\u003e* They don't absorb much heat. Instead they reflect it back helping to heat up pieces on it much faster.\u003cbr\u003e* They create a reducing atmosphere that consumes the oxygen around the piece being soldered. This helps to prevent fire scale.\u003cbr\u003e* Their surfaces can be sanded down if they get too worn.\u003cbr\u003e* If they are broken, the pieces can still be used.\u003cbr\u003e\u003cbr\u003eThere are a few drawbacks too:\u003cbr\u003e* They can crack or break after heating.\u003cbr\u003e* They can keep burning after the soldering is done.\u003cbr\u003e* They can be messy.\u003cbr\u003e* They can give off fumes, so use in a ventilated area.\u003cbr\u003e* They get used up. \u003cbr\u003e\u003cbr\u003eTypes available:\u003cbr\u003eSO487 = Standard 3-1\/2'' x 2-3\/8'' x 1-1\/4\"\u003cbr\u003eSO480 = Standard 5-1\/2\" x 2-3\/4\" x 1-1\/4\"\u003cbr\u003eSO482 = Hard 5-1\/2\" x 2-3\/4\" x 1-1\/4\"\u003cbr\u003eSO489 = Standard 7\" x 5\" x 1-1\/4\"\u003cbr\u003e\u003cbr\u003e* The hard premium charcoal block is super compressed with a durable, hard surface that reflects heat back for faster and cleaner soldering.\u003c\/p\u003e","brand":"FDJtool","offers":[{"title":"3-1\/2\" x 2-3\/8\"","offer_id":51210518364445,"sku":"SO487","price":14.95,"currency_code":"USD","in_stock":true},{"title":"5-1\/2\" x 2-7\/8\"","offer_id":51210518397213,"sku":"SO480","price":16.75,"currency_code":"USD","in_stock":true},{"title":"5-1\/2\" x 2-7\/8\" Hard","offer_id":51210518429981,"sku":"SO482","price":16.75,"currency_code":"USD","in_stock":true},{"title":"7\" x 5\"","offer_id":51210518462749,"sku":"SO489","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/1044\/0733\/files\/so480_L1.jpg?v=1781405634","url":"https:\/\/fdjtool.com\/products\/so480","provider":"FDJtool","version":"1.0","type":"link"}
