Bluestone does not always need sealers though sometimes they are applied eg food areas just to make cleaning a little easier If bluestone is in a high risk area it pays to seal High traffic food preparation areas under trees dogs etc might all mean that 2 coasts of Sealers Choice Gold would be a good option to prevent staining We recommend that our bluestone be presealed prior to installing or

Vacuum degassing of steel takes place after the molten steel has left the furnace and before the steel is poured into ingots or processed through a caster The main objectives of steel degassing are Reduction or elimination of dissolved gases especially hydrogen and nitrogen Reduction of dissolved carbon for more ductile steel
