comparing conventional Vents and Vent BlocksUltimate Vent Blocks allow for more efficient Venting than conVentional Vents. not only is more air eVacUated and risk of flash redUced, BUt the Vent rUnners that tie the Ultimate Vent Block to the die caVity insert also do not oXidiZe dUring remelt as seVerely as conVentional Vents. this allows the caster to reclaim more casting alloy.
