State and national labor laws about boilers and industrial furnaces explained in plain english.Hrlaws.Com.Flamethat is not a boilerwith a primary purpose of transferring heat indirectly to a process material or to a heat transfer material for use in a process unit instead of generating steam.Standards addressing direct transfer.
The heat-transfer process involves 1 latent heat transfer owing to vaporization of a small portion of the water and 2 sensible heat trans- fer owing to the difference in temperature of water and air.Approxi- mately 80 percent of this heat transfer is due to latent heat and 20 percent to sensible heat.

Im careful at this step, because the transfer can only be used once.If the piece is too wet, the underglaze will smudge.If its too dry, the bisqueware will suck the moisture from the paper and adhere it to the cup, which can pull the layers of underglaze off.Avoid spraying the piece after the transfer is applied as the stain will bleed.
