The 1.7.10 pack - automatic smeltery

[LasieCZ]

Hey guys,

I just build this starting smeltery from TiCo using Thermal Dynamics but sometimes there remains nuggests after the smelting ends. Anybody some TIPS how to get them out without destroying every single casting table? 

Thanks much. I will be glad for every answer
