Nice, and a good soundtrack for working there too

@111fishkiller- I will try to get some pouring videos uploaded soon.

@mmaaxx1198 - this is only done to burn the residual alcohol off so you don't have defects. It helps speed up the drying process. Rapid air movement can/should be used to help get the mold completely dry. It isn't done to add a carbon layer to the mold..

Is this like using an actylene torch to add a carbon layer to the sand when casting in glass?

[111fishkiller]

Any videos of the pour?

The alcohol has totally evaporated by lighting it but is the wash totally dry?

Some foundries use a fan afterwards to ensure dryness and prevent gas porosity?

Have you ever had porosity issues due to the wash being burned but not drying entirely? maybe at the transitions or corners? being that it is iron and it solidifies rather quickly, maybe not. I guess for iron you just have to make sure to clean the surfaces thoughly from any debrees which may cause voids.

Imagine burning off alcohol wash on "large" cores and molds. Fireballs can be pretty large.
