Top gathering electric furnace door

The ideal situation is to have your door and maintenance lid close with no space between.
So how bad is a little space? Say 1/8. Thinking about laying a thin layer of fiber In the space.

Since there is no outgas from electric, the goal is to stay airtight as much as ossible or it costs fuel.

That being said, outgas from your cullet may be an issue requiring venting. I don't know how you handle that.

I think Charles F had a small plug he used to vent then he would plug it up.
I never had to vent with my small pot. I was more concerned about loosing heat.

The other thing you've got to watch out for is drippage. Most top gather pots don't retain enough heat to get the gather to trail off and you end up with a bunch of glass around the port that can easily glue your door shut.

If your glass has any boric you'll definitely need to vent or it will find a way out itself.

The Mark Lauckner wire melter construction DVD describes an ideal configuration for what you are trying to accomplish, including features that will prevent an air gap from forming in the event that your crucibles settles a bit on a pile of grog, etc. Definitely seems like it might be more resistant to glass attack from gathering, compared to what I am seeing in your photo so far.
