When I first bought my car. My fuse block had a fuse on the far right side if I remember correctly. Where it was, is not important. This fuse was different in that it had what appears to be a thick white cardboard on the inside. Making it not see through like the others. I’ve seen this before, but it’s been an extremely long time. My question is, why is this fuse designed this way and not clear like we are used to seeing ? And does that type have to be used, if infact it was originally designed to be different compared to the others ?
 
I think I've seen fuses like that before, but I "think" it was just a particular brand of fuse and I don't think they were original like that (I could be wrong). In any event, there is nothing "special" about it and you can use the standard parts-store AGC type fuses.

Yeah Purple, that was my thoughts too. It just doesn’t make sense to me. I think there’s a logical reason for it. Could be wrong. I think they used to design the larger amp ones this way. It’s 20. I think it’s not clear. Because 20, 25 and 30 doesn’t blow as easily or often. Not needing to be clear.

Unless it is a slo-blow model it will not matter. Some fuses back then had a current limiting effect for larger short circuits. They would not have a glass tube, but instead an insulation material to handle the small arc that occurs when it blows. They were probably considered overkill for the vehicle application and went to the glass tube long ago. Usually, it would be the larger fuse amperages that would not be glass.

If you go far enough back, some of those fuses were filled with sand to help extinguish the arc. Glass would be useless in that case.
