Casting around for something to fill the swimming pools on the Canberra, I thought I had a suitable clear cast resin - Tiranti's "GP" Polyester Resin.
I thought I'd better experiment a little before working on the ship and I'm glad I did.
Once the correct catalyst had been found, I mixed up enough to fill a bottle cap. This was carried out in the garage because the stuff stinks. A lack of planning meant I didn't have anything to set in the resin but felt encasing something would be more interesting than just pouring it.
The only thing to hand was a dirty cotton bud from the spray booth. Needs must so I loped the end off and dropped it into the resin. Think bug encased in amber a la Jurassic Park.
Once set, I peeled the cap apart and you can see the result. It's clear-ish. Certainly no use for high class swimming pools. Maybe if it were a municipal baths full of mucky school kids...
Could the discolouration be due to the dirty cotton bud contaminating the resin?
ReplyDeleteI don't think so. The bud was very dry and only dropped in at the last minute so I'd expect the discolouration to be localised if this were the case. I think I just have the wrong resin for this particular job.
