    Default Advice required for resin slab

    Hello all,
    I would like some advice on how to achieve the poured slab in the photo. I was thinking about 150mm x 100mm x 15mm the layers would not have to be even, can extra layers be added after the resin has cured, will the new layers stick to the cured ones?
    I am thinking of making some Jewellery cabochons as well as some pens.
    I have not used resin before, what would be the best material to use also what colouring medium?
    Any advice would be appreciated, Thank you.

    That second one actually looks like micarta, which is made with the addition of cloth layers in the pour.

    Both those slabs actually look more like someone has finally "gotten around" to scraping off the walls in an industrial spray booth.

    To replicate that in resin I'd simply mix minimal amounts, pour into a tray, slosh it around to get more or less even coverage and pour out the excess. Repeat ad-nauseum, alternating darker or more vivid colours with white/pastels.

    If I also wanted to replicate the "bumps & waves" I'd do the first pour (or two) slightly differently. Instead of getting even coverage I'd just pour small dobs at random intervals and let them settle. Subsequent coats will, in effect, magnify these lumps to give the wavy effect.

    I'd also probably be making several trays at a time with this method, to make it worth the effort. It should be a simple enough matter to calc how much resin would be needed per coat per tray, once you've measured the tray size(s) and decided on a depth of layer. 0.5mm?

    The last tray - in which the remnants are poured - would probably give the most interesting, randomised results.


    Having said all that, there's probably some much simpler way, (go clean a paint booth? ) but it eludes me.
    I may be weird, but I'm saving up to become eccentric.

    It could certainly be a long drawn out process , but one layer of PR poured at a different time will certainly bond to the previous ones , you don't have to wait till its set solid either ,after it has gelled but not quite hard you can make the next pour ,gently if you don't want a mix ,just different layers ,could be quite nice as cabochons
    good luck with it cheers ~ John
    G'day all !Enjoy your stay !!!
