Fire and Ice – Experiments with the Golden Crackle Paste

There are many products available that are not originally meant for the aspiring model terrain maker, but nevertheless provide us with the right tools to recreate nature. One of these products is the Golden Crackle Paste. Being an acrylic effect paste that – as the name suggests – cracks during the curing process, it supplies us with the perfect means to depict dried out lakebeds, but also cracked ice or even cracked lava.

In this short review I document the curing process over several days and show two of the terrain pieces I made using the crackle paste, namely an almost dry lake with barren trees and a water hole as well as  a frozen lake with cracked surface and a snow-covered tree.

Golden Crackle Paste – Properties

The paste has a very light, fluffy consistency that can be easily spread out on a surface with a spatula. The thicker the application, the deeper the cracks and fissures and the longer it will take for the paste to dry.

Golden does not recommend to add water, retarder or other additives, as this can ruin the effect. I applied the paste on a piece of sealed MDF and smoothed the surface out with a spatula. The thickness of application was 2mm.

The paste can be smoothed easily. It does not cling much to the spatula.

After 12 hours first cracks show.

24 hours later the cracks got bigger and some more, much finer cracks develop.

36 hours later the new fissures got wider as well.

After 48 hours the curing process is mostly finished. Some of the finer fissures did increase in size.

The cured paste adheres well to the sealed MDF, but on other materials such as polystyrene it needs a topcoat to fix it in place. I used thinned down acrylic medium, but PVA will do a good job, too. The surface is hard, yet brittle, so top coating it is in general a good idea. Even though the paste is fluffy when first applied it does shrink a fair bit and will thus withstand normal gaming use without problems.

The surface can now be painted with acrylic paint and washes to achieve the effect you are after.

The cracking process produces rather big floes and might thus not be very suitable for very small scales or if you are after smaller floes to depict a dry lake bed. Here other products provide a better result. Check out the Terranscapes review of a product called Kroma Crackle which produces a more mosaic like texture. It is possible to control the cracking to an extend, as a thinner application does seem to produce smaller floes, however, too thin and no cracks show at all. It is a good idea to make some test pieces first and see how the paste behaves on different surfaces. I strongly advise against any unsealed or absorbent surface, as this seems to soak up the paste and results in a thin, flaky layer (check out the Terranscapes clip to see this effect).

What can we do with it?

While it has its limitations I still see a number of uses for the Golden Crackle Paste. My first two attempts were a dry lake bed with some barren trees, tufts and a water hole as well as a frozen lake with a cracked surface and some ice floes.

The ramifications of the barren trees are this time made of copper wire covered with caulking.

For the snow I mixed Bicarbonate of Soda with Acrylic Gloss Gel.

Both pieces are fairly simple.While it is obvious that the crackle paste was used to depict the dry lake bed, the frozen lake uses the formation of floes to depict exactly those: After the paste is dry some floes are removed where water is supposed to be visible later on.

The procedure to make the trees follows more or less the method outlined in my oak tutorial. However, this time the finer ramifications are made of copper wire, not sea moss. They are thus very flexible and withstand quite a bit of handling. However, if one overdoes it the coating can crack, but one will never be able to rip a branch off, the copper wire is too strong. This is an advantage in comparison to sea moss and one can shape the branches to a certain extend. All big trees are magnetised and can be easily removed should there be the need.

Some life can still be found, but soon no water will remain.

The water effect in the water hole is simply several layers of Liquitex gloss varnish mixed with a brown wash and a hint of grey acrylic paint. You really need to apply several thin layers and make sure to pop any airbubbles to get an even surface. The snake in the background is from the trusty Busch Kleintierset. I painted it up as a typical desert snake with just enough colour difference to spot it.

Adding some of the snow mix to the branches adds realism.

While there are quite some good products available to depict snow, for this first attempt at making snow terrain I used the old bicarbonate of soda method. It is of importance that you use a glue or medium that contains no acidic components, as this seems to cause the bicarbonate to yellow with time. If you are worried add some white paint and as a final step seal your work with matte varnish. With this piece I used Golden acrylic gel gloss. For the Ice floes I used acrylic gel matte, to give the appearance of thick ice, which does not have a strong lustre. After you applied the paste sprinkle some more bicarbonate of soda on top. A very good product for snow effects are so called microballoons, a filler product for resin casting. I sourced a local supplier and will in some later point give that product a try.

Some of the smaller bushes can still survive, while the bigger trees are long dead.

I hope you enjoyed this short review of the Golden Crackle Paste and it inspires you to give it a try yourself. My old friend Khael was not really impressed, but he is a grumpy old dwarf.

Khael was cursing in his beard. It had been snowing for days, at least his pipe provided a bit of solace.

    1. Thank you for your comment! As alwasy much appreciated. I think it could also work very well for lava (my next experiment) and a bigger frozen lake that shows first fissures. The lakebed is alright as long as the cracks are not too big, but I feel something like Kroma Crackle is a better product for this.

    1. Thank you arkiegamer. Glad you like the vignettes, can’t stop including those ;). I think the paste with a topcoat of acrylic medium or PVA will hold up to heavy gaming use. I could see with extreme usage it might chip, but then I treat my terrain with care. If you let it drop to the floor it might crack, but I am not willing to try it :P.

      1. Oh, come on-throw your hard work at the floor, and walls, in the interest of science! What kind of reviewer are you?!

        I kid, of course.

        Good point about the PVA/acrylic medium. That stuff makes anything tough.

  1. Aww, such a grumpy old wizard 😉 Well, I guess that’s their prerogative, right? 😀 more OT: are you planning to do a lava terrain piece specifically? I’m sure with how great these pieces are you’d get an awesome result!

  2. Both turned out really nice using the crackle paste. I also really like the snow effects, something I’ve had problems pulling off convincingly in the past.

    1. Hi Brian, thank you for your comment. Always good to get feedback. What did you use for the snow in your attempts? I really look forward to use some so called microballoons,a s it seems to be the perfect product to depict snow.

      1. I tried a couple of different powders including Woodland Scenics snow but they were all disappointing. I’ll have to look into the microballoons as I’ve never heard of them before.

      2. Have a look at this wikipedia entry:

        http://en.wikipedia.org/wiki/Glass_microsphere

        Amongst other applications it seems to be used a s a filler to bulk out resin. A marine and yachting shop might have some. Some of the stuff comes in a tan/brown colour, some is off-white. I saw it being named Q-cel (which might be a slightly different product/mix) by West Systems. A 1l bag costs around 11 NZ Dollars, so very cheap in comparison to other snow products.
