Hi! It’s Heather from Thicketworks – and today I’m going to show you how you can use slush casting to create beautiful home decor accents with a minimum of time and material! I’ll demonstrate how you can use one of these really cheap plastic molds intended for plaster of Paris to cast beautiful architectural embellishments you can add right on top of metal items that have been treated with fire patina.
We’ll be working with a quick cure two-part resin today so grab your protective gloves and let’s get ready! I’ll be working with Fast Cast which as you can see, sets up in ten minutes! Because this mold is fairly elaborate, I’m going to add a mold release in the form of the simplest of materials – and that’s baby oil.
.. applied with a baby wipe. Doesn’t take much – just get some on to your cloth or your baby wipe and make sure to place it into all of the nooks and crannies of the mold cavity. Fast Cast quick cure resin comes in a bottle marked Part A and a bottle marked Part B: these are mixed together in equal amounts to create a resin mixture that sets up really quickly.
I’ll be adding this Alumilite black dye to the Part A portion of the mixture before blending them together. Now I’m not measuring here: I’m just giving a pretty decent squeeze of that black dye into the Part A and I’ll blend that together before we combine Part A and Part B.
The resin typically will dry to an almost ivory color so the addition of the black dye will create a lovely deep rich charcoal gray – and that charcoal gray is a perfect match to the background of our fire patina surfaces.
Once Part A and Part B of the resin have been added to the same container, you mix them thoroughly and carefully for 30 seconds – making sure to scrape the sides and the bottom of the container. Next, we’re going to pour the mixture into the mold and it will not fill the mold.
That’s the idea of a slush casting – we’re saving on the amount of material that typically would be used to fill a mold that’s this large. Every time we swirl the mixture around the interior of the mold we’re adding another fine layer of resin.
These layers build up slowly as you go through the slush casting method. As the chemical reaction begins to accelerate within the resin you’ll find that the mixture moves more and more slowly as you swirl it around.
It will continue to thicken during this process until it’s no longer possible for you to tilt the mold and have the resin move quickly. Once the resin is no longer in a liquid form and you’ve covered the entire interior of the mold, it’s time to set it aside for a few minutes: less than 10 – until the surface is no longer sticky to the touch.
At this point the resin has reached the “soft cure” stage and with a thin implement (like the tip of a craft blade) you can pry up one edge. Once you have that first edge free, you can then use the strength of your hands to pull the casting out of the mold.
Don’t worry if it tends to deform at this point: it will bounce right back to its original shape… and as you can see, it left the mold completely clear! At this point you can use a pair of scissors to clean up the edge of your casting.
Just a few snips to make sure everything’s nice and trimmed and this is ready to adhere to its substrate. I’ll be using the 3-in-1 glue by Beacon: this is a very strong craft glue and it works just as well as a 6,000 or Fabri Tack.
I’m applying it only to the areas that will come in contact with the surface of this fire patina tin – and then pressing it into place…verifying that it’s actually centered on that lid and then allowing it to cure for just a few minutes.
This looks amazing just “as is”, but I’d like to dress it up just a bit by adding a layer of Metallique “Old Silver” metallic wax to the high points. I love this wax as you probably already know, and it’s the perfect way to blend the charcoal of the casting into the metallic background of the fire patina tin.
It just takes a few swipes and a few moments and at the end of the process you have an heirloom worthy piece just like that in less than 20 minutes! Slush casting is one of the fastest and easiest ways to create stunning home decor items.
Thank you so much for hanging out with me today! Until next time…Bye!
