Starting a New Mosaic

I’ve been pretty busy making beads (petmemorybeads.com) the past couple of weeks, but today I took some time to start another mosaic. I started with a huge sheet of Spectrum light blue iridized glass that I have been holding onto for a long time. I cut a good sized chunk of it off so it would fit on my work space and started to make pieces for the mosaic.

What was left after I cut some off for the mosaic.

Next I cut the smaller piece of glass into strips, and then into squares, and again into triangles and started arranging them on the window where I drew a mermaid’s tail a week or two ago.

First I laid out the outline of her tail, then started filling in the gaps.

Laying out the edges first

I haven’t glued anything down yet, just getting a feel for how it looks. I need to eyeball it for awhile to make sure I like where it is going before I commit with glue. I plan on filling in some more and then decorating with some glass embellishments after I pour the resin. I also need to decide how I want to decorate the background areas – will there be shells and seaweed? Maybe some swirls and bubbles? Still need to figure that out.

Most of the basic shape complete

Varying the “waters”

I signed up for a space at a local farmer’s market for the months of September and October, so I have been trying to build up an inventory of small things (smaller glass pieces and coasters) to sell in addition to my stained glass in recycled windows. I also bought some various blue glass materials to use for the water in the beach coasters. I decided to try three different types of glass for this round of coasters. I really love the look of the “Blue Shells” glass, so I used that for some. Additionally, I used some fairy garden glass chips and another shade of larger (but still tiny) fairy glass globs.

Below is how the fairy glass globs looked when set in the resin.

I poured all of these coasters in two layers, one day apart. Since I learned that the type of resin I’m using is meant for thin applications, I went back to my old layering method of pouring. The demolding revealed another anomaly in the resin, however. The coasters with the fairy glass chips warped when they cured, so the tops of all four of them were uneven.

Poured coasters, 2nd layer

All the other coasters turned out to be fine, only the ones using that particular glass warped. They will obviously not be particularly useful as coasters with the tops so warped. After further inspection, I realized that one of the new molds I just purchased for coasters is defective, causing the warping. Unfortunately I wasted a lot of materials before I realized why the warping was occurring.

Another lesson learned. Luckily my new resins arrived today, so I can start using the proper resin for thicker molds going forward. The type I normally use is good for thin coatings only. I must just be fortunate that my previous coaster creations turned out fine using it!

Latest coasters – reveal

Here is how the latest batch of coasters came out. I was trying different colored pigments and also some new glass called “Blue Shells”. I *really* love this new glass. I bought it from Meyer Imports. By the way, I get no payment or promotion of any kind from any of the vendors whose products I use. I just share the info in case it helps someone.

I probably should have used more of the gold pigment in these, but I didn’t mix up enough. I can try this one again.

Trying new pigments

Since my coaster molds are a bit out of shape, I thought I would experiment with a couple of new colors of pigment I haven’t tried before while I wait for the new molds. I also wanted to make some other accent beads, so I thought this would be a good chance to try the colors in those molds as well.

Mixing Pigments

I used the purple pigment last week, and I wanted to make some additional beads using it. However, I hadn’t tried the Bronze or Gold pigments yet. The gold pigment is extremely light and flew all over the place when I was trying to mix it with the resin. I piped the colored resin into the bead molds right away. I wanted to do this quickly, since it is difficult to get the resin into them when it starts to thicken. I made several with the gold and purple and one with the bronze pigment.

Beads of each color

After pouring a thin layer of Envirotex Lite resin into eight of the coaster molds and removing bubbles with a heat gun, I added the pigmented resin on top. I then swirled them around a bit with my craft sticks. I also waited about 20 minutes before adding shells to two of the molds.

Adding decorative elements.
Glass called “Blue Shells”

I also have some new material to try using as the water element in the beachy coasters. It was very expensive, so I will likely limit using it to particularly special projects after today.

I waited until the resin was starting to thicken before adding the shells, and waited even longer (maybe 20 minutes) before adding the sand and the glass chips to the resin in the mold.

I decided there wasn’t enough of the gold pigment in the gold coaster molds, so I mixed up another medicine cup full using some that was left over from the initial batch of resin and added it to the molds. If all goes well overnight, I will add another clear layer of resin to the coasters tomorrow and demold the beads to see how they turned out. I am a bit leery of pouring another layer of resin today after the experience the other day with the resin turning yellow during curing. The manufacturer got back to me and recommended I use a different product, EasyCast, for molds / thicker applications. I can continue to use this type in 1/8″ layers, though. I can’t wait to see how they turn out!

Covered for curing overnight.

A few things completed

Here is some of the fruit of the labor of prior days. The sun mosaic is complete, and I have 8 coasters and some beads ready, as well.

Here comes the sun!

I had a new request for some memory beads, but I’m not yet sure what type she will want. Since I had some resin handy, I just made a selection of beads. They turned out pretty well!

Rondelle (6 mm hole), rondelle (5 mm hole), ball beads.

The coasters I made with the quick layering technique turned out OK. I think next time I will swirl the water pigmented layers a bit. I was hesitant to do that because the layer underneath wasn’t cured, but I think the pigments need to be moved around a bit more. I also think the look of the bubbles at the edge of the water are improved with this technique.

Quick layered coasters.

Multitasking

Today was a very busy, but productive, day. I finished the sun panel by pouring the resin over it, set a few memory beads in their molds, and made 8 coasters using the layer method where you don’t cure the resin overnight between layers. At times I felt like the proverbial one-armed paper hanger! It was a challenge doing all this in one day, but hopefully it was a success. I will find out tomorrow when I can take the beads and coasters out of their molds. Here is the basic rundown of the methodology and things to note.

Pouring the resin.

Pouring the resin on the sun mosaic was pretty straightforward, since everything was pretty much secured in place one way or another. I mixed up 16 ounces of resin and used almost all of it to cover the glass. After pouring, I immediately used my heat gun to help distribute the resin evenly across the window as well as to remove bubbles that form as the resin settles under the individual pieces of glass.

Pouring the resin.

I thought about adding some glass chips to the resin, like I had planned to do, but I just wasn’t sure how that would look in the end, so I decided to save that to try on a smaller project that won’t be such a big deal if I don’t like the way it ends up looking. I normally use the glass chips in a clear background, but this whole window has glass in it, so I chickened out.

Using the heat gun.

The difficult part comes after the resin is poured and bubbles start to emerge. For the next 45 minutes to an hour, I had to repeatedly use the heat gun to remove bubbles as they emerged in the resin.

Bubbles forming in the resin.

While I monitored the bubbles on the sun mosaic, I used a bit of the resin to make a few memory beads. The beads take very little resin, and I had enough left to make about four of them.

Using extra resin for some beads.

Since the bubbles in the mosaic weren’t slowing down, I decided to make another batch of resin and try to do the coasters in layers without curing in between. I read that this results in a stronger end product, though I haven’t had any “strength” issues with my previous creations.

First layer poured and decorated.

I poured about an ounce of resin in each mold, waited about half an hour, then started placing the shells, shark teeth, etc in the resin. I then waited about 2 hours before the next step.

Added the sand for the beach and the white bubbles.

First I added the sand for the beach, which I made smaller than usual in this batch. I mixed up just about 3 CCs of resin and added the white pigment, then drizzled it in a line along the edge of the “beach” using a small craft stick. I went back and added a bit more after it dissipated a little. I also had enough white resin left over to make a couple of experimental beads. The white resin still spread out a bit more than I anticipated. I just drizzled a thin line and by the time I took photos, it had spread into the sand.

Bubbles added.

I wanted to let this layer cure enough that it would be more gel-like than liquid, as I believe that causes the white pigment to spread out more than I want it to (I really want it to be a thin layer at the edge of the sand and water to look like bubbles when the waves are crashing at the beach). Since it was just a small amount of resin, that didn’t take very long, and I started mixing up the various colors of pigment for the water.

80 ccs of resin for pigment.

I mixed up 80 ccs of resin using a small silicone measuring cup, then split it evenly between the four medicine cups. I then scooped a bit of pigment powder into each cup and mixed it together. After all the colors were ready, I drizzled some of the Caribbean Blue (far right in the above photo) in a few lines into the mold. It will be interesting to see if making lines with the pigmented resin results in a different look for the water in the coasters.

Adding the first color for the water.

After that, I repeated the steps for each of the other three colors. I tried to fill in empty areas with each color. I didn’t add any of the water-pigmented resin to the sand, but I knew it would drift over it a bit after the last step.

Two colors added.
Adding colors.

I used up every last usable drop of the pigmented resin I mixed for the water. I really wanted to fill in all the gaps.

All four colors added.

The final step was to add the last layer of clear resin, so I mixed up my last batch of the day, 14 ounces of resin. The reason I go back and forth between ccs and ounces is because my measuring cups have different measurements which I use for different purposes, just for convenience and ease of reading. For some reason, these really had a lot of late-emerging bubbles – much more persistent than I usually see with coasters. That could be a side effect of not letting the layers cure fully between pours. Having to use the heat gun so much moved the pigment / water around quite a bit (at least on the bottom of the coasters). I might need to get a blow torch, as I think they might be more precise in removing bubbles without moving the resin around so much. I’m a bit impatient to see how these turn out, but I have no other choice but to wait until they fully cure to find out how they look. Unlike the sun mosaic, which I can look at while it cures. The only problem with that is keeping curious fingers out of the resin while it is still soft (yes, my children have been known to poke at things during this stage). Hopefully tomorrow I can bring it upstairs to photograph.

Resin curing.

Just a side note – I’m normally a day behind posting these, but I try to write the post the same day as I do the project so all the details are fresh in my memory. That means when I reference “today”, it’s not usually the same day as the post went live. I’ll actually be pulling these out of their molds on the 30th, but I will also schedule this to post on the 30th at a somewhat random time.

Pigment bubbles try #2

Today I was able to see how my second attempt at pigmented coasters with bubbles turned out. Overall, they are OK, but not quite to where I want them to be. I also put the last coat of paint on the window frame I’m going to use for my next mosaic project, which I’m thinking about using for a sun theme, or perhaps an aquarium.

Bubbles with sand dollars

The white pigment spread out more than I wanted, so they aren’t defining the edge of the waves as much as I had hoped. I think if I let the resin gel a bit more before I put the bubbles layer in place, then let the bubbles gel before pouring the blue pigmented resin for the water, that will give me more control. I will try that next.

A closer look.

Sand first coasters reveal

It’s time for the reveal of the coasters I made this week with the sand layer before the water. Spoiler alert, I like the water layer first final product a lot better.

All nine coasters

Here are my reasons. First, the water layer doesn’t distribute as well this way. I think pouring the pigmented resin on top of wet clear resin really makes it move more and look more like water. Even though I used a craft stick to make swirls in the water, they don’t look that different from the control coaster at the top left of the first photo, which I just poured and didn’t stir. (Does it sound like I’m talking about Martinis now?) Second, the sand comes up around the shells and other decorative items on the beach and makes it look like they are all suffocating.

No white pigment between the sand and water in this one.
White pigment “bubble” between the water and sand.

They’re still OK overall, but I think I will go back to my usual layering order. I do like the white pigment at the edge of the water / sand, but it will take some time for me to perfect my technique for placing it. However, I did an informal FB Friends poll and folks are really pretty much evenly split on whether they prefer bubbles or no bubbles. I guess I will have to keep making some of each!

Third layer of the sea

Today I added the third and final layer on my most recent batch of coasters – the water layer. Usually I do the water layer second, but I wanted to see how it would look if I applied it last. Hopefully we will see good results (in the next day or two, after it cures). For now, these are the basic steps I took in pigmenting the water and layering it in the coasters.

Mixing the “Natural Blue” pigment into the resin.

I mixed up about 8 ounces of resin, then poured about 2-3 tsp in three cups for the three different colors of resin. This turned out not to be anywhere near enough resin and I ended up mixing another batch of 200 ml later.

Three shades of blue. The third one is “Majestic Blue”. Sometimes I use a green, as well, but not today. The bold resulting colors using these pigments amazes me!
I poured the three colors into the mold over the first two resin layers that have already cured.
Close up view. It should be fine that the water/blue layer is over some of the sand since the sand is opaque. I will mix the colors in a later step and make sure any empty / clear spaces are filled.
Pouring more clear resin over the water / blue layer. Once the clear resin is on top, I can mix and move the colors around a bit to make it look more like water.

After pouring the clear layer, I gently blow the resin with a heat gun in order to remove any air bubbles that form. A few are OK, but I think too many bubbles detract from the final look of the piece.

I use a small craft stick to mix the blue colors in a circular motion.
Continue to mix the colors in a swirling motion.

Ready to cure.
Covered for the next 24 hours or so to keep dust out while they cure.

I need to stay close to the coasters I poured for the first hour or so after I pour them in case some bubbles emerge that need to be removed. For this, I use a heat gun, though many people prefer a craft blow torch. Hopefully everything will cure / harden nicely overnight and we can see how they turned out tomorrow evening.
