Lace Threads Have Arrived!

The lace threads for the project have arrived! After testing several threads (noted in earlier blog entries), we chose a family of threads fabricated by Benton and Johnson (www.bentonandjohnson.com). The diameter of the thread was close to that found on lace samples from the first quarter of the 17th century viewed at the Boston Museum of Fine Arts and the Metropolitan Museum of Art, as well as other locations.
This family of threads is manufactured to limit the amount of overtwist imparted to the core thread when wrapping the metal foil around the core. The manufacturer calls the line “Tambour” as it is primarily used by those who practice tambour embroidery. The line comes in two weights, 9 drms (thick diameter) and Fine (small diameter). The 9 drm version is what we are using.
The line also comes in a choice of metallurgy. We have been receiving a lot of questions to the blog and in private about the metallurgy of the lace threads. Of course one of the first considerations was to match the threads of the 17th century. Currently I have not found conservation literature on the exact metallurgy of lace threads that have been studied, while there is a body of knowledge on embroidery threads of this time period. But consultations with conservators who have a great deal of expertise with metal threads (Dr. Marta Jaro at the Hungarian National Museum is one of the best known) match the references in period accounts and imply that the metallurgy would not have been different between the lace and embroidery threads. Each would have started with a silver rod with gold leaf wrapped around it. This would then be drawn into a thin wire that was then flattened and wrapped (really be spun) around a silk or linen core thread. During the 17th century, a less expensive version of these threads was made using a copper rod with application of silver or silver and gold leaf, called ‘false gilt’ or ‘false silver-gilt’.
- 2% gold (a much thicker layer of gold on the predominately copper core, again with a possible layer of silver between)
- gilt (electroplated gold with a predominately copper core and possibly a thin layer of silver between)
Currently available silver threads are:
- 90% silver alloy
- silver plated (electroplated silver on a predominately copper core)
When deciding which of each version to use, we knew we would already be closer to the ‘false gilt’ threads of the day and not the more expensive versions made in the 17th century. We did explore the possibility of making silver cored wire, but the expense of nobel metals today and the #lbs we would have to manufacture would have been more than the entire cost of this project, so we had to back off of that level of authenticity. For similar reasons, we had already made the decision to use gilt and not 2% gold for the embroidery thread, so gilt for the lace threads was an obvious choice. For the silver threads, conservation drove the decision to use the significantly more expensive 90% silver threads. 
Silver tarnishes with a blue-black hue when exposed to sulfur, which is prevalent in low doses in the atmosphere and much higher doses in human sweat and in paper manufacture. Electroplated silver thread tarnishes in a very short time frame (a few years depending on storage) whereas 90% silver thread can last at least a decade, again depending on storage conditions. We have been looking at the conservation literature and decided that since this object would automatically become a museum object, destined for study in several decades, we would use the highest quality silver thread we could get. The literature specifies easy tests that will be used to evaluate the materials that will be used for the display cases and storage to help get the longest lifetime for our lace.
The lace threads have been on order for over a month and they arrived this week! With people doing less and less handwork, much of the gold thread industry has to make to order to save on inventory costs. We are starting to put together the lace kits and expect to ship them starting January 1st.
The lace in the kits is not the Laton lace from the jacket. The kit lace is shown in the photos here. The kit lace is similar to the Laton lace, and uses many of the same techniques. Each kit will contain:
- 110 spangles
- 24 yards of 90% silver 9 grm tambour
- 12 yards of gilt 9 grm tambour
- needle to thread spangles
- complete instructions, color diagrams, and pricking for lace
- Photograph of finished lace
The materials included are enough to complete the sample (about 6 inches in length and 1-1/4" in width) and a second full sample for the lace maker to keep.
The cost of each kit is $40.00 plus $5 shipping, which includes a $20 tax-deductible donation, which will directly support the jacket project.
To order a kit, please call Kathy at 508-746-1622 X 8114 or email at kroncarati@plimoth.org
If you have already put your name on the list for a kit, yours will go out in the first shipment. Just please contact Kathy to arrange a payment method.
We can start scheduling lace makers, two at a time, for the January sessions. You can let me know by phone or email (508-746-1622 X 8119 or jhall@plimoth.org) what session you’d like to attend. We only have room for two lacers at each session, so you’ll want to let me know as soon as you decide.
The dates for the January sessions at which we can accept lacers are:
Sunday January 20 – Wednesday January 23
Wednesday January 23 – Saturday January 26
And in February:
Friday February 8 – Monday February 11
Monday February 11 – Thursday February 14





These are just the directions for the old embroidered coif kit, not the kit itself with the design-stamped cloth and floss. But many people have asked for the directions so we’ve made them available.
