  • 1.  Using Yoga blocks (EVA foam) as supports in gallery

    Posted 11-25-2024 10:50
    Hi everyone, 

    While we currently use ethafoam planks under framed works while installing exhibitions, it has been suggested that we switch to using black yoga blocks made from EVA foam (for example - https://www.amazon.com/gp/aw/d/B0C3HP7YKC/ref=ox_sc_act_image_1?smid=A2FTPISBB57QJL&psc=1). I can't seem to find any information on whether this type of foam is safe to use around collections. Could anyone advise? I'm concerned both about the type of foam and any possible issues with the black colorant. 

    Also, if they are wrapped in tyvek, does that help prevent issues by creating a barrier and does this make them more acceptable to be used?

    Many thanks,
    Robin

    Hello,
    While we always want to use appropriate materials, since the contact with whatever material is used is short-term there can be a bit more leeway. Wrapping them in Tyvek or other barrier materials would add some peace of mind if there are concerns. My questions would be:

    • are the frames themselves considered part of the works or are they utilitarian? If the frames are not considered collection items then there is less of a concern with what they are coming into direct contact with.
    • are the blocks too hard/soft/providing proper support for the works being placed on them? Will they slide on floors with enough pressure or will they 'grip' the floors? I don't think I've ever handled yoga blocks and don't know if there are different types. You may need different consistencies for the different frames being placed on them.
    • even if a product says it is 'x', what are the other ingredients/materials used in it? Can you obtain a full list? If you are able to source them through a reputable conservation/preservation supplier who confirms they are suitable for use this is less of a concern. Also, since the contact with collections is short-term there may be a bit more leeway as noted above as long as the blocks aren't deteriorating or concerning in some way.
    • if it is a random supplier online, there may be some concern with what they are sending you is the same material as what they are advertising.

    One last thing that popped into my head, possibly you could visit a established yoga studio or reach out to a yoga group/community to see if they have any suggestions on high quality yoga blocks. CCI also has a resource that you might find helpful: Products Used in Preventive Conservation – Technical Bulletin 32
