This workshop includes lectures and hands-on activities that will empower participants to incorporate new knowledge about gels and poultices into their conservation practice.


Stain reduction and removal remains a topic of special interest for textile conservators. In the past decade, significant research on the variations and effects of using gels, poultices, chelators, and other cleaning solutions has been shared, offering better understanding and control over this type of conservation treatment. In this in-person workshop, participants will gain further insight to make informed decisions regarding localized cleaning treatments on heritage textiles. Lectures will cover topics such as decision-making for cleaning, modifying aqueous solutions, and selecting delivery methods to achieve desired outcomes. During the course of two days, participants will make a variety of gels and test them on stained textile samples.


Laura Mina (she/her) is Conservator of Costumes & Textiles at the Smithsonian National Museum of African American History and Culture (NMAAHC). She has published, researched, and worked with different cleaning solutions and delivery methods for stain reduction on textiles for over a decade. From 2017-2021 she led textile conservation training in the Winterthur/University of Delaware Program in Art Conservation. She created and taught similar versions of this workshop in Taiwan (2019, three day in-person workshop), for CNCT (2021, five day virtual workshop: Chile and Argentina) and for the 50th AIC Annual Meeting (2022, two day in-person workshop).

Laura Garcia Vedrenne (she/her) is Assistant Textiles Conservator at the Fine Arts Museums of San Francisco (FAMSF). She has coordinated and organized two stain reduction workshops in collaboration with Laura Mina. She also translated the CNCT workshop content to Spanish. She created and taught a Preventative Conservation Workshop for Textile Objects in Mexico (2019, five day in-person workshop). She holds special interest in the workshop's topic, as shown on her master's dissertation which explored the low wash-fastness of indigo carmine dyes during wet cleaning.
