A note to our customers. This year has been very challenging. Thank you for your patience and commitment to the products and services we provide you. During the Covid-19 pandemic we have been hit with a number of set backs that have slowed the processing of most orders. This includes a reduction in staff, following the recommended CDC guidelines, and manufacturing and shipping delays for all ceramic materials and equipment from our vendors. Despite these circumstances we are working hard to come up with creative ideas to quicken our response and get your orders to you as soon as we can.

Laguna Dry Glaze Mixing Instructions

Read carefully before mixing, write out your stepwise instructions before starting, formulate and mix per your glaze choice and specific application as indicated below. Wear appropriate gloves and mask while mixing your glaze. Approximately 8 to 11 ounces of water per pound of dry glaze will be needed, but the amount needed varies per glaze. Add additional water if glaze is too thick immediately after mixing. Some glazes gel when left undisturbed, mix aggressively before adding water during subsequent uses.

Low tech instructions (mixing with a dowel or narrow board)
  1. Measure 2/3rds of water into a clean plastic bucket.
    Reserve the other 1/3 of the water in a container which will allow you to pour it easily.
  2. Screen or sieve the dry glaze slowly into 2/3rds of the water in the bucket while continuously mixing. Scrape the sides and bottom of the bucket often and mix thoroughly.
  3. Check viscosity by dipping your gloved fingers and assess for appropriate thicknesses as described below.
    • clear dipping glazes   (half and half consistency)
    • color dipping glazes   (whole milk)
    • spraying   (heavy cream consistency)
    • brushing   (yogurt consistency) mix brushing medium with dry glaze prior to water or replace a portion of the water with gum solution

    Add the remainder of the water in portions. Stir and assess the thickness between each addition and do not add any more water after the desired thickness is obtained.

  4. Screen through the appropriate mesh after blending with water to achieve the desired results. (Typically, 80-100 mesh sieve) Disregard if specific glaze instructions state not to sieve.
  5. For best results allow to sit for a period of 24 hours before being remixed and then applied.

 

Power mixer instructions (mixing with a variable speed drill and a mixing attachment)
  1. Measure 2/3rds of water into a clean plastic bucket.
    Reserve the other 1/3 of the water in a container which will allow you to pour it easily.
  2. Screen or sieve the dry glaze slowly into 2/3rds of the water in the bucket while continuously mixing. Scrape the sides and bottom of the bucket often and mix thoroughly. Add the remainder of the water in portions. Stir, shut off the drill and assess the thickness between each addition by dipping your gloved fingers and assess for appropriate thicknesses as described below.
    • color dipping glazes   (whole milk)
    • clear dipping glazes   (half and half consistency)
    • spraying and 60-65 for brushing   (heavy cream consistency)
  3. When you see the approximate desired thickness, check viscosity with a hydrometer. The hydrometer reading should be approximately
    • 55 for color dipping glazes
    • 46-47 for clear dipping glazes
    • 60 for spraying
    • 65 for brushing.

    (Measuring a very thick material with a hydrometer can lead to a misleading result.)

  4. Screen through the appropriate mesh after blending with water to achieve the desired results. (Typically, 80-100 mesh sieve) Disregard if specific glaze instructions state not to sieve.
  5. For best results allow the mixed glaze to rest for a period of 24 hours before being remixed and then applying.

Batch Measurement Guidelines
Mix a small batch to determine your optimum water content.
