What is it about?

It's easy to eye-ball the plaster/water ratio using the island method when making an uncritical plaster piece, such as for the bottom of a wetbox. However, when making multi-part molds or a series of identical molds, the ratio is more critical to ensure consistency in the resulting ceramic piece.

App Store Description

It's easy to eye-ball the plaster/water ratio using the island method when making an uncritical plaster piece, such as for the bottom of a wetbox. However, when making multi-part molds or a series of identical molds, the ratio is more critical to ensure consistency in the resulting ceramic piece.

Plaster Calculator can help you determine the amount of plaster and water for your mix, ensuring consistent results based on the most common and recommended plaster for ceramics - #1 Pottery Plaster.

Key Features:
Calculate the volume of your plaster need based on the dimensions of the most common forms in centimeters, inches, or feet. Forms include square/rectangle (cuboid), cylinder, sphere/half-sphere, pyramid (3 and 4 sided), and cone, as-well-as allowing you to enter an already known volume amount.
Additionally, can calculate the volume of a void space in the plaster mold, such as when making a mold from an existing object, the volume of which will be removed from the main volume.

Allows measurement of plaster and water in pounds/ounces and kilograms/grams, the default can be changed in the Settings.

Calculates a typical volume reduction of 20% (as recommended by some sources). This value can be changed between 0 (no adjustment) and 35%, the default value can be changed in the Settings.

Provides plaster weight variations -/+5 points from the standard consistency for the plaster. For example, the standard consistency of #1 Pottery Plaster is 70, variations are provided from 65 to 75 supplying the plaster amount needed for that consistency.

Save your mix calculation for later referral.

Choose between three different colorations for the application - Blue, Gray, and Purple. More possibly to come!
